Amanda Robin (Jacobs lab as undergrad, now completing her UCLA Ph.D. dissertation on squirrel ecology and cognition) and Lucia take on an invited challenge: review the best stuff published on squirrel cognition in the last 5 years (with limited self citation). In 2500 words. For a special issue on “Cognition in the Wild”. We added this graphical abstract.


• Wild squirrels are adapted for a diversity of complex food-hoarding economies.

• Economic decisions in apparently solitary species are driven by social interactions.

• Squirrels exhibit suites of behaviors to reduce their risks of predation and cache loss.
