I was watching a flock of about 50 starlings and 5 robins around a crabapple tree when all of a sudden there was a great crashing of wings as they all took off in a panic, some nearly knocking themselves out on trees in their haste to get away. Right behind them came this adult sharp-shinned hawk. I think it was a female judging from the size, which was roughly that of a rock pigeon. Anyway, I'll call it she. She then flew into this ash tree and sat for quite awhile, as nearby chickadees were giving their long, "dee-dee-dee-dee-dee-dee..." call indicating their agitation. Later I saw her sitting above the Ash woods feeder, which was, not surprsingly, devoid of birds.
In addition to the above, there were several juncos, a couple of downy woodpeckers, some goldfinches, cardinals, nuthatches, house finches and one house sparrow.
