I don't know what these little buggers are so upset about. If I said these kinds of things in public, I might be locked up. Are they just territorial, or what? I'm just sayin'. I see them outside the window of my semi-new office, which faces out on green space. They take flying leaps, scurry up and down the cedars, and - we can't call it chattering or scolding. It's plain nasty, is what it is. The tail-flapping is definitely very macho. So do females do this too, in a display of machisma? Are they defending, what, the nut in their mouth(s), the nut buried under the tree, the tree itself? Or are they just nuts? Are they scaring away imaginary predators? Or just racketing off for the hell of it?
I'm just askin'.
