The Cooper's Hawk on the fence (just left of the small tree in the photo) screams at the plastic owl, attached to the fence near the gate (right of the tree). The apathetic owl does not respond. The hawk screams again, from the fence and then from above in a large oak. The owl, unflappable as always, is silent.
Enraged, the hawk attacks! At this point, Chunk wants a piece of the action, and yanks the leash so hard, my camera sails into the street—note the blurry photo. With the dog barking hysterically and me running after the camera, the hawk flip-flops away. Serene on his throne, the plastic owl remains.
The next morning I had breakfast out on the patio with my camera (it survived the crash). I noticed a flurry of bird calls. The crows were crowing, the jays were jaying, and the grackles were grackling. And no wonder! A Cooper's Hawk—perhaps the same one—was perched on the girder of the nearby water tower.
The crows gave him the same treatment he had given the owl the evening before, but Cooper's was not so cool-headed.
He dashed away after his tormentors, but they had a pretty good lead. The neighborhood was quiet again.
