Hi All, Yesterday, I heard birds in the backyard giving danger calls. When I went to investigate I found on a dead branch of an apple tree about 12 feet off the ground a Hooded Warbler, a Worm-eating Warbler, two Titmice, a Carolina Chickadee, a Carolina Wren and a female Cardinal. They were all acting very upset and moving constantly in about a 4 foot area of sparse dead twigs on the dead branch. Since I had seen a Rat Snake in the area a few days before I was sure that must be what they were upset about. However, when I looked closely I couldn't see any signs of a predator. They were concentrating their activities in this one area and there was nothing there. I even searched the ground underneath and there was nothing beneath the branch. There were no leaves at all on the branch, and it was only about as thick as my wrist at the widest part; the twigs weren't dense enough to hide a snake. After a few minutes of this frenzied activity the group began to disperse. I continued to search but found nothing. It left me scratching my head and wondering what was going on.
