Highest-Flying Birds
The highest altitudes at which birds have been recorded flying, in metres. Rüppell's vulture holds the record at 11,300 m - higher than a cruising airliner - after one collided with an aircraft over West Africa in 1973.
About This Dataset
Highest-Flying BirdsRüppell's vulture (11,300 m) flies higher than any other bird on record, cruising at altitudes where jetliners fly and oxygen is less than a quarter of sea-level values - a feat enabled by a special haemoglobin that binds oxygen far more efficiently. The common crane (10,000 m), bar-headed goose (8,800 m) and whooper swan (8,200 m) follow, all famed for crossing the world's highest mountain ranges during migration. The bearded vulture (7,300 m) and mallard (6,400 m) round out the list. The pattern splits into two groups: soaring scavengers like the vultures that ride thermals to extreme heights while searching for carrion, and powerful migratory waterfowl that climb over the Himalayas. Both defy the thin, frigid air that would render most animals unconscious.
