About These Birds
Bar-headed Goose
Famous as one of the world's highest-flying birds, crossing the Himalayas at altitudes exceeding 7,000 m during migration. Medium-sized, pale grey with two distinctive black bars on the white head. Breeds on high-altitude lakes; winters in South Asian wetlands. Specialized haemoglobin enables high-altitude flight.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
