American Bullfrog (Rana catesbeiana)

I know, this is not a bird. But it grew up in our pond from a tadpole, and has survived for several winters now. Sadly, there is a bird hidden in this picture. Yesterday, my wife saw this fellow with a half dozen feathers hanging out of both sides of its mouth. I do not know what bird it managed to catch, but I assume it is a fairly rare event. I need to watch a bit more closely when the birds go down near the water.
