The squirrels in the Public Garden are very tame and well fed. They will eat out of your hand and sit on a bench with you.
I sometimes bring them walnuts or pecans. This time I forgot to bring anything, but this squirrel has found a fine nut.
There was a man on a bench nearby feeding a whole group of squirrels, and he had one squirrel sitting on the top of his head. I thought that was going too far!
