Stepping on snakes for science, and crows that count out loud

A roundup of online news stories featuring animals, and researchers get crows to “count” to four   This week’s show is all animals all the time. First, Online News Editor Dave Grimm joins host Sarah Crespi to discuss stepping on venomous snakes for science, hunting ice age cave bears, and demolishing lizardlike buildings.   Next, producer Kevin McLean talks with Diana Liao, a postdoctoral researcher at the University of Tübingen, about teaching crows to count out loud. They discuss the complexity of this behavior and how, like the famous band, these counting corvids have all the right vocal skills to do it.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Kevin McLean; David Grimm   Episode page: https://www.science.org/doi/10.1126/science.ztje4j6 Learn more about your ad choices.
