The bar-headed goose (Anser indicus) of Central Asia migrates through the Himalayas mountain range at an altitude of 10,175 m (33,380 ft) – a height at which the air is so thin not even helicopters can fly. The goose´s large wing area and efficient oxygen uptake means that it can fly higher than other birds of the same size, and its unrivalled strength allows it to cope with headwinds that would knock other birds out of the sky.
The bar-headed goose migrates to avoid monsoon summers and freezing winters.
