The Alpine swift (Tachymarptis melba) or Apus melba, is a species of swift. Alpine swifts breed in mountains from southern Europe to the Himalaya. Like common swifts, they are strongly migratory, and winter much further south in southern Africa.
Swifts have very short legs which are used for clinging to vertical surfaces. They never settle voluntarily on the ground, spending most of their lives in the air living on the insects they catch in their beaks. Alpine swift are able to stay aloft in the air for up to seven months at a time, even drinking water "on the wing". Their vital physiological processes, including sleep, can be performed while in continuous flight.
Alpine swifts spend most of their lives in the air, living on the insects they catch in their beaks. They drink on the wing, but roost on vertical cliffs or walls. A study published in 2013 showed Alpine swifts can spend over six months flying without having to land. All vital physiological processes, including sleep, can be performed while on air.
In 2011, Felix Liechti and his colleagues at the Swiss Ornithological Institute attached electronic tags that log movement to six alpine swifts and it was discovered that the birds could stay aloft in the air for more than 200 days straight. From Wikipedia, the free encyclopedia
