The Prairie, by the way, is beautiful. Take some time to enjoy the flowers and grasses. A very good edge habitat is the Forest Edge loop on the far east side. It is un-marked on the map, but is the service road loop just north of parking 13. A slow drive or walk along the main road from parking 4 to parking 7 can turn up a nice diversity of field and savanna birds.
Bluebirds are a lock.
Tufted Titmice have been reported from the far northeastern corner - in the area of the Big Rock Trail. Never seen, just heard. There are several pairs of Great Horned Owls at the Arb. Spruce Hill is as good a spot as any. Cooper's Hawks are a reasonable expectation.
