About These Birds
อินทรีหัวขาว
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
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.
