Brains in the Branches: how chickadees outsmart our harsh winters
Published in Ecology & Evolution and Behavioural Sciences & Psychology
You’ve probably heard of a chickadee, if only from Christmas cards, but they have fascinated scientists for a particular reason: this tiny little bird has a crazy capacity for memory.
We’re up in the eastern Sierra Nevadas, one pass over from where the infamous Donner party got trapped trying to cross the mountain pass. The environment up here is beautiful, but not kind– not only is the air thin from how high up we are, but the summers are blisteringly hot and the winters are bone-chillingly cold, with up to fifteen feet of snow on the ground. Yet somehow, these little birds thrive.
But how? Turns out, they hide and recover tens of thousands of seeds across the forest to eat over the winter, making them a prime candidate to test theories on how the brain works and how specialised brain tasks– like crazy spatial cognition– have evolved.
Noah Camuso, a journalist and screenwriter from Oregon, and Ai Ana Richmond, a PhD student at the University of Nevada Reno and the first author of the paper, have made this video on the findings of a recent paper on cognitive flexibility in these charming little birds. Feel free to watch along to learn more– and maybe feel a little silly the next time you forget your keys!

Social Cognition in a Human World
As humanity exploits and reshapes the environment to accommodate for development and population growth demands, animals need to adapt to these human-induced rapid environmental changes and increased likelihood of human interactions, but also to deal with increased competition due to higher densities of conspecifics and heterospecifics in the ever-dwindling suitable habitats. And yet, certain species appear to adjust more successfully to these challenges than do others, finding ways to thrive amidst these anthropogenic changes. Examples of social cognitive abilities that allow animals to exploit this human-dominated world include individual recognition and communication, information gathering through individual and social learning and behavioural reading (in both conspecifics and heterospecifics, including humans), and flexibility in social behaviour. The aim of this Special Collection is to explore how animals adapt - or fail to adapt - to these changes across a wide range of species, approaches, and disciplines.
For more details, please read our submission guidelines. Articles will undergo the journal’s standard peer-review process and are subject to all the journal’s standard policies. Articles will be added to the Collection as they are published. The Editors have no competing interests with the submissions which they handle through the peer-review process. The peer-review of any submissions for which the Editors have competing interests is handled by another Editorial Board Member who has no competing interests.
