      About Us

      The large expansive wetland habitats within this montane marsh attract numerous bird species, including waterfowl, shorebirds, and wading birds, including the largest breeding concentration of Sandhill cranes in North America. The Service has documented almost 250 species of birds on the Refuge, of which approximately 100 species known to nest within its boundaries. The Refuge provides significant habitat for breeding waterfowl in the late spring and early summer, and nesting habitat for colonial birds, including a large mixed colony of white-faced ibis and Franklin’s gulls.

      What We Do


      Our Species

      Cranes use Grays Lake as a stopover site during their migration and a segment of the Rocky Mountain Population nests and rears colts along the edges of the marsh. Refuge staff manage habitats to provide for the life requirements of these birds.
