I have noticed suspicious squirrel activity around the trees in front of my office building: chattering, an aggressive flicking of tails, digging around in the pine straw around the trees, chasing each other around the tree trunks. They're trying to act like they're nut-hunting, but maybe that's just what they want us to think.
I don't know about you, but I'm going to keep a close eye on those critters. They may look cute, but.........
Usually squirrels are gray or brown, but I've noticed that my apartment complex has a whole bunch of dark black squirrels. Are these mutant squirrels? Are they immigrant squirrels?
