Identificazione
Chunky bird with broad, triangular wings and short, decurved bill. Dark brownish-gray plumage, lacking white in primaries (compare larger Dusky Woodswallow). Tail black with white tip broken by black at the center. Grayish underwings contrast with dark belly in flight, though not to the degree seen in other woodswallows. Usually in small flocks, foraging high above rocky cliffs and gorges, or huddled together when perched.
