The volcano swiftlet was formerly considered conspecific with the Himalayan swiftlet. It is 13–14 cm long and dark grey with a conspicuous brown rump band, which is less defined in young birds. It is easily heard thanks to a distinctive clicking call. Nothing is known about its diet (Wikipedia, general species account).
