Today is Squirrel Appreciation Day! With over 200 species all possessing their own unique squirrel super powers, there is defiantly a lot to appreciate and learn about these cute and sometimes mischievous rodents.
Digital editor Katherine Wu at PBS NOVA interviewed me and other professional squirrel gazers  to narrow down 6 reasons we should all be in awe of these often underestimated rodents.
The food squirrels store is so valuable to them in the winter they do not want to just bury any nut. Squirrels want to ensure they stash away only the best nuts! To do this eastern fox squirrels have worked out a two-step nut evaluation processes.
Rotating the nut between their paws allows them to feel for any cracks or blemishes in the shell. A damaged shell may mean that the item is infested by a bug  or will rot 濫quickly once placed underground and therefore not be edible by the time winter rolls around.
​Handling the food in this way also helps the squirrel either prepare to place the nut in its mouth to carry out step two of the assessment process, the head flick, or to begin eating the item.
The final test the nut has to pass before being stored is the head flick. Once the squirrel has used the paw manipulation maneuver to situate the food in its mouth it will then perform a quick jerking motion with its head. This causes the nut inside the shell to move and bounce off the inner walls of the shell.
The head flick is extremely helpful when it comes to making sure only the best quality food is being stored for the winter. ❄️After all the work it takes to bury a nut for the future it would be a major bummer if it turned out there was no actual food inside the shell or only a really tiny morsel!
