Apus is one of twelve southern constellations mapped by Dutch explorer Frederick de Houtman and navigator Pieter Dirkszoon Keyser in 1595-97, and formed into constellations by Dutch astronomer Petrus Plancius. Plancius called it Paradysvogel Apis Indica, "Paradysvogel" meaning "Bird of Paradise", and "Apis" meaning "footless" (early specimens of the birds having had their feet and wings removed); this was shortened to Apis Indica by Bayer, and subsequent atlases used various corruptions of the name.
