Somebody bought the ranch today. It was all but dark when I got home and went to fill the feeders, so I'm not sure what species, but gray feathers with white tips tell the tale. Mockingbird? Junco? titmouse? Predator have been a cat, but my guess, from what evidence I could see in the dim light, is that a Sharpie is more likely. Haven't spied a Sharp-Shinned Hawk recently during my limited time to observe, but have often seen them in the yard in the past, including in December. (Still some cats around, but not infested with the 4 neighbor cats anymore. I guess they all died.) I won't be home in daylight until Saturday morning. I'll take a closer look then, in the event there is still enough evidence to draw a conclusion.
