Winter brings a familiar rhythm to Bosque del Apache National Wildlife Refuge in New Mexico. The cranes arrive, wetlands fill with birds, and this area becomes a hub for seasonal wildlife. Established in 1939, the 57,331-acre sanctuary was created to provide a protected stopover for migrating waterfowl. Its wetlands, fields and waterways now support wildlife throughout the year. Sandhill cranes, seen in today's image, are especially associated with the refuge during winter.

These cranes typically begin arriving in late October and remain throughout the winter. At night, they roost in shallow water before heading to nearby fields around sunrise to feed. The refuge is an important wintering ground for the Rocky Mountain population of sandhill cranes, which migrates through the Middle Rio Grande Valley. Other seasonal visitors include snow geese, Ross's geese, northern pintails, northern shovelers, hawks and eagles. Mammals such as mule deer, coyotes and jackrabbits also inhabit the refuge, while its habitats support threatened and endangered species.
