My wife pronounced the death of one mourning dove to be a good start. They coo a _lot_, early in the morning, right outside our windows.

Heh. Reminds me of an SCA event, more years ago than I want to think about, where my cabin-mates and I were threatening (only partly in jest!) to make whippoorwill stew for dinner. Apparently there was a thriving colony near the cabin, and they went on ALL. NIGHT. LONG.
