The Whooping Crane (Grus americana) is a very large crane. It is the tallest North American bird and the only crane species found solely in North America. Adults are white; they have a red crown and a long, dark, pointed bill. They have long dark legs which trail behind in flight and a long neck that is kept straight in flight. Black wing tips can be seen in flight. Immature birds are pale brown. Their breeding habitat is muskeg; the only known nesting location is Wood Buffalo National Park in Canada and the surrounding area. They nest on the ground, usually on a raised area in a marsh. The female lays 1 to 3 eggs. Both parents feed the young. Usually no more than one young bird survives in a season. Loads more on Wikipedia (link below) - good luck
