I live in Florida where I think there are as many squirrels as there are people and cars! I've had to learn to just live with them because nothing I've tried seems to deter them. They constantly raid the birdfeeders, it doesn't matter if I add hot pepper flakes to the seed or not. They also eat the suet in the suet feeders, even the hot peppery type that squirrels are not supposed to like! I have three birdbaths in the yard and one shallow water bowl on the ground but I rarely see a squirrel at a water station. Whenever I take the dogs out into the backyard, the squirrels usually hie tail it up into the trees and sit there chattering away until we go back inside.
The hickory trees have a lot of fruit at this time of year and the squirrels are lazing about along branches, eating the Hickory nuts. I was outside with the dogs a few minutes ago and had my camera with me. I heard the distinct (and rather loud noise) of squirrels chewing away on those hard nuts and spotted at least four squirrels in different trees enjoying their dinner; here's one lazy guy or gal, stretched out along a branch, munching away on a hickory nut:
I do enjoy the squirrels antics, especially the youngsters when they chase each other up, down and around, from one tree to another! The photos below are from last year; there were 4 or 5 babies chasing each other down one tree and across the backyard, where they'd run up another. When I went out with my camera, they scattered every which way but these two stopped at the base of one of the trees and then as I got closer, they ran up and paused in the crook of the tree, peeking out:
