About These Birds
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
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.
