The dark-rumped swift is a slim, dark aerial bird with narrow sickle-shaped wings, a forked tail and a darker rump than similar pale-rumped swifts. It has a fragmented range in the Himalayas and northern mainland Southeast Asia, using montane forest and cliffs. Birds feed entirely on small insects caught in flight and nest colonially on sheltered rock faces or cave walls (Wikipedia, general species account). It is Nationally Near Threatened (Thailand Red Data 2025).
