Endangered Status  The Mississippi Sandhill Crane, a subspecies of the Sandhill Crane, is on the U.S. Endangered Species List. It is classified as endangered in Mississippi. Apparently the Sandhill Crane was always more numerous than the larger Whooping Crane, and the fact that it breeds mostly in the remote Arctic has saved it from the fate of its relative. But it is sensitive to human disturbance, and the draining of marshes has reduced nesting populations in the United States. The Mississippi subspecies declined in the mid-20th century when its preferred savannah habitat was planted over with slash pines. Commercial and residential development, the building of highways, pollution, and other factors have caused further deterioration to the habitat. Most of the current crane population and its habitat are protected in the Mississippi Sandhill Crane National Wildlife Refuge. The Grand Bay National Wildlife Refuge to the southeast may be able to sustain a second population of cranes.

Habitat  Very locally common. Vast majority of population nests on remote tundra or expansive northern wetlands, and winters in wetland areas with adjacent farmland in southern U.S. and Mexico. Small population (4,000-5,000 birds) is resident in Florida, numbers boosted in winter by migrants.

Observation Tips  At traditional migration staging areas and winter roosts, the massive numbers of Sandhill Cranes provide one of the greatest wildlife spectacles.

Range  Alaska, Eastern Canada, Mid-Atlantic, Plains, Southeast, Rocky Mountains, Great Lakes, California, Florida, Texas, New England, Western Canada, Southwest, Northwest

Discussion  Large and almost unmistakable bird with a stately posture and gait. Confusion with Great Blue Heron is possible, but note differences in plumage, structure, and head markings. Outside breeding season, Sandhill is invariably seen in large flocks, whereas Great Blue is usually solitary. In flight, Sandhill holds head and neck outstretched, while Great Blue has neck hunched into an "S" shape. Seen from below in flight, note mainly pale flight feathers. Arctic nesters are appreciably smaller and shorter-billed than southern breeders. Sexes are similar.
