While taking a walk here in Venice, Fl, a Cooper's Hawk flew into a tree, glared at use, turned away and swooped down to the ground grabbed a lizard and chomped away. People were walking on the sidewalk not 5 feet away but the hawk ignored them all. Coopers and Sharp-Shinned Hawks are fearless killers, eating many small birds. They love hanging around a bird feeder. It's like a cafeteria to them.
