How do squir­rels find the nuts they buried?

BBC Earth (Asia) - - Science -

It was once thought that they just used their noses to sniff out buried nuts and that the ma­jor­ity were never ac­tu­ally lo­cated. But a 1990 study at Prince­ton Univer­sity showed that squir­rels ac­tu­ally have a good mem­ory and can build a map of the route from one hid­den nut to the next. They still use smell to find the caches of other squir­rels, but they find a lot more of their own by mem­ory. LV



Squir­rels can even sniff out nuts that are buried un­der a layer of snow!
