I love to watch them try to get to the bird food given the squirrel baffle that is protecting it. And the interplay between the squirrels and the birds, and my cats -- it is as good as a choreographed Keystone Kops comedy.
Until this time of year, when the neighbor's tree bears its mandarin oranges. Little buggers use the fence between us to get to the oranges, sit on the fence, peel the oranges, and toss the rinds into MY yard, not the neighbor's. Pest, indeed.
