Revision History. Originally Appeared in. Birds of North America logo. Content Partner. Chicks are rust-colored when they hatch; at about four months, chicks' feathers begin turning white. By the end of their first migration, they are brown and white, and as they enter their first spring, their plumage is white with black wing tips. The hatchlings will stay with their parents throughout their first winter, and separate when the spring migration begins.
The sub-adults form groups and travel together. Cranes live in family groups made up of the parents and 1 or 2 offspring. In the spring, whooping cranes perform courtship displays loud calling, wing flapping, leaps in the air as they get ready to migrate to their breeding grounds.
Their diet consists of blue crabs, clams, frogs, minnows, rodents, small birds, and berries. Early counts showed birds left the wintering grounds on the Texas coast with smaller populations in New Mexico and Florida. Whooping cranes winter on the Aransas National Wildlife Refuge's 22, acres of salt flats and marshes. The area's coastal prairie rolls gently here and is dotted with swales and ponds. Although they breed in Canada during the summer months, whooping cranes migrate to Texas' coastal plains near Rockport, in and around Aransas National Wildlife Refuge, from November through March.
