The 'Redwing' looks something like an American Robin (same Genus name)
Here in Virginia, our Pyracantha (Firethorn) bushes are regularly assaulted by Cedar Waxwings on their Southern migration. Last October, I was in my study at St. Paul's, when I heard a commotion outside. When I opened the door, I saw about 75 Waxwings on the bush, and in 10 minutes they had stripped it bare. Five minutes later, there was not a bird in sight.
