The bar-headed goose is a migratory bird known for its remarkable ability to fly at high altitudes. It breeds in the central Asian region, particularly in Tibet, and migrates to India during the winter months. This species is easily identifiable by its distinctive gray and white plumage, along with two black bars on its head. These geese are well-adapted to their high-altitude environment, with specialized lungs and a unique hemoglobin structure that allows them to efficiently use oxygen. They primarily feed on grasses and aquatic plants, often foraging in wetlands and fields during their migration.
