Aha! That's why this squirrel can get into the squirrel-proof bird feeders -- it's only half the size of the grey squirrels around here. And then there's that chestnut streak down its back -- are any of you squirrel specialists? Can anyone tell me if this is something worth writing to Cornell about?
(A few years ago I found a strange bug on the bathtub, sent a picture to Cornell and was told I'd made the first report from Monroe County of the invading Stink Bug.)
So do squirrels ever mate with chipmunks? I guess not, but that's sort of the size of this free-loader. Any information appreciated.
