This small, dark swift measures 10 cm (3.9 in) long. It is sooty-brown above, slightly lighter below.[2]

Its natural habitats are the island's fernlands and mixed horticultural areas over which it feeds, and in makatea limestone caves within which it nests.[2] The species is known on Atiu as kopeka.

Unlike all other swiftlets, it echolocates only through single clicks, rather than a mix of single- and double clicks.[3]
