The brown-backed needletail (Hirundapus giganteus), or brown needletail, is a large swift. These birds have very short legs which they use only mainly for clinging to vertical surfaces. They never settle voluntarily on the ground and spend most of their lives in the air, living on the insects they catch in their beaks. These swifts are resident breeders in hill forests in southern India and southeast Asia, extending to the Greater Sunda islands of Indonesia and Palawan in the southern Philippines. They build their nests in rock crevices in cliffs, laying 3-5 eggs. The flight is impressively fast, even compared to other swifts. Wikipedia →
