This morning we had a juvenile - half grown - red tailed hawk visit the backyard. He plunked himself on the top link of the fence as songbirds and collared doves fled in all directions.
He sat there for awhile, waiting for them to return to the seed feeder.
He finally figured out that wasn't going to happen. He fluttered into one of the cottonwoods and hung out there, lurking and waiting to ambush the returnees. He was still there when we left, and there were still no returnees. Contrary to popular opinion, collared doves are not nearly as stupid as they look.
