He followed and found the hawk perched near the top of a tall cypress tree, in plain sight. The bird was in his claw, one wing drooped down. He milled about on the ground trying to identify its prey.

He tossed it on the lawn where the hawk could see it if he was still hungry. That evening one of our graduate students in Biology told me that he had seen virtually the same scene a year ago -- Cooper Hawk with a jaysen. White-winged doves were cooing on the roof of the Engineering Building. Mar. 25, 1979 On several recent occasions I have watched groups of female boat-tailed grackles foraging on lawns. They work along in tandem, a few feet apart, and are constantly alert to where the other birds in the group are headed. I couldn't see any of them actually catch anything but they were sure looking.
