Titmouse was screaming bloody murder outside the window, so I had to check and see if one of the neighborhood cats was stalking the feeder. Nope: it was OH THE HORROR a male ruby-throated hummingbird minding its own business at the hummingbird feeder. By the time I got the camera he was gone, and the titmouse could quit hopping around in panic and come down to the suet feeder. Lookit this idiot.
