The World Record of ‘highest flying birds’ has been achieved by Bar-headed Goose (Anser indicus) from Central Asia.

The Bar Headed Goose is recorded to have flown to an amazing height of 10175 m (33,382 feet). Thus they can easily cross the highest mountain in the world, Mount Everest which has an altitude of 8,848 m (29,028 feet). the Bar-headed goose reaches the extra-ordinary height by smartly flapping their wings. This is the reason why these geese don’t depend on the tail-wind on the Himalayan range; in fact they deny the winds and starts climbing up high altitude when the wind blows out. The bird’s body is specially made to meet this exceptional capability. More red-blood cells and more capillaries than normal birds deliver their muscles more oxygen than others.
