About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
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.
