It's not unusual to see Sharp-shinned Hawks in Richmond, but it is unusual to get much of a look at one. Typically they've already shot past your head and disappeared into a hedge or behind a house by the time you've said, "Oh, it's a Sharp...."
To which the person with you replies, "A what?" No wonder they're known as Sharpies. The full name takes too long to spit out.
One of the squirrels (black one) was spooked, and hid beneath a branch atop the fence, doing a squirrel-version thousand-yard stare. The gray one, however, was annoyed, and climbed a lilac to battle(?) the bird.
