barheaded goose

The bar-headed goose (Anser indicus) is an Asian goose characterized by a white head with two black bars on its occiput. While most birds fly at lower altitudes, the bar-headed goose is known for its ability to fly at extreme heights, having been observed over the Himalayas. To cope with the limited oxygen at such altitudes, this species can reduce its metabolic rate and strategically avoids flying in strong winds to conserve energy. Geese, in general, are large waterfowl belonging to the family Anatidae and are known for their honking calls and V-formation flight patterns during migration.123
