Yeah I know. It's outside my window every morning.

My blue jays still do that sometimes, but at least one is even smarter than I thought. They used to perch above the sunflower seed feeders and mimic a Red-Tailed. The small birds would all scatter, and the mimic jay would swoop down and eat. After a while, though, the little birds started to figure it out; they'd hear the "hawk", but only a few would leave. One day, I was sitting outside on the patio, and heard the oddest sound; almost like a Cooper's hawk, but as if it had a head cold. I live right next to the woods, so Cooper's are common, and you can bet the birds know it, and respect the kik-kik-kik. They heard that, and they were gone. I heard them flying away en masse and looked down toward the feeders to see...a single blue jay, parked in one of the tray feeders, happily munching sunflower seeds.
