Heard a chirp at my window ledge just now, looked up and saw that the feeder was empty and a house finch was sitting on the power line. I am fairly certain she was trying to get my attention, as there was nothing else around to chirp at, and as soon as I’d refilled the feeder and it stopped swinging she was back and munching away. I guess this means someone’s at least half domesticated, but I’m not sure who.
