You're listening to a podcast from Mooshu Nature
Documentaries. Today, we're setting our sights
on a truly iconic bird. When you've probably seen, I'm
talking about the great egret. Whether it's waiting gracefully
in a marsh somewhere, maybe herein southern Canada, or perched
up high on a tree, it's kind of a global symbol of natural
beauty. But while there's so much more
to this bird than just its looks, we're going on a journey
(00:24):
today to uncover what really makes the great egret and
ecological marvel. Yeah, it's definitely worth
unpacking because the great Egret Ardea Alba, it isn't just
beautiful, it's really a testament to nature's ingenuity.
What's fascinating here is how truly adaptable this species is.
I mean, it stands as one of the most widespread herons globally,
thriving across nearly every continent.
(00:45):
Yeah, that pristine all white plumage just grabs your
attention. But like so much in nature, it's
elegance isn't just for show, isit?
It's whole anatomy seems like a masterpiece of natural
engineering when you look at itsdesign.
Those incredibly long slender legs and toes, that really
unique shaped neck. What's the most surprising bit
of engineering there that helps it survive?
(01:05):
Well, the surprise, I think, often lies in just how
specialized each part is, but how broadly effective the whole
package remains. Take those super long legs and
those finely spread toes. They're just perfect for waiting
silently through shallow water. They let the egret move with
almost, well, imperceptible grace, so its prey often has no
idea it's even. There complete stealth mode.
(01:26):
Exactly. And that S shaped neck, it's not
just about looking graceful. It acts like a powerful coiled
spring. It allows for this astonishingly
rapid and precise strike. It can spear elusive prey like
fish or frogs with lightning speed.
Think about it. This seemingly slow, patient
bird can unleash a strike fasterthan, well, faster than we can
(01:46):
often even register. That combination, the stealth
and that explosive speed makes it an incredibly efficient
hunter. That blend of grace and lethal
precision really is something. OK, what about the iconic white
plumage and that impressive wingspan?
You said it can reach what, 1.3 to 1.7 meters?
Are these just aesthetics, or dothey have practical purposes we
might not immediately think of? Oh, definitely practical.
(02:07):
Neither is just for looks. The old white plumage may be
surprisingly serves as camouflage when you view it from
below. Like a fish wood, it blends into
the bright sky pretty effectively.
Makes the egret almost invisiblefrom underwater.
I wouldn't have thought of. That.
Yeah. And it also plays a role in
thermoregulation, especially in hotter places.
(02:28):
It reflects sunlight, helps birds stay cool.
As for that large wingspan, well, that's a marvel for energy
efficiency. It allows for incredibly
efficient flight, especially over long distances.
During migration, great egrets can soar and glide for ages with
minimal energy use. That's a huge advantage when
you're crossing vast distances. And we shouldn't forget their
(02:49):
vision. Super keen eyesight is
absolutely crucial for spotting prey underwater and judging
distances with remarkable accuracy before that lightning
strike. Happens so it's whole body is
this finely tuned instrument forsurvival.
But is it always the same instrument?
Does the egret change its appearance through the year or
maybe at different life stages? Oh, they definitely changed.
They aren't static at all. The great Egret undergoes some
(03:12):
really distinct seasonal and life age transformations,
especially around breeding time.That's when they developed those
exquisite ornamental plumes on their backs, the egrets.
Those are the very feathers thatalmost led to their extinction,
you know, back in the plume trade days.
The fashion craze that nearly wiped them.
Out exactly and at the same time, that patch of skin between
(03:34):
their eyes and Bill Flores, it turns this vivid, almost neon
green. It's all about attracting a
mate. The males especially use these
elaborate visual signals and displays to interest the
females. Those visual cues are vital for
courtship. What about the young ones, the
juveniles? Do they look the same or are
there differences? There are definitely
(03:54):
differences. Juvenile great egrets.
They don't have that striking pure white plumage yet.
It's usually a bit duller. Their bills are darker too,
often grayish or a dull yellow, not the bright yellow of a
mature adult. And their legs and feet are
lighter, maybe greyish. As they mature, the bill
brightens to that characteristicyellow and the legs and feet
darkened to black that signals they're fully ready to breed.
(04:17):
Interestingly, there's very little sexual dimorphism.
I mean males and females look very similar most of the year.
It's really only those subtle variations in the breeding
plumes and lores colour during that season.
That makes sense. Those subtle cues must be really
important when telling males andfemales apart is otherwise
tricky from afar. OK, given their huge range from
(04:38):
hot tropics to cooler temperate zones, even up here in southern
Canada where temperatures can swing wildly, how do they manage
these temperature extremes? Do they have some kind of built
in thermostat? They do, and it's this
remarkable mix of behavioral andphysiological tricks.
In hot weather, you might see them adjust their posture, maybe
stand with their wings slightly open, you know, to get some air
flow over their bodies and dissipate heat.
(05:00):
They'll also actively seek shadeduring the hottest parts of the
day. Physiologically, they can pant
quite rapidly. That helps with evaporative
cooling, much like a like a dog does, right?
And for the cold, which is really relevant in places like
southern Canada, even Quebec, they have this ingenious system
in their legs. It's called countercurrent heat
exchange. Basically it minimizes heat
(05:21):
loss. Warm arterial blood flowing down
warms up the cooler venous bloodreturning to the body.
It conserves crucial body heat very efficiently.
And of course, they're feathers provide fantastic insulation.
They trap air for warmth when it's cold, or they can fluff
them up a bit for cooling when it's warm.
This incredible adaptability is key to them thriving in such
(05:42):
varied climates, from the human Amazon right up to the sometimes
chilly wetlands here. Their widespread nature really
is striking, so we've covered their amazing lifts and how they
cope with different temperatures.
Let's talk about where these elegant birds actually hang out.
We know they're global, but whatspecific spots do they prefer
and how do they handle landscapes?
We've changed. Well, like we said, their
distribution is vast. They're truly cosmopolitan,
(06:04):
found across the Americas, Europe, Africa, Asia, Australia,
pretty much everywhere except Antarctica.
Here in North America, you'll find them from southern Canada,
especially in the wetlands of Quebec and Ontario during the
breeding season, all the way down through the US into Central
and South America. They are quintessential wetland
birds. Their habitat choice is really
driven by 1 main thing, shallow water.
(06:27):
So you'll find them at a huge diversity of wetland
environments, freshwater marshes, ponds, lakes, rivers,
but also brackish and saltwater marshes, estuaries, even
tropical mangrove forests. And what's really remarkable is
their adaptability to human modified places.
It's not unusual at all to see them foraging and flooded rice
fields or other agricultural lands to get flooded.
(06:48):
You might even see them in urbanparks or reservoirs, as long as
they're shallow water and something to eat.
This ability to use disturbed landscapes is a big part of
their success story. They aren't just wilderness
birds. OK, but do they stay put once
they find a good spot or are they travelers?
Are great egrets homebodies or nomads?
Many populations are definitely travelers.
They show pretty distinct seasonal movements, migration
(07:12):
patterns, though it varies a lotby region.
Take North America for instance.The populations that breed up
north, including southern Canadaand the northern US, they
undertake significant migrations.
When it gets cold, they head South to warmer wintering
grounds that could be the southern US, Central America,
the Caribbean, some even go as far as South America.
But then you contrast that with populations inconsistently warm
(07:34):
tropical areas like parts of Africa or Australia.
Those tend to be much more sedentary.
They might not move very far from their breeding grounds year
round. Interesting.
So it really depends on the local climate and food.
Exactly, it highlights how they optimize for resources.
And it's worth remembering theirhistory here too.
They face that massive decline late 19th early 20th century
(07:55):
because of the plume trade for hats.
They're recovery driven by earlyconservation like the Audubon
Society forming and the crucial Migratory Bird Treaty Act of
1918. It's honestly one of the most
inspiring conservation success stories out there.
It led to their amazing rebound and even range extension, like
pushing northward into Europe more recently.
That really is a powerful reminder of what can be achieved
(08:17):
when people decide to act. OK, let's switch to their diet.
What's on the menu for a great egret?
And how do they actually go about hunting using all those
specialized tools we talked about?
Right, so they're carnivores andthey have a wonderfully diverse
and opportunistic diet. The main thing they're staple is
fish, but they're definitely opportunistic.
They'll readily eat amphibians, frogs, toads, small reptiles
(08:38):
like snakes and lizards, or FairGame 2 + a wide range of
invertebrates, crayfish, shrimp,aquatic insects, and
occasionally, if the chance arises, they might even snatch a
small mammal or a bird. As for hunting techniques, they
are masters of patience. They often use that stand and
wait approach, just standing perfectly still, sometimes for
ages, until prey comes within striking range.
(09:01):
It's like watching a statue cometo life.
I've seen that they barely seem to move.
Exactly. You could almost walk right past
one and then suddenly Wham, thatincredibly fast strike.
That patience is something else.Alternatively, they might stalk
prey very slowly, taking these deliberate, measured steps the
water. Or sometimes they'll even stir
the water with their feet, trying to flesh out hidden
creatures and then quickly nab whatever emerges.
(09:24):
Amazing how they have these different strategies.
So beyond just feeding themselves, what ecological role
do they play? Do they help control other
populations, maybe even pests? Oh, absolutely.
They play a really significant role in population control,
which has broader benefits for the ecosystem.
In aquatic systems, By eating fish and amphibians, they help
(09:44):
keep those populations in balance.
They prevent any one species from becoming too dominant.
That contributes to the overall health and biodiversity of the
wetland. That keeps things in check.
On the terrestrial side or in agricultural areas, they're
actually valuable natural pest controllers.
They eat insects like grasshoppers and beetles, and
also small rodents like mice andvoles, which can cause a lot of
(10:04):
crop damage. Think about the Florida
Everglades. They're crucial for balancing
fish and amphibian numbers there.
Or an Asian rice paddies. They help control insects,
sometimes reducing the need for pesticides.
That's a tangible benefit. So they're not just beautiful,
they're working parts of the ecosystem providing services.
But what about the other side ofthe coin?
What praise on the great Egret? Despite their size and skills,
(10:26):
what makes them vulnerable? Right, even though adult grade
egrets are large, have that sharp bill, and are pretty
vigilant, they aren't completelyimmune.
Raptors, Hawks, eagles, owls could be a threat, especially to
younger birds, but sometimes adults too.
Attacking from above mammals like raccoons, foxes, Bobcats.
They mostly go after eggs and chicks in the nests,
(10:48):
particularly if the nests aren'tcompletely surrounded by water
and are easier to reach and in places where they coexist.
Large reptiles like certain snakes or alligators can
definitely prey on young egrets that are near the water, but
they have defences. Colonial nesting is a huge one.
Safety in numbers. They often nest in these big
colonies, rookeries, usually in trees or shrubs over water.
(11:10):
That makes it really hard for ground predators to get to.
A smart strategy. And their vigilance is key.
If one egret spots danger, it'lloften give an alarm call warning
the whole colony. If a predator gets too close.
There are strong flight allows for a quick escape and they can
also put on aggressive displays,spread their wings, lunge
forward to try and look bigger and more intimidating.
(11:30):
It sounds like survival is really tied to finding that
sweet spot. Good food nearby but also safe
nesting. How directly does food
availability influence where they decide to live or what they
do during the year? Oh, food availability is
absolutely critical. It drives so much of their
behavior and their distribution.It directly influences how they
forage. If food is abundant, they might
(11:51):
spend less time actively hunting, maybe be less
territorial about a feeding spot.
But if resources are scarce, they could become quite fiercely
territorial over a good area. And in terms of their bigger
movements, food availability is the main driver behind those
migration patterns we discussed.Populations in colder places
like southern Canada have to migrate to find areas where the
(12:11):
water stays open and food is accessible all winter.
It also heavily influences theirhabitat selection.
Day-to-day or season to season, they'll move to areas with
reliable water and food. You see, that's when floods
happen. In places like Australia, egrets
might move inland temporarily toexploit newly flooded areas.
And crucially, breeding sites are almost always chosen because
they're near abundant food sources.
(12:33):
Parents need easy access to enough food to feed those
demanding chicks. Fascinating how it all connects.
OK, let's dive into their familylife.
We know about the fancy breedingplumage, but what about the
timing? Does the breeding season vary
much say between here and somewhere tropical?
Yes, absolutely. The breeding season for the
(12:54):
Great Egrid definitely varies depending on where.
They are mostly driven by the local climate and when food is
most abundant. In temperate regions like here
in North America, including southern Canada and the US,
breeding typically gets going inlate spring and runs into early
summer. You might see them starting
nests as early as March or April, but the peak activity is
(13:14):
usually May in June. This timing lines up perfectly
with warmer weather and, critically, the peak
availability of fish and amphibians needed to feed the
checks. Right, gotta time it for the
buffet. Exactly.
But then you go to more tropicalregions like, say, the pants and
all in Brazil. There the breeding season is
more variable. That often lines up with the wet
season, maybe November to March.That's again when seasonal rains
(13:36):
boost food resources. Makes perfect sense.
Timing is crucial when you're raising young, especially with
the fluctuating food supply. OK, walk us through the main
stages of their life cycle, fromthe egg right up to a fully
independent adult. Sure, it's quite a journey.
It starts, of course, with the egg stage.
The female usually lays one to six pale blue-green eggs. 3 or 4
(13:59):
is pretty common, and both parents share incubation duties.
That takes about 23 to 26 days. Then comes the hatchling stage.
When the chicks hatch their altricial.
Basically helpless, blind, can'tregulate their temperature,
totally dependent. Both parents were constantly
feeding them regurgitated food. It's messy, but essential.
(14:19):
This stage can be pretty intense.
There's often strong sibling rivalry.
Stronger chicks might outcompeteweaker ones for food, which can
sadly lead to siblicide mabinty.The stronger ones might push the
weaker ones out, or they just starve.
It's a tough reality, driven by how much food the parents could.
Bring Wow, that's a stark reminder of just how tough
survival is right from the start.
So after that intense beginning,what's next?
(14:40):
Well, after the hatchling stage,they move into the fledgling
stage. This happens around six to seven
weeks after hatching. The young egrets start
developing their flight feathers, get bigger, and begin
venturing out of the nest, practicing flying.
They're pretty clumsy at first. I bet learning to fly those big
wings. Exactly.
Lots of awkward flapping and landings initially, but they
(15:01):
keep at it. They're still dependent on their
parents for food and protection for several more weeks, though,
because they aren't skilled hunters yet.
After that comes the juvenile stage.
Now they're fledged, flying, butstill growing and really honing
those hunting skills. You can tell them apart.
Their language is a bit duller white than the adults.
Their bills are often a dull yellow or grayish, not that
(15:22):
bright yellow, and their legs are usually lighter grayish, not
black. Behaviorally, they're obviously
less experienced hunters. They spend a lot of time
learning, watching adults, practicing.
They're also more social, often hanging out in flocks with other
young egrets. That offers safety and probably
helps them learn from each othertoo.
And then finally, they reached the iconic adult form.
(15:45):
What does the adult stage look like behaviorally, and how do
they actually go about attracting and choosing a mate?
Is it some big elaborate dance? They typically reach the adult
stage at around 2:00 to three years old.
That's when they become sexuallymature.
They get that stunning pure white plumage, the black legs,
the bright yellow bill. And they returned to those
colonial nesting sites, the rookeries, year after year to
(16:07):
breed. And yes, attracting a mate is
quite an elaborate affair, especially during breeding
season. The males really put on a show.
They display those magnificent breeding plumes, the egrets,
very prominently. They perform specific courtship
displays. 1 famous one is the stretch display.
The male stretches his neck way U points his bill to the sky,
fans out his plumes, might spread his wings a bit.
(16:29):
They also do wing flapping, mutual preening and something
called bill clapping. Rapidly opening and closing the
bills make a clicking sound. Sounds noisy.
It can be. Often the male starts building a
basic nest platform, kind of like an invitation.
If a female likes what she sees,she'll join him to finish the
nest. That act of building together
really solidifies their pair bond.
(16:49):
All these mutual behaviors and calls ensure they cooperate well
during nesting and chick rearing, which is obviously very
demanding. That's a lot of effort.
OK, so once that pair bond is solid and the eggs are laid,
what's the parenting like? Are they sharing the load
equally or does one parent do more?
There are definitely proponents of cooperative parenting.
(17:11):
Both the male and female are heavily involved right through
the whole process for nest building.
Often the male gathers most of the sticks and twigs, but the
female usually does the detailedarranging, making it sturdy.
Then they both take turns incubating the eggs, ensuring
they're always warm and protected.
Once the chicks hatch, both parents are busy feeding them
that regurgitated food, and they're both vigilant
(17:34):
protectors, guarding the nest and young against predators like
raccoons or maybe aerial threatslike Hawks.
This shared responsibility is absolutely crucial, especially
thinking back to that brood reduction idea.
If food is scarce, having two parents working might just
ensure at least one chick makes it.
Fledging is gradual. Young start leaving the nests
around six or seven weeks, but they still rely on parents for
(17:56):
food and protection for several more weeks while they learn the
ropes of hunting and independence.
And as they make that slow transition to being on their
own, how do the juveniles reallydiffer from adults beyond just
the colour of their bills and legs?
What are the key behavioral things we might notice if we're
watching them? Yeah, beyond those physical
markers, the duller white dollarbill, lighter legs compared to
(18:16):
the adults, crisp looks, the behavioral differences are quite
striking. Juveniles are just much less
experienced hunters. You'll see them spend a lot more
time learning, practicing, maybemaking clumsy attempts or just
observing adults intently. They're also noticeably more
social. You often find them in flocks
with other youngsters. There's safety in numbers, plus
(18:37):
it's likely a key way they learnby watching their peers.
Their calls are different too. Less varied, maybe softer, often
more focused on those demanding begging calls when they're still
relying on parents. And they're slight, while
capable, is often less graceful than in adults.
They're still mastering those big wings and navigating tricky
landings. It really looks like a learning
phase. It's amazing to think about that
(18:58):
whole journey from helpless hatchling to that graceful,
efficient hunter we see. OK, let's bring this towards the
present and future. What does all this mean for the
Great Egrets? Continued success?
What challenges are they facing right now?
I know that IUCN lists them as Least Concern, but I guess that
doesn't mean everything's perfect.
You're absolutely right, Least Concern is good news reflecting
(19:21):
their large population and wide range, but it definitely doesn't
mean no concern or no threats. While there.
Recovery from the plume trade isa huge conservation win.
Great egrets face several reallysignificant ongoing threats
today that need constant attention.
Probably the biggest one globally is habitat loss and
degradation. Wetlands are still being drained
(19:42):
for agriculture. Urban sprawl, infrastructure
projects and deforestation can also impact them as they need
those trees near water for nesting safely.
So human expansion continues to put pressure on their homes.
What about pollution? They rely so much on water.
Pollution is a major pervasive issue.
Chemical contaminants like pesticides running off farm
fields, or heavy metals like mercury and lead from industrial
(20:05):
sources. These can build up in the food
chain and end up in the E grips that can impact their health,
their reproductive success. Egg shell thinning.
All sorts of problems. Oil spills are devastating too,
obviously coating their feathers, but also through
ingestion when they try to preen.
And we're increasingly worried about plastic pollution.
They can ingest larger pieces, get entangled, or potentially
(20:27):
suffer effects from microplastics accumulating in
their systems. Then there's climate change.
This is a big systemic threat that makes many other problems
worse. Sea level rise can wipe out
coastal wetlands or change the salinity, making them
unsuitable. More frequent and intense storms
can destroy entire nesting colonies.
Changing temperatures affect prey availability, and we're
(20:47):
seeing phenological shifts wherethe timing of breeding or
migration gets out of sync with when their food is available.
That mismatch can be really damaging.
That paints a pretty challengingpicture.
Are there other human factors causing problems?
Yes, direct human disturbance isstill an issue.
Recreational activities like boating, fishing, even just
people getting too close to nesting colonies can cause
(21:09):
stress and lead birds to abandoned nests.
While the large scale plume hunting is gone, illegal
poaching can still happen in some parts of their range.
And invasive species, both plants and animals, can disrupt
things too. Invasive plants might choke out
native vegetation they rely on, while invasive animals might
compete for food or even prey oneggs or chicks.
So yeah, well, at Least Concern is the current status.
(21:31):
It's something that requires ongoing vigilance and action to
maintain. It's a sobering list, but as you
said, their comeback story is a huge +1 of the main conservation
efforts happening now. How do they build on those early
successes? Thankfully, yes, there are
strong ongoing conservation efforts really building on that
historical foundation. Historically, that Migratory
(21:52):
Bird 3D Act of 1918 was pivotal,making plume hunting illegal,
and organizations like the Audubon Societies were crucial
in raising awareness and pushingfor change.
Today, a huge focus is still on habitat protection and
management. That means establishing and
carefully managing wildlife refuges and other protective
areas. Think of places like the
Everglades National Park in Florida, or major wetlands like
(22:14):
Horicon Marsh and Wisconsin, or numerous provincial parks and
conservation areas across southern Canada, including
Quebec, that provide vital breeding and foraging grounds.
And given their global range, are there international efforts
too? Absolutely.
Since many populations migrate across borders, international
cooperation is essential. They benefit from agreements
like the Ramsar Convention, which focuses on conserving
(22:36):
important wetlands globally, andthe Bond Convention, aimed at
protecting migratory species. Beyond formal protection,
continuous monitoring and research are vital.
Scientists track populations, study their ecology, figure out
what works best for conservation.
And public education remains really important, making people
aware of how valuable wetlands are and fostering sense of
(22:57):
stewardship for the egrets and other wildlife that depend on.
So, looking beyond their own survival and conservation,
what's the bigger ecological picture?
What role does the Great Egret play?
What does its presence tell us? Their role is much bigger than
just themselves. It's really foundational for
healthy ecosystems. As we mentioned, they're
considered a key indicator species for wetland health.
(23:18):
Their numbers and breeding success act like a vital sign
for the whole system. If egret populations are
struggling, it often signals wider problems like pollution or
habitat degradation, sometimes before we notice impacts on
other species. As top predators and many
aquatic food webs, they play critical role in regulating prey
populations, fish, amphibians, invertebrates.
(23:40):
By keeping those in check, they prevent anyone group from
becoming too dominant, which helps maintain balance and
benefits aquatic plants too. And historically they're brushed
with extinction due to the plume.
Trade was a catalyst. I fundamentally shifted how
people thought about conservation, highlighted the
need to protect entire ecosystems, not just single
species. It really sparked A broader
movement. Plus, as we touched on, in
(24:01):
agricultural areas, they providethat natural pest control
service, eating insects and rodents, which is a direct
benefit. It's amazing how their own
crisis helped launch the modern conservation movement.
So how do Great Egrets actually contribute to science itself?
Are they in a way helping us understand the natural world
beyond just being an indicator? They absolutely are.
In many ways, they're like natural collaborators for
(24:23):
scientists. Their role as an indicator makes
them invaluable for environmental monitoring,
studying their health, checking for contaminants and their
tissues, tracking their numbers.This helps us assess water
quality and pollutant impacts across large areas.
They contribute hugely to basic ecological studies too.
Watching them helps us understand wetland food webs,
(24:43):
foraging behavior, how differentspecies use habitats,
competition, all sorts of fundamental ecological
questions. And their recovery story is a
powerful case study in conservation biology itself.
It shows what works, protective laws, habitat restoration.
Plus they're very visible. Courtship displays and colonial
nesting make them great subjectsfor behavioral studies teaching
(25:05):
us about avian reproduction and pair bonding, social dynamics in
colonies and with climate change.
Tracking shifts in their migration timing, breeding
success or where they're found can give us crucial early
warnings about how ecosystems are responding to a warming
world. That's a lot of information they
provide just by living their lives.
But what are those lingering questions?
What are the biggest gaps we still need to fill?
(25:26):
Ohe despite everything we know, there are definitely still big
questions, which makes it exciting for future research.
We need more detail on migrationconnectivity.
Knowing precisely which breedingpopulations winter and which are
Pacific areas is vital for targeting conservation
effectively across their full annual cycle.
Getting a more comprehensive picture of climate change
impacts is crucial. How exactly will change in water
(25:49):
levels, temperatures, storm frequency affect their specific
food sources, nesting sites? Long term?
Understanding their genetic diversity across their vast
range is important for ensuring long term resilience.
Are some populations more isolated than others?
We could also use a deeper understanding of their complex
ecological interactions. How do they really fit into food
(26:09):
webs, especially as environmentschange?
What an incredible journey through the life of the great
egret, from their well, just their striking beauty and those
really sophisticated adaptationsfor hunting and surviving, to
their critical role as indicators of wetland health and
that inspiring comeback story. These birds really do embody
resilience and the deep interconnectedness of our
(26:30):
natural world. They remind us that conservation
isn't a one time fix, it's a continuous process and the
health of one species like the egret often truly reflects the
health of an entire ecosystem. Their story is such a powerful
testament to what collective action can achieve, but it's
also a constant call for vigilance.
Isn't. It indeed it is the Great Egrets
journey, you know, from being nearly wiped out to becoming
(26:52):
widespread again, it's a real beacon of hope.
You're listening to a podcast from Mooshu Nature
Documentaries. Today, we're setting our sights
on a truly iconic bird. When you've probably seen, I'm
talking about the great egret. Whether it's waiting gracefully
in a marsh somewhere, maybe herein southern Canada, or perched
up high on a tree, it's kind of a global symbol of natural
beauty. But while there's so much more
to this bird than just its looks, we're going on a journey
(00:24):
today to uncover what really makes the great egret and
ecological marvel. Yeah, it's definitely worth
unpacking because the great Egret Ardea Alba, it isn't just
beautiful, it's really a testament to nature's ingenuity.
What's fascinating here is how truly adaptable this species is.
I mean, it stands as one of the most widespread herons globally,
thriving across nearly every continent.
(00:45):
Yeah, that pristine all white plumage just grabs your
attention. But like so much in nature, it's
elegance isn't just for show, isit?
It's whole anatomy seems like a masterpiece of natural
engineering when you look at itsdesign.
Those incredibly long slender legs and toes, that really
unique shaped neck. What's the most surprising bit
of engineering there that helps it survive?
(01:05):
Well, the surprise, I think, often lies in just how
specialized each part is, but how broadly effective the whole
package remains. Take those super long legs and
those finely spread toes. They're just perfect for waiting
silently through shallow water. They let the egret move with
almost, well, imperceptible grace, so its prey often has no
idea it's even. There complete stealth mode.
(01:26):
Exactly. And that S shaped neck, it's not
just about looking graceful. It acts like a powerful coiled
spring. It allows for this astonishingly
rapid and precise strike. It can spear elusive prey like
fish or frogs with lightning speed.
Think about it. This seemingly slow, patient
bird can unleash a strike fasterthan, well, faster than we can
(01:46):
often even register. That combination, the stealth
and that explosive speed makes it an incredibly efficient
hunter. That blend of grace and lethal
precision really is something. OK, what about the iconic white
plumage and that impressive wingspan?
You said it can reach what, 1.3 to 1.7 meters?
Are these just aesthetics, or dothey have practical purposes we
might not immediately think of? Oh, definitely practical.
(02:07):
Neither is just for looks. The old white plumage may be
surprisingly serves as camouflage when you view it from
below. Like a fish wood, it blends into
the bright sky pretty effectively.
Makes the egret almost invisiblefrom underwater.
I wouldn't have thought of. That.
Yeah. And it also plays a role in
thermoregulation, especially in hotter places.
(02:28):
It reflects sunlight, helps birds stay cool.
As for that large wingspan, well, that's a marvel for energy
efficiency. It allows for incredibly
efficient flight, especially over long distances.
During migration, great egrets can soar and glide for ages with
minimal energy use. That's a huge advantage when
you're crossing vast distances. And we shouldn't forget their
(02:49):
vision. Super keen eyesight is
absolutely crucial for spotting prey underwater and judging
distances with remarkable accuracy before that lightning
strike. Happens so it's whole body is
this finely tuned instrument forsurvival.
But is it always the same instrument?
Does the egret change its appearance through the year or
maybe at different life stages? Oh, they definitely changed.
They aren't static at all. The great Egret undergoes some
(03:12):
really distinct seasonal and life age transformations,
especially around breeding time.That's when they developed those
exquisite ornamental plumes on their backs, the egrets.
Those are the very feathers thatalmost led to their extinction,
you know, back in the plume trade days.
The fashion craze that nearly wiped them.
Out exactly and at the same time, that patch of skin between
(03:34):
their eyes and Bill Flores, it turns this vivid, almost neon
green. It's all about attracting a
mate. The males especially use these
elaborate visual signals and displays to interest the
females. Those visual cues are vital for
courtship. What about the young ones, the
juveniles? Do they look the same or are
there differences? There are definitely
(03:54):
differences. Juvenile great egrets.
They don't have that striking pure white plumage yet.
It's usually a bit duller. Their bills are darker too,
often grayish or a dull yellow, not the bright yellow of a
mature adult. And their legs and feet are
lighter, maybe greyish. As they mature, the bill
brightens to that characteristicyellow and the legs and feet
darkened to black that signals they're fully ready to breed.
(04:17):
Interestingly, there's very little sexual dimorphism.
I mean males and females look very similar most of the year.
It's really only those subtle variations in the breeding
plumes and lores colour during that season.
That makes sense. Those subtle cues must be really
important when telling males andfemales apart is otherwise
tricky from afar. OK, given their huge range from
(04:38):
hot tropics to cooler temperate zones, even up here in southern
Canada where temperatures can swing wildly, how do they manage
these temperature extremes? Do they have some kind of built
in thermostat? They do, and it's this
remarkable mix of behavioral andphysiological tricks.
In hot weather, you might see them adjust their posture, maybe
stand with their wings slightly open, you know, to get some air
flow over their bodies and dissipate heat.
(05:00):
They'll also actively seek shadeduring the hottest parts of the
day. Physiologically, they can pant
quite rapidly. That helps with evaporative
cooling, much like a like a dog does, right?
And for the cold, which is really relevant in places like
southern Canada, even Quebec, they have this ingenious system
in their legs. It's called countercurrent heat
exchange. Basically it minimizes heat
(05:21):
loss. Warm arterial blood flowing down
warms up the cooler venous bloodreturning to the body.
It conserves crucial body heat very efficiently.
And of course, they're feathers provide fantastic insulation.
They trap air for warmth when it's cold, or they can fluff
them up a bit for cooling when it's warm.
This incredible adaptability is key to them thriving in such
(05:42):
varied climates, from the human Amazon right up to the sometimes
chilly wetlands here. Their widespread nature really
is striking, so we've covered their amazing lifts and how they
cope with different temperatures.
Let's talk about where these elegant birds actually hang out.
We know they're global, but whatspecific spots do they prefer
and how do they handle landscapes?
We've changed. Well, like we said, their
distribution is vast. They're truly cosmopolitan,
(06:04):
found across the Americas, Europe, Africa, Asia, Australia,
pretty much everywhere except Antarctica.
Here in North America, you'll find them from southern Canada,
especially in the wetlands of Quebec and Ontario during the
breeding season, all the way down through the US into Central
and South America. They are quintessential wetland
birds. Their habitat choice is really
driven by 1 main thing, shallow water.
(06:27):
So you'll find them at a huge diversity of wetland
environments, freshwater marshes, ponds, lakes, rivers,
but also brackish and saltwater marshes, estuaries, even
tropical mangrove forests. And what's really remarkable is
their adaptability to human modified places.
It's not unusual at all to see them foraging and flooded rice
fields or other agricultural lands to get flooded.
(06:48):
You might even see them in urbanparks or reservoirs, as long as
they're shallow water and something to eat.
This ability to use disturbed landscapes is a big part of
their success story. They aren't just wilderness
birds. OK, but do they stay put once
they find a good spot or are they travelers?
Are great egrets homebodies or nomads?
Many populations are definitely travelers.
They show pretty distinct seasonal movements, migration
(07:12):
patterns, though it varies a lotby region.
Take North America for instance.The populations that breed up
north, including southern Canadaand the northern US, they
undertake significant migrations.
When it gets cold, they head South to warmer wintering
grounds that could be the southern US, Central America,
the Caribbean, some even go as far as South America.
But then you contrast that with populations inconsistently warm
(07:34):
tropical areas like parts of Africa or Australia.
Those tend to be much more sedentary.
They might not move very far from their breeding grounds year
round. Interesting.
So it really depends on the local climate and food.
Exactly, it highlights how they optimize for resources.
And it's worth remembering theirhistory here too.
They face that massive decline late 19th early 20th century
(07:55):
because of the plume trade for hats.
They're recovery driven by earlyconservation like the Audubon
Society forming and the crucial Migratory Bird Treaty Act of
1918. It's honestly one of the most
inspiring conservation success stories out there.
It led to their amazing rebound and even range extension, like
pushing northward into Europe more recently.
That really is a powerful reminder of what can be achieved
(08:17):
when people decide to act. OK, let's switch to their diet.
What's on the menu for a great egret?
And how do they actually go about hunting using all those
specialized tools we talked about?
Right, so they're carnivores andthey have a wonderfully diverse
and opportunistic diet. The main thing they're staple is
fish, but they're definitely opportunistic.
They'll readily eat amphibians, frogs, toads, small reptiles
(08:38):
like snakes and lizards, or FairGame 2 + a wide range of
invertebrates, crayfish, shrimp,aquatic insects, and
occasionally, if the chance arises, they might even snatch a
small mammal or a bird. As for hunting techniques, they
are masters of patience. They often use that stand and
wait approach, just standing perfectly still, sometimes for
ages, until prey comes within striking range.
(09:01):
It's like watching a statue cometo life.
I've seen that they barely seem to move.
Exactly. You could almost walk right past
one and then suddenly Wham, thatincredibly fast strike.
That patience is something else.Alternatively, they might stalk
prey very slowly, taking these deliberate, measured steps the
water. Or sometimes they'll even stir
the water with their feet, trying to flesh out hidden
creatures and then quickly nab whatever emerges.
(09:24):
Amazing how they have these different strategies.
So beyond just feeding themselves, what ecological role
do they play? Do they help control other
populations, maybe even pests? Oh, absolutely.
They play a really significant role in population control,
which has broader benefits for the ecosystem.
In aquatic systems, By eating fish and amphibians, they help
(09:44):
keep those populations in balance.
They prevent any one species from becoming too dominant.
That contributes to the overall health and biodiversity of the
wetland. That keeps things in check.
On the terrestrial side or in agricultural areas, they're
actually valuable natural pest controllers.
They eat insects like grasshoppers and beetles, and
also small rodents like mice andvoles, which can cause a lot of
(10:04):
crop damage. Think about the Florida
Everglades. They're crucial for balancing
fish and amphibian numbers there.
Or an Asian rice paddies. They help control insects,
sometimes reducing the need for pesticides.
That's a tangible benefit. So they're not just beautiful,
they're working parts of the ecosystem providing services.
But what about the other side ofthe coin?
What praise on the great Egret? Despite their size and skills,
(10:26):
what makes them vulnerable? Right, even though adult grade
egrets are large, have that sharp bill, and are pretty
vigilant, they aren't completelyimmune.
Raptors, Hawks, eagles, owls could be a threat, especially to
younger birds, but sometimes adults too.
Attacking from above mammals like raccoons, foxes, Bobcats.
They mostly go after eggs and chicks in the nests,
(10:48):
particularly if the nests aren'tcompletely surrounded by water
and are easier to reach and in places where they coexist.
Large reptiles like certain snakes or alligators can
definitely prey on young egrets that are near the water, but
they have defences. Colonial nesting is a huge one.
Safety in numbers. They often nest in these big
colonies, rookeries, usually in trees or shrubs over water.
(11:10):
That makes it really hard for ground predators to get to.
A smart strategy. And their vigilance is key.
If one egret spots danger, it'lloften give an alarm call warning
the whole colony. If a predator gets too close.
There are strong flight allows for a quick escape and they can
also put on aggressive displays,spread their wings, lunge
forward to try and look bigger and more intimidating.
(11:30):
It sounds like survival is really tied to finding that
sweet spot. Good food nearby but also safe
nesting. How directly does food
availability influence where they decide to live or what they
do during the year? Oh, food availability is
absolutely critical. It drives so much of their
behavior and their distribution.It directly influences how they
forage. If food is abundant, they might
(11:51):
spend less time actively hunting, maybe be less
territorial about a feeding spot.
But if resources are scarce, they could become quite fiercely
territorial over a good area. And in terms of their bigger
movements, food availability is the main driver behind those
migration patterns we discussed.Populations in colder places
like southern Canada have to migrate to find areas where the
(12:11):
water stays open and food is accessible all winter.
It also heavily influences theirhabitat selection.
Day-to-day or season to season, they'll move to areas with
reliable water and food. You see, that's when floods
happen. In places like Australia, egrets
might move inland temporarily toexploit newly flooded areas.
And crucially, breeding sites are almost always chosen because
they're near abundant food sources.
(12:33):
Parents need easy access to enough food to feed those
demanding chicks. Fascinating how it all connects.
OK, let's dive into their familylife.
We know about the fancy breedingplumage, but what about the
timing? Does the breeding season vary
much say between here and somewhere tropical?
Yes, absolutely. The breeding season for the
(12:54):
Great Egrid definitely varies depending on where.
They are mostly driven by the local climate and when food is
most abundant. In temperate regions like here
in North America, including southern Canada and the US,
breeding typically gets going inlate spring and runs into early
summer. You might see them starting
nests as early as March or April, but the peak activity is
(13:14):
usually May in June. This timing lines up perfectly
with warmer weather and, critically, the peak
availability of fish and amphibians needed to feed the
checks. Right, gotta time it for the
buffet. Exactly.
But then you go to more tropicalregions like, say, the pants and
all in Brazil. There the breeding season is
more variable. That often lines up with the wet
season, maybe November to March.That's again when seasonal rains
(13:36):
boost food resources. Makes perfect sense.
Timing is crucial when you're raising young, especially with
the fluctuating food supply. OK, walk us through the main
stages of their life cycle, fromthe egg right up to a fully
independent adult. Sure, it's quite a journey.
It starts, of course, with the egg stage.
The female usually lays one to six pale blue-green eggs. 3 or 4
(13:59):
is pretty common, and both parents share incubation duties.
That takes about 23 to 26 days. Then comes the hatchling stage.
When the chicks hatch their altricial.
Basically helpless, blind, can'tregulate their temperature,
totally dependent. Both parents were constantly
feeding them regurgitated food. It's messy, but essential.
(14:19):
This stage can be pretty intense.
There's often strong sibling rivalry.
Stronger chicks might outcompeteweaker ones for food, which can
sadly lead to siblicide mabinty.The stronger ones might push the
weaker ones out, or they just starve.
It's a tough reality, driven by how much food the parents could.
Bring Wow, that's a stark reminder of just how tough
survival is right from the start.
So after that intense beginning,what's next?
(14:40):
Well, after the hatchling stage,they move into the fledgling
stage. This happens around six to seven
weeks after hatching. The young egrets start
developing their flight feathers, get bigger, and begin
venturing out of the nest, practicing flying.
They're pretty clumsy at first. I bet learning to fly those big
wings. Exactly.
Lots of awkward flapping and landings initially, but they
(15:01):
keep at it. They're still dependent on their
parents for food and protection for several more weeks, though,
because they aren't skilled hunters yet.
After that comes the juvenile stage.
Now they're fledged, flying, butstill growing and really honing
those hunting skills. You can tell them apart.
Their language is a bit duller white than the adults.
Their bills are often a dull yellow or grayish, not that
(15:22):
bright yellow, and their legs are usually lighter grayish, not
black. Behaviorally, they're obviously
less experienced hunters. They spend a lot of time
learning, watching adults, practicing.
They're also more social, often hanging out in flocks with other
young egrets. That offers safety and probably
helps them learn from each othertoo.
And then finally, they reached the iconic adult form.
(15:45):
What does the adult stage look like behaviorally, and how do
they actually go about attracting and choosing a mate?
Is it some big elaborate dance? They typically reach the adult
stage at around 2:00 to three years old.
That's when they become sexuallymature.
They get that stunning pure white plumage, the black legs,
the bright yellow bill. And they returned to those
colonial nesting sites, the rookeries, year after year to
(16:07):
breed. And yes, attracting a mate is
quite an elaborate affair, especially during breeding
season. The males really put on a show.
They display those magnificent breeding plumes, the egrets,
very prominently. They perform specific courtship
displays. 1 famous one is the stretch display.
The male stretches his neck way U points his bill to the sky,
fans out his plumes, might spread his wings a bit.
(16:29):
They also do wing flapping, mutual preening and something
called bill clapping. Rapidly opening and closing the
bills make a clicking sound. Sounds noisy.
It can be. Often the male starts building a
basic nest platform, kind of like an invitation.
If a female likes what she sees,she'll join him to finish the
nest. That act of building together
really solidifies their pair bond.
(16:49):
All these mutual behaviors and calls ensure they cooperate well
during nesting and chick rearing, which is obviously very
demanding. That's a lot of effort.
OK, so once that pair bond is solid and the eggs are laid,
what's the parenting like? Are they sharing the load
equally or does one parent do more?
There are definitely proponents of cooperative parenting.
(17:11):
Both the male and female are heavily involved right through
the whole process for nest building.
Often the male gathers most of the sticks and twigs, but the
female usually does the detailedarranging, making it sturdy.
Then they both take turns incubating the eggs, ensuring
they're always warm and protected.
Once the chicks hatch, both parents are busy feeding them
that regurgitated food, and they're both vigilant
(17:34):
protectors, guarding the nest and young against predators like
raccoons or maybe aerial threatslike Hawks.
This shared responsibility is absolutely crucial, especially
thinking back to that brood reduction idea.
If food is scarce, having two parents working might just
ensure at least one chick makes it.
Fledging is gradual. Young start leaving the nests
around six or seven weeks, but they still rely on parents for
(17:56):
food and protection for several more weeks while they learn the
ropes of hunting and independence.
And as they make that slow transition to being on their
own, how do the juveniles reallydiffer from adults beyond just
the colour of their bills and legs?
What are the key behavioral things we might notice if we're
watching them? Yeah, beyond those physical
markers, the duller white dollarbill, lighter legs compared to
(18:16):
the adults, crisp looks, the behavioral differences are quite
striking. Juveniles are just much less
experienced hunters. You'll see them spend a lot more
time learning, practicing, maybemaking clumsy attempts or just
observing adults intently. They're also noticeably more
social. You often find them in flocks
with other youngsters. There's safety in numbers, plus
(18:37):
it's likely a key way they learnby watching their peers.
Their calls are different too. Less varied, maybe softer, often
more focused on those demanding begging calls when they're still
relying on parents. And they're slight, while
capable, is often less graceful than in adults.
They're still mastering those big wings and navigating tricky
landings. It really looks like a learning
phase. It's amazing to think about that
(18:58):
whole journey from helpless hatchling to that graceful,
efficient hunter we see. OK, let's bring this towards the
present and future. What does all this mean for the
Great Egrets? Continued success?
What challenges are they facing right now?
I know that IUCN lists them as Least Concern, but I guess that
doesn't mean everything's perfect.
You're absolutely right, Least Concern is good news reflecting
(19:21):
their large population and wide range, but it definitely doesn't
mean no concern or no threats. While there.
Recovery from the plume trade isa huge conservation win.
Great egrets face several reallysignificant ongoing threats
today that need constant attention.
Probably the biggest one globally is habitat loss and
degradation. Wetlands are still being drained
(19:42):
for agriculture. Urban sprawl, infrastructure
projects and deforestation can also impact them as they need
those trees near water for nesting safely.
So human expansion continues to put pressure on their homes.
What about pollution? They rely so much on water.
Pollution is a major pervasive issue.
Chemical contaminants like pesticides running off farm
fields, or heavy metals like mercury and lead from industrial
(20:05):
sources. These can build up in the food
chain and end up in the E grips that can impact their health,
their reproductive success. Egg shell thinning.
All sorts of problems. Oil spills are devastating too,
obviously coating their feathers, but also through
ingestion when they try to preen.
And we're increasingly worried about plastic pollution.
They can ingest larger pieces, get entangled, or potentially
(20:27):
suffer effects from microplastics accumulating in
their systems. Then there's climate change.
This is a big systemic threat that makes many other problems
worse. Sea level rise can wipe out
coastal wetlands or change the salinity, making them
unsuitable. More frequent and intense storms
can destroy entire nesting colonies.
Changing temperatures affect prey availability, and we're
(20:47):
seeing phenological shifts wherethe timing of breeding or
migration gets out of sync with when their food is available.
That mismatch can be really damaging.
That paints a pretty challengingpicture.
Are there other human factors causing problems?
Yes, direct human disturbance isstill an issue.
Recreational activities like boating, fishing, even just
people getting too close to nesting colonies can cause
(21:09):
stress and lead birds to abandoned nests.
While the large scale plume hunting is gone, illegal
poaching can still happen in some parts of their range.
And invasive species, both plants and animals, can disrupt
things too. Invasive plants might choke out
native vegetation they rely on, while invasive animals might
compete for food or even prey oneggs or chicks.
So yeah, well, at Least Concern is the current status.
(21:31):
It's something that requires ongoing vigilance and action to
maintain. It's a sobering list, but as you
said, their comeback story is a huge +1 of the main conservation
efforts happening now. How do they build on those early
successes? Thankfully, yes, there are
strong ongoing conservation efforts really building on that
historical foundation. Historically, that Migratory
(21:52):
Bird 3D Act of 1918 was pivotal,making plume hunting illegal,
and organizations like the Audubon Societies were crucial
in raising awareness and pushingfor change.
Today, a huge focus is still on habitat protection and
management. That means establishing and
carefully managing wildlife refuges and other protective
areas. Think of places like the
Everglades National Park in Florida, or major wetlands like
(22:14):
Horicon Marsh and Wisconsin, or numerous provincial parks and
conservation areas across southern Canada, including
Quebec, that provide vital breeding and foraging grounds.
And given their global range, are there international efforts
too? Absolutely.
Since many populations migrate across borders, international
cooperation is essential. They benefit from agreements
like the Ramsar Convention, which focuses on conserving
(22:36):
important wetlands globally, andthe Bond Convention, aimed at
protecting migratory species. Beyond formal protection,
continuous monitoring and research are vital.
Scientists track populations, study their ecology, figure out
what works best for conservation.
And public education remains really important, making people
aware of how valuable wetlands are and fostering sense of
(22:57):
stewardship for the egrets and other wildlife that depend on.
So, looking beyond their own survival and conservation,
what's the bigger ecological picture?
What role does the Great Egret play?
What does its presence tell us? Their role is much bigger than
just themselves. It's really foundational for
healthy ecosystems. As we mentioned, they're
considered a key indicator species for wetland health.
(23:18):
Their numbers and breeding success act like a vital sign
for the whole system. If egret populations are
struggling, it often signals wider problems like pollution or
habitat degradation, sometimes before we notice impacts on
other species. As top predators and many
aquatic food webs, they play critical role in regulating prey
populations, fish, amphibians, invertebrates.
(23:40):
By keeping those in check, they prevent anyone group from
becoming too dominant, which helps maintain balance and
benefits aquatic plants too. And historically they're brushed
with extinction due to the plume.
Trade was a catalyst. I fundamentally shifted how
people thought about conservation, highlighted the
need to protect entire ecosystems, not just single
species. It really sparked A broader
movement. Plus, as we touched on, in
(24:01):
agricultural areas, they providethat natural pest control
service, eating insects and rodents, which is a direct
benefit. It's amazing how their own
crisis helped launch the modern conservation movement.
So how do Great Egrets actually contribute to science itself?
Are they in a way helping us understand the natural world
beyond just being an indicator? They absolutely are.
In many ways, they're like natural collaborators for
(24:23):
scientists. Their role as an indicator makes
them invaluable for environmental monitoring,
studying their health, checking for contaminants and their
tissues, tracking their numbers.This helps us assess water
quality and pollutant impacts across large areas.
They contribute hugely to basic ecological studies too.
Watching them helps us understand wetland food webs,
(24:43):
foraging behavior, how differentspecies use habitats,
competition, all sorts of fundamental ecological
questions. And their recovery story is a
powerful case study in conservation biology itself.
It shows what works, protective laws, habitat restoration.
Plus they're very visible. Courtship displays and colonial
nesting make them great subjectsfor behavioral studies teaching
(25:05):
us about avian reproduction and pair bonding, social dynamics in
colonies and with climate change.
Tracking shifts in their migration timing, breeding
success or where they're found can give us crucial early
warnings about how ecosystems are responding to a warming
world. That's a lot of information they
provide just by living their lives.
But what are those lingering questions?
What are the biggest gaps we still need to fill?
(25:26):
Ohe despite everything we know, there are definitely still big
questions, which makes it exciting for future research.
We need more detail on migrationconnectivity.
Knowing precisely which breedingpopulations winter and which are
Pacific areas is vital for targeting conservation
effectively across their full annual cycle.
Getting a more comprehensive picture of climate change
impacts is crucial. How exactly will change in water
(25:49):
levels, temperatures, storm frequency affect their specific
food sources, nesting sites? Long term?
Understanding their genetic diversity across their vast
range is important for ensuring long term resilience.
Are some populations more isolated than others?
We could also use a deeper understanding of their complex
ecological interactions. How do they really fit into food
(26:09):
webs, especially as environmentschange?
What an incredible journey through the life of the great
egret, from their well, just their striking beauty and those
really sophisticated adaptationsfor hunting and surviving, to
their critical role as indicators of wetland health and
that inspiring comeback story. These birds really do embody
resilience and the deep interconnectedness of our
(26:30):
natural world. They remind us that conservation
isn't a one time fix, it's a continuous process and the
health of one species like the egret often truly reflects the
health of an entire ecosystem. Their story is such a powerful
testament to what collective action can achieve, but it's
also a constant call for vigilance.
Isn't. It indeed it is the Great Egrets
journey, you know, from being nearly wiped out to becoming
(26:52):
widespread again, it's a real beacon of hope.
