As habitat on breeding and wintering grounds disappears, grassland species have become one of the fastest-declining suites of birds native to North America. Females can mate with several males and have several male-tended nests in one breeding season. Law enforcement is essential to virtually every aspect of wildlife conservation. 1985. The main predators on eggs are coyotes (Canis latrans) and swift fox (Vulpes velox).  Hawks and snakes will kill and eat chicks.  Mortality also occurs from hail, aircraft strikes and overheating. There are at least seven species of plovers found on the continent. Potential predators (e.g. This type of incubation allows for a greater yield of chicks than a monogamous system in which both the male and female tend a single clutch together. STATUS: The mountain plover was proposed for listing in 1999 (Federal Register 64:7587-7601).  In 2003 the mountain plover was removed from the list of species proposed for listing. Most of the birds winter in California in an area with high rates of human population growth. Mountain plover nests are shallow depressions in the ground. In addition, livestock grazing practices that encourage taller grasses and forbs eliminate mountain plover habitat. Plover chicks can run and feed themselves almost immediately after hatching. The Mountain-Prairie Region's Office of Ecological Services (ES) works to restore and protect healthy populations of fish, wildlife, and plants and the environments upon which they depend. The mission of the U.S. They are perhaps the rarest mammals in North America, depending primarily upon prairie dogs for food. Nesting on high, dry plains of western North America, this species is a companion of classic prairie wildlife like bison, pronghorn, and prairie dogs. Mountain Plovers nest only in areas with sparse vegetation or bare ground, such as prairie dog towns. Providing leadership in the conservation of migratory bird habitat through partnerships, grants, and outreach for present and future generations. Other insect prey includes crickets, beetles, and flies. Managed by the U.S. The name “Mountain” Plover is misleading, since this is a species of shortgrass prairies. The U.S. 1987.

Source: Arkive Intended Audience: General Reading Level: Middle School Teacher Section: Yes Mountain Plover - Charadrius montanus Despite its name, the mountain plover is not found in the mountains. But with a great number of prairie dogs eliminated throughout their range, mountain plover habitat has also been severely restricted. It often associates with livestock, which attract and stir up insects. While mountain plovers are commonly found attempting to breed on plowed land in several states, surveys have found that successful nesting is interrupted by subsequent planting and crop growing before nesting is completed. Similar habitats reported in Texas: coastal prairies, alkaline flats, plowed fields, and Bermuda grass fields. BIRD OF THE WEEK: November 25, 2016 SCIENTIFIC NAME: Charadrius montanus POPULATION: Fewer than 20,000 TREND: Declining HABITAT: Breeds on short-grass prairie; winters on plains, fields, and deserts. Because mountain plovers are cryptically colored, they are often overlooked in population surveys, such as the Breeding Bird Survey, so population numbers likely are underestimated. Fish and Wildlife Service is working with The mountain plover often nests on black-tailed prairie dog towns but about 92 percent of areas occupied by prairie dogs have been lost in the last 100 years. This stocky plover breeds in high Arctic zones around the world, and winters on the coasts of six continents. Though their dark-olive-and-black eggs are well-camouflaged, they are nevertheless vulnerable to predators such as coyotes, swift foxes, and ground squirrels. The main predators on eggs are coyotes (Canis latrans) and swift fox (Vulpes velox). It's also nicknamed “Prairie Ghost” for its habit of freezing in place when threatened, blending perfectly into its grassy surroundings. Federal Register 64:7587-7601. 1996.

Their nests are simple scrapes in the ground, and though their eggs are well-camouflaged, they are vulnerable to predators such as coyotes, foxes, and ground squirrels. The understated, elegant sandy plumage of the Mountain Plover blends perfectly with its pale shortgrass and desert surroundings—when alarmed, this bird often simply sits down and disappears. The Mountain Plover is 20–24 cm (8–9.5 inches) long and weighs about 105 grams (3.7 ounces). POPULATION LEVEL: Current population less than 10,000 and has declined by 50 percent since 1966, according to 30 years of Breeding Bird Survey data, which is the highest rate of decline of any other grassland bird. Using the best available science, ES personnel work with Federal, State, Tribal, local, and non-profit stakeholders, as well as private land owners, to avoid, minimize, and mitigate threats to our Nation's natural resources. The majority of nest mortality on agricultural fields was attributed to both agricultural practices and predators for all years of the study, while the mortality on rangelands was attributed to predators . ).  The Academy of Natural Sciences, Philadelphia, and the American Ornithologists' Union, Washington, DC. Mountain plover status on their current breeding range-special emphasis on the birds on and near the Antelope Coal Mine in the souther Powder River Basin, Converse County, Wyoming. Johnsgard, P.A. On the breeding grounds, Mountain Plover conservation depends on the protection of suitable nesting habitat and nest sites as well as prairie dog protection. United States Fish and Wildlife Service. Pesticides may also affect the population of the bird. REPRODUCTION AND DEVELOPMENT: Mountain plovers nest in sparsely vegetated habitats such as short-grass prairies, sage brush, and semi-desert but also will nest on fallow and recently plowed ground. 211 (A. Poole and F. Gill, eds. The remainder of potential habitat on this site is poor to good, but should be surveyed in the spring for Mountain Plovers.
