The Bar-headed Goose. . The Bar-headed Goose migrates over the Himalayas to spend the winter in India, Assam, Northern Burma and the wetlands of Pakistan. The Bar-headed Goose is one of the worlds highest flying birds, having been seen at up to 10175 m (33,382 feet). It has a slightly larger wing area for its weight than other geese and it is believed this helps the goose to fly so high. The summer habitat is high altitude lakes where the bird grazes on short grass. The species has been reported as migrating south from China, Kazakhstan, Mongolia and Russia before crossing the Himalaya. The bird has come to the attention of medical science in recent years as having been an early victim of the H5N1 virus, HPAI (highly pathogenic avian influenza), at Qinghai. It suffers predation from crows, foxes, ravens, sea eagles, gulls and others. The total population may, however, be increasing[citation needed], but it is complex to assess population trends as this species occurs over more than 2.5 million square kilometres.
