Squirrels are just the best. If anyone goes to visit Taiwan - which I certainly recommend as strongly as possible - there's a park in the capital Taipei called 2/28 Memorial Peace Park (二二八和平紀念公園).
There are these gorgeous squirrels with red bellies that will eat nuts right out of your hand. They'll come up to you, take a nut and then run off about midway up a tree. Using their back legs to hold onto the bark, they dangle head-down against the trunk, eating with their front paws. Then you look around and all the trees have these vertical furry tree-slug looking squirrels dangling against them. Just cuting it up cutefully.
Red-bellied plumpers is what my wife and I called them. They're just the best.

There's a piece from stanford and harvard business review (of all places). I couldn't find the original studies on academia.edu after a couple minutes of searching but maybe you'll have better luck. I think there's a behind the bastards podcast episode about it too.
