Mountain plover

Unlike most plovers, it is usually not found near bodies of water or even on wet soil; it prefers dry habitat with short grass (usually due to grazing) and bare ground.

In Medieval England some migratory birds became known as plovers because they returned to their breeding grounds each spring with rain.

Around late July, mountain plovers leave their breeding range for a period of post-breeding wandering around the southern Great Plains.

Mountain plovers nest on bare ground in early spring (April in northern Colorado).

Plovers usually select a breeding range that they share with bison and black tailed prairie dogs.

It is believed that plovers like to nest on bare soil because they blend into the land hiding them from birds that may prey on them and the short vegetation allows them to easily detect predators on the ground.

These conditions are preferred because of the climate's effect on the eggs directly, changes in predatory behavior, or changes in vegetation that can affect the mortality rates of parents.

Increase in soil moisture may the environment of bare grounds and short grass that prairie birds thrive in.

Their breeding season extends over the summer months and ends some time around late July or early August.

It has been found that eggs laid during a time of drought tend to be larger providing the incubating chick with more nourishment and so a greater chance at survival.

This type of incubation suits the mountain plover well and allows for a greater yield of chicks compared to similar species of birds in which both the male and female tend a single clutch together.

If the eggs survive various dangers, especially such predators as coyotes, snakes, and swift foxes, they hatch in 28 to 31 days, and the hatchlings leave the nest within a few hours.

In the next two or three days, the family usually moves one to two kilometers from the nest site to a good feeding area, often near a water tank for livestock.

In March 2009, a multi-agency report, the first of its kind, issued by the Cornell University Lab of Ornithology in conjunction with federal agencies and other organizations, indicated that the mountain plover is one of the birds showing serious declines in population.

Fish and Wildlife Service published a proposed rule to list the mountain plover as threatened under the Endangered Species Act.

[4] A 2005 report details that in a study conducted by Stephen J Dinsmore, Gary C White, and Fritz L Knopf, the populations of mountain plovers and prairie dogs in southern Phillips County in north-central Montana were observed in the effort to provide clues about the ecosystem and mountain plover preservation.

Other proposed plans of preservation include protecting remaining breeding and wintering habitats, and stopping the conversion of grasslands for agricultural purposes.
