Little nasties

Is it me, or are the squirrels this summer especially nasty? Every day they're digging in the flower beds, making holes the size of a fist and tossing mulch everywhere. If I didn't know better, I'd think the garden was home to prairie dogs.

The other day two birds were communing in the bird bath and a squirrel began stalking them. He looked like a cat about to pounce. When did this behavior show up in the DNA of a squirrel?

Maybe the shrinking economy has made them mean. Anger management classes could be in order.
