Whooping Crane Migration

Share
Monday, March 25, 2013

Whooping cranes are in the midst of their spring migration and sightings will increase as they make their way through North Dakota over the next several weeks. Anyone seeing these birds as they move through the state is asked to report sightings so the birds can be tracked.

Whoopers stand about five feet tall and have a wingspan of about seven feet from tip to tip. They are bright white with black wing tips, which are visible only when the wings are outspread. In flight they extend their long necks straight forward, while their long, slender legs extend out behind the tail. Whooping cranes typically migrate singly, or in groups of 2-3 birds, and may be associated with sandhill cranes.

Other white birds such as snow geese, swans and egrets are often mistaken for whooping cranes. The most common misidentification is pelicans, because their wingspan is similar and they tuck their pouch in flight, leaving a silhouette similar to a crane when viewed from below.

Anyone sighting whoopers should not disturb them, but record the date, time, location, and the birds' activity. Observers should also look closely for and report colored bands which may occur on one or both legs. Whooping cranes have been marked with colored leg bands to help determine their identity.

Whooping crane sightings should be reported to the U.S. Fish and Wildlife Service office at Lostwood, (701) 848-2466, or Long Lake, (701) 387-4397, the North Dakota Game and Fish Department's main office in Bismarck at (701) 328-6300, or to local game wardens across the state. Reports help biologists locate important whooping crane habitat areas, monitor marked birds, determine survival and population numbers, and identify times and migration routes.
