The Mangaia Salangan ( Collocalia manuoi ) is an extinct species of bird from the Salangan tribe . The type epithet is derived from the Polynesian words "manu" (= wild birds) and "oi" (= fluttering through the air).
The Mangaia Salangan is only known from subfossil bone material that was brought to light in 1997 by David William Steadman on the Cook Island Mangaia . The holotype consists of a right coracoid, the paratypes of two right and one left complete coracoid , a complete carpometacarpus , an almost complete finger bone and a right tibiotarsus in which the proximal end is missing. Three coracoids have lengths of 8.07, 8.0 and 8.2 mm. The carpometacarpus measures 13.44 mm and the finger bone 6.69 mm.
The bones are larger than those from the recent Atiusalangane ( Aerodramus sawtelli ) found on the neighboring island of Atiu . According to Steadman, despite the close proximity of the home islands, there is no close relationship between the two taxa from an osteological point of view.
The geological layers in which the material was discovered are dated from 1390 to 1470.
According to the current system of sailing birds, the Mangaia Salangane probably belongs to the genus Aerodramus .
