The group of doves that visit my birdfeeder now number in the mid-twenties, and periodically I find a partly eaten dove in the yard, or a lot of feathers indicating the demise of a dove. This one, below the bird-feeder, was not cold, even though it is a cold day after a cold night, so it has died this morning. I suspect a cat is the cause, but not a hungry one, else it would have eaten much of the bird.
