This evening as I tended fence an Accipiter sp. that appeared to be a large Coopers Hawk flew past and landed in some Silver Poplars behind the barn. The hawk was about 15 feet in and 25 feet up and did not flush when I got there a few minutes later. The chickens in the barn could see the hawk and none sought cover. All stood up cackling holding tails up vertically and fanned while neck was held erect with hackles held tight. The hawk remained in place even as dog and I tried to get a better view. I hope it is just a larger Coopers. It was a bit on the biggish side so could be someone I seldom see that would be a tougher customer than a Coopers going after juveniles. When hawk left a couple songbirds among trees immediately began singing.
