I found a decapitated House Sparrow near my feeders on Friday. I do not believe it was a cat, as I havn't seen a cat in the 11 months I've lived in this appartment. The likely culprit is a Grackle. I've read about Grackles doing this, for no apparent reason grabbing the occasional House Sparrow and either drowning it in the bird bath or decapitating it and flying off with the head. I've seen the Grackles in my yard regularly lunge toward a House Sparrow, but the smaller bird always gets away. I've been doing some reading on Grackles, and some speculate that they are moving in the direction of birds-of-prey...evolutionarily speaking. That hypothesis attempts to explain their bizarre killing behaviour. How very interesting... --davy russell Burlington, Vermont
