The Northern Rough-winged Swallow is one of many members of the swallow family. Swallows are small aerial songbirds with long, pointed wings. The Rough-winged Swallows feed on flying insects captured in graceful swooping flight. They tend to be most active and noisiest at dawn and at dusk. As local, but not common breeding birds, they arrive mid-April and chicks hatch typically in June. The Northern Rough-winged Swallow has brown upperparts and light brownish gray underparts. This swallow was recently seen on a dock in Woods Hole.
