A sharp-shined hawk visited my feeders last week. I suspect it has been noting the chickadees, finches and nuthatches that come every day. I have to assume he figured that a feeder is a feeder and he can have a bit of bird for breakfast. It stayed long enough for a photo, but I didn't see it catch anything. The books say that this species like to hangout in low bushes and small trees waiting for a meal.
