Dusky Crag-Martin Ptyonoprogne concolor

An overall dark brown swallow with paler underparts. It has a square tail with a white spot on each tail feather, making a white speckled band of sorts. Young birds have paler underparts. Mostly seen flying in pairs or small flocks along cliffs, but sometimes also near tall buildings. Flight action generally slower than Barn Swallow’s, but can wheel and loop at quick speed.
