The Mountain Plover (Charadrius montanus) is an uncommon shorebird of conservation concern
that breeds in the Great Plains and the Great Basin.
In my study area in Montana they nest almost entirely on Black-tailed Prairie Dog colonies.
On June 29, 2010 the U.S. Fish and Wildlife Service reinstated a proposal to list the Mountain Plover as a threatened species under the Endangered Species Act.
In May 2011 the Fish and Wildlife Service determined that this species is not threatened or endangered throughout all or a significant portion of its range.
The eggs of Mountain Plovers vary in size, shape, and color.
Other North American members of the genus Charadrius include:
the Semipalmated Plover (C. semipalmatus), Wilson's Plover (C. wilsonia), the Killdeer (C. vociferus),
the Piping Plover (C. melodus), and the Snowy Plover (C. nivosus).
Non-breeding Mountain Plovers can be confused with non-breeding members of the genus Pluvialis:
the American Golden Plover (P. dominica) and the Black-bellied Plover (P. squatarola).
