'''Habitat:''' North America and Asia; distributed throughout North America, extending into Cuba and far northeastern Siberia. The three migratory subspecies (Lesser, Greater and Canadian) are distributed across a broad breeding range in the northern U.S. and Canada as well as eastern Siberia, with wintering grounds in the southern United States and northern Mexico. The three non-migratory subspecies (Mississippi, Cuban, and Florida) have restricted ranges in the southern United States and Cuba. Found in open fresh water wetlands, but the different subspecies utilize habitats that range from bogs, sedge meadows, and fens to open grasslands, pine savannas, and cultivated lands. Sandhill Cranes occur at their highest breeding density in habitats that contain open sedge meadows in wetlands that are adjacent to short vegetation in uplands.

'''Status:''' Least Concern. This species has an extremely large range and has a population between 520, 000 to 530,000.  Some subspecies are endangered. Loss and degradation of riverine and wetland ecosystems are the most important threats to Sandhill Crane populations. For the migratory populations, this is of greatest concern in staging and wintering areas. Spring staging areas along the Platte River in Nebraska are of special concern because of their importance to the migratory subspecies and the development pressures facing this region. Approximately 80% of all Sandhill Cranes utilize a 75-mile stretch of the Platte River in spring migration. Elsewhere, small breeding populations can face disproportionate mortality on fall staging areas due to over-hunting. Residential and commercial development pressures facing lands occupied by birds belonging to non-migratory subspecies in Mississippi, Florida, and Cuba also pose significant threats.
