Nest lining (including pebbles, grass, rootlets, chips of cow manure) added mostly during incubation. 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. 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. of Mountain Plover nests as a function of the sex of the incubating adult, nest age, year, linear and quadratic time trends, and two weather covariates (maximum daily temperature and daily precipitation) during a six-year study (1995–2000). Most Plovers nest on the ground, but their incubation periods and fledging rates vary from species to species. On the breeding grounds, Mountain Plover conservation depends on the protection of suitable nesting habitat and nest sites as well as prairie dog protection. Data collection. Their breeding season extends over the summer months and ends some time around late July or early August. Most nest and chick predation is done primarily by mammals and reptilians. Its calls are variable, often low-pitched trilled or gurgling whistles. 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. However, concerning conservation, a large portion of the overall plover population breeds near the northern limit of their range in Montana, and it would be wise to make this area a conservation priority. This information is used to ensure that we give you the best experience on our website. Plovers usually select a breeding range that they share with bison and black tailed prairie dogs. As habitat on breeding and wintering grounds disappears, grassland species have become one of the fastest-declining suites of birds native to North America. The mountain plover is 8 to 9.5 inches (20 to 24 cm) long and weighs about 3.7 ounces (105 grams). Agricultural fields provide ideal habitat for them, as long as their nests are not accidentally tilled. quality to some degree. She will lay up to four eggs over the course of a week. Following point counts we returned to colonies where Mountain Plovers had been detected, either that year or historically, and conducted nest searches at these sites following the method of Dinsmore et al. Here, thanks to the efforts of our partner Pronatura Noreste, ranchers in Mexico are now strategically moving cattle from pasture to pasture, mimicking natural processes that maintain habitat for grassland birds. Little is known about their movements at this time, although they are regularly seen around Walsh, Colorado and on sod farms in central New Mexico. Studies in Colorado found that mountain plovers need at least 70 acres to raise a brood, although sometimes the boundaries of brooding areas overlap. This would result in a greater reproductive success for the female but there is a high energy cost on the female laying so many eggs and so it is more common for a female to lay only two clutches. The name “Mountain” Plover is misleading, since this is a species of shortgrass prairies. Nesting areas are associated with bare ground (~30%) and flat or slight slope (~ 5%). Like other plovers, including the Piping Plover, the Mountain Plover feeds on the ground. Fish and Wildlife Service press release on the mountain plover's conservation status, https://en.wikipedia.org/w/index.php?title=Mountain_plover&oldid=988493365, Articles lacking in-text citations from March 2016, Creative Commons Attribution-ShareAlike License. Knopf, Fritz L. (1997): A Closer Look: Mountain Plover. Childers T, Dinsmore S. 2008. It feeds mostly on insects and other small arthropods. 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. The population of plovers in Wyoming is lower than that of other states, but Wyoming's population of mountain plovers and mostly intact expanses of grazed rangeland will probably become much more important in the coming years as urban and agricultural development continues in contiguous states. [2] The population of mountain plovers is in decline because of cultivation, urbanization, and over-grazing of their living space. Mountain Plovers forage through grasses and recently cultivated fields for insects, particularly grasshoppers. They build a simple scrape nest on the ground, in which they lay 3–4 eggs. Other proposed plans of preservation include protecting remaining breeding and wintering habitats, and stopping the conversion of grasslands for agricultural purposes. Mountain Plover Program. 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. 22. On 18 May 1995 I observed two adult Mountain Plovers 5 mi west and 1.25 mi north of Bushnell in southwest Kimball county. "Avian Conservation and Ecology" Vol. Often, they pick prairie dog towns for their nest sites. It often associates with livestock, which attract and stir up insects. Disturbed xeric grasslands with short, sparse vegetation provide breeding habitat for mountain plovers (Charadrius montanus) across the western Great Plains. More than half of egg clutches are lost to predation or accidental trampling. 2012, Pierce et al. Decreased nest survival associated with low temperature in a high-elevation population of Mountain Plover. A total of 278 nests were found 2002-2007, all but six in agricultural fields, … We monitored Mountain Plover nests and chicks from April through July on private lands covering approximately 2100 km. These animals historically maintained the short grass and open-ground habitat favored by this species. Behrens, C., Z. J. Ruff, T. M. Harms, and S. J. Dinsmore. After the female lays her first clutch of eggs, the male starts incubating that nest, while the female goes on to lay another clutch in a second nest. One of these conservation methods is to promote cattle grazing practices that mimic the natural effects of bison. Mountain Plover Nest Survival We monitored the fate of 84 mountain plover nests (41 in 2011, 43 in 2012), of which 38 were located on recent burns and 46 were located on active prairie dog colonies. More than half of egg clutches are lost to predation or accidental trampling. 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. Skrade, P, Dinsmore, S. (2013). The male will create two nests out in the open soil and often decorate with bits of old wheat stubble (harvested debris). The mountain plover (Charadrius montanus) is a bird species with very speciic habitat needs when it breeds in the shortgrass and mixed grass regions of the western Great Plains. In general, the mountain plover needs at least 25–50 acres of suitable habitat for foraging. Mountain Plover Population Responses to Black-Tailed Prairie Dogs in Montana. A gregarious species, Mountain Plovers can often be found in loose flocks of up to several hundred birds, especially in winter. deer nest. Mountain plovers nest on bare ground in early spring (April in northern Colorado). We used logistic regression to test for the effect of distance to edge on mountain plover nest success. During mating the male will set a territory and perform displays to attract a female. Mountain Plover habitat selection and nest survival in relation to weather variability and spatial attributes of black-tailed prairie dog disturbance Courtney J. Duchardt,1,*, Jeffrey L. Beck,1 , and David J. Augustine2 1 Department of Ecosystem Science and Management and Program in Ecology, University of Wyoming, Laramie, Wyoming, USA The Wilson Bulletin, 117(1):15-22. Survival in Mountain Plovers. This is where their camouflaged feathers come in handy. Biologist Larry Snyder writes about the find and RMBO’s plover nest conservation program on the RMBO blog. Plovers like to nest among prairie dog colonies because the foraging and burrowing that these animals do expose even more bare soil which creates an ideal habitat for plover nest sites. Their preferred land areas contain clay loam soils, as the sandier soils are less reliable when sand can easily be blown around, covering nests, obscuring vision, and irritating eyes. These animals are grazers that keep vegetation short. It often associates with livestock, which attract and stir up insects. Nest survival of Mountain Plover, a precocial species, has been estimated across the species’ breeding range, including areas in Colorado (e.g., Graul 1975, It feeds mostly on insects and other small arthropods. A nest made in a colder climate with less precipitation has a better chance of survival. After the cold start to spring, this newly laid nest with a clutch of three eggs was an important find. <, Victoria J. Dreitz, Reesa Yale Conrey, Susan K. Skagen, (2012): Drought and Cooler Temperatures Are Associated with Higher Nest, Stephen J. Dinsmore, Michael B. Wunder, Victoria J. Dreitz, and Fritz L. Knopf, (2010): An Assessment of Factors Affecting Population Growth of the Mountain Plover. 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. The breeding season usually extends over the summer months and ends sometime around late July or early August. Journal of Field Ornithology, 80(1):27-34. 2002, Mettenbrink et al. The Wilson bulletin (Wilson Ornithological Society). The birds were in an area of short-grass prairie interspersed with clumps of prickly pear and bare ground. MOUNTAIN PLOVER BREEDING ECOLOGY: HOME-RANGE SIZE, HABITAT USE, AND NEST SURVIVAL IN AN AGRICULTURAL LANDSCAPE by COLIN ALLAN WOOLLEY B.A., Prescott College, 2006 A thesis submitted to the Faculty of the Graduate School of the University of Colorado in partial fulfillment of the requirements for the degree of Master of Science Biology Program 2016 This ground-nesting species exhibits an uncommon split-clutch mating system, in which each member of a pair simultaneously incubates a nest and uniparental care continues throughout brood-rearing. The male Plover can be aggressive when defending his territory against other male piping plovers. This page was last edited on 13 November 2020, at 14:52. Mountain plovers share habitat with prairie dogs at many core breeding sites, and with kangaroo rats on winter habitat in California. Egg-Size Investment in a Bird with Uniparental Incubation by Both Sexes. 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. This native Nebraska shorebird prefers flat, dry, open areas, which can include agricultural landscapes and shortgrass prairies. Lockwood and Freeman (2004) describe Mountain Plover as a very rare summer resident in the Panhandle and Trans-Pecos regions of this state. Nest site selection of the mountain plover (Charadrius montanus) was studied on the Charles M. Russell National Wildlife Refuge, Montana, during 1982. Adults will lead chicks away from the nest scrape to seek shaded, sheltered spots under tall vegetation or even in the shadow of a nearby water tank. Females can mate with several males and have several male-tended nests in one breeding season. In certain parts of their range Mountain Plovers rely almost exclusively on black-tailed prairie dog (Cynomys ludovicianus) colonies as nesting habitat. It takes five or six days to complete set of three eggs. Nest: Site is on flat open ground. Habitat loss and altered disturbance regimes have led to declines in many species of grassland and sagebrush birds, including the imperiled Mountain Plover (Charadrius montanus). Other insect prey includes crickets, beetles, and flies. Both sexes are of the same size. Mountain plovers like to build their habitats in prairie dog colonies, meaning that an increase in prairie dogs will coincide with an increase in mountain plovers. Journal of Field Ornithology, 83 (2): 154–165. Nest is shallow scrape in soil. The grassland plover species is known to nest in places that have recently been disturbed by factors such as burning or … Mountain Plovers are known to nest in a protracted manner; nesting in Montana may extend from late May to late July (Johnsgard 1986, Knowles and Knowles 1993). Nest predators are the biggest cause of nest destruction. Density and Abundance of Mountain Plovers in Northeastern Montana. One factor common to all breeding areas is that the land must include extensive bare ground. Mountain plovers nest on bare ground in early spring (April in northern Colorado). Mountain plovers nest in four habitat types: 1) native short- and mixed-grass prairie, 2) semi-desert sites, 3) prairie dog colonies, and 4) agricultural land. Dinsmore S, White G, Knopf F. 2005. But with a great number of prairie dogs eliminated throughout their range, mountain plover habitat has also been severely restricted. The Bird Conservancy and Colorado Parks and Wildlife operated a nest-marking program for Mountain Plovers breeding in Colorado from 2003-2008. the Mountain Plover and agricultural practices in 2003 plan to investigate Mountain Plover use of black-tailed prairie dog colonies as well (F. Knopf, pers. 2002). Local population managers can best help the plovers by protecting the land and prairie dog colonies from human disturbances such as mining, and monitoring the size and health of suitable plover habitat in each region. Additional study is needed to help ensure the continued presence of mountain plovers in Oklahoma. Mountain plovers are selective in choosing nest sites, preferring expansive arid flats with very short grass and a high proportion of bare ground, and often selectively nest in prairie dog towns. In Medieval England some migratory birds became known as plovers because they returned to their breeding grounds each spring with rain. Females leave their first clutch to be incubated and tended to by the male and then lay a second clutch, which she tends to herself. Fritz Knopf has closely studied the mountain plover, and has tracked population declines. This is particularly the case after the chicks have hatched. In the northern Great Plains, piping plover nest on riverine sandbars and on wide, flat, open, sandy, and sparsely-vegetated beaches along inland lakes and reservoirs. They lay three eggs per clutch; the eggs are off-white with blackish spots. "Avian Conservation and Ecology" Vol. Nest lining (including pebbles, grass, chips of manure) added mostly during incubation. STATUS. May, Holly. Prairie dogs towns contain patches of bare ground, very short grass, and attract many insects. In appearance it is typical of Charadrius plovers, except that unlike most, it has no band across the breast. Knopf, Fritz L. & Wunder, M.B (2006): Mountain Plover. A significant percentage of the Mountain Plover's global population winters in the Chihuahuan Grasslands of Mexico. Mountain plovers often are associated with prairie-dog colonies or other forms of surface … Mountain Plovers nest only in areas with sparse vegetation or bare ground, such as prairie dog towns. The female Plover ultimately chooses the nest site, selecting one of the scrapes that was created by the male. Madison: Wildlife Habitat Management Institute, 2001. Fritz L. Knopf and M. B. Wunder Version: 1.0 — Published March 4, 2020 Text last updated December 1, 2006 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. The Mountain Plover nest marking program was developed in 2003 by Fritz Knopf in cooperation with RMBO and the Colorado Division of Wildlife, to locate and protect Mountain Plover nests from accidental tillage on privately-owned agricultural fields. Plovers eat small invertebrates, and their foraging style is what sets them apart from other shorebirds. Predator density influences nest attendance of … 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. Most species do not build nests, but simply make a small indent in the sand and lay their eggs in that. The first bird was along the road south of the fenceline, just after the road climbs on top of the plateau. The connection between mountain plovers and prairie dogs is particularly strong in Montana, but less so in the grasslands of Colorado and the grasslands and shrub-steppe habitats of Wyoming. Most birds winter in California in an area of high rates of human population growth. I observed both birds almost continuously from 1-2 p.m. MDT. On featureless plain, nest is often placed close to some conspicuous object, such as a pile of cow manure. An unknown but possibly large fraction of females leave their first clutch to be incubated by the male and lay a second clutch, which they incubate. Mountain Plovers nest on bare ground in early spring (April in northern Colorado). Mountain plover habitat. Across all samples, the daily probability of nest survival was 0.975 (0.004 SE, 0.965窶・.982 95% CI). 1-11. Goguen, C. (2012). The mountain plover builds its nest on open prairie. We developed a candidate set of 5 a priori models. This knowledge can be useful in mountain plover conservation efforts. In many areas nesting mountain plovers are strongly associated with prairie dog colonies, where in fact there is a good percentage of ba… I observed both birds almost continuously from 1-2 p.m. MDT. <. The plover comes back each spring to its breeding grounds, and so the wrong name mountain plover was given to the species. Mountain plovers only nest in areas with sparse vegetation or bare ground, such as prairie dog towns. Both parents incubate and care for the young, although newly hatched chicks walk and feed themselves soon after hatching. Nest-Site Selection. The Wilson Journal of Ornithology, in press. Around late July, mountain plovers leave their breeding range for a period of post-breeding wandering around the southern Great Plains. Micro-Habitat Characteristics of Mountain Plover Nest Sites In the construction of suitable plover habitats, more success would be found in short-grass prairie habitats. Mountain Plovers nest only in areas with sparse vegetation or bare ground, such as prairie dog towns. The eggs in … Population growth can be helped more by learning more about post-egg survival. Reporter - Herald. In Oklahoma, 90% of mapped mountain plover locations are in cultivated fields, often bare and flat. Mountain Plovers nest in shortgrass prairie, especially where blue grama, buffalo grass, and western wheat grass are dominant; and in grassy semidesert with scattered saltbush, sage, prickly pear, and yucca, at elevations ranging from 2,100 to 10,663 feet. probability that a nest will be successful with ≥ 1 egg hatching (precocial species) or ≥ 1 nestling fledging (altricial species; Dinsmore et al. Adults will dive on intruders, use loud noises and swooping or act as though they have a broken wing in an attempt to lure the intruder away from the nest. We suspect that a Mountain Plover initiated the nest and was first to lay eggs; and the Killdeer later parasitized the nest and re-mained to incubate, possibly after loss of its own nest. 2019. In 1832 American naturalist John Kirk Townsend spotted a species of unknown bird near the Rocky Mountains, and assumed that all these birds live in mountains. Egg size decreases as the breeding season goes on because of the high energy cost on the females. It is also believed it is easier for them to spot insects to eat. Our estimate of nest survival is low compared to previously reported nest survival and hatch rates from other Mountain Plover breeding sites, which range from 0.27 to 0.70 and is much lower than a previously reported hatch rate of 0.60 in South Park (Graul 1975, Dinsmore et al. Plovers also typically do not nest as far to the north as most sandpipers and do not migrate as far. Most mountain plovers nest in Colorado, Montana, and Wyoming. A Purple Sandpiper in the Rocky Mountains. Plover aggression - swooping and screeching. Increase in soil moisture may the environment of bare grounds and short grass that prairie birds thrive in. 1 Article. Because of this, it is a primary driving force of survival rate. Limiting Factors Table 1 provides a summary of mountain plover habitat requirements. 2000, Vol 112, Num 4, pp 454-456 ; ref : 17 ref. It's also nicknamed “Prairie Ghost” for its habit of freezing in place when threatened, blending perfectly into its grassy surroundings. Other species line their nests with stones or pebbles. 24 04 2013: Print. The mountain plover needs about 70 acres of territory for breeding, and about 25 acres for survival in non-breeding times. Unlike most plovers, it is usually not found near bodies of water or even on wet soil; it prefers dry habitat with short grass and bare ground. The mountain plover builds its nest on open prairie. Prairie dogs towns contain patches of bare ground, very short grass, and attract many insects. RMBO’s field crew discovered its first Mountain Plover nest of the season on May 8. On 18 May 1995 I observed two adult Mountain Plovers 5 mi west and 1.25 mi north of Bushnell in southwest Kimball county. Spring migration is apparently direct and non-stop. The nesting territory must have a bare round with short, sparse vegetation. The chicks can walk and follow their parents as soon as they hatch, but the parents must protect them from predators and lead them to food. A mountain plover nest has a survival rate that ranges from 26 to 65%. Temperature has been previously linked with Mountain Plover nest survival (Dreitz et al. The Condor, 115 (3): 508–514. 5 No. It breeds in the high plains of North America from extreme southeastern Alberta and southwestern Saskatchewan to northern New Mexico and the Texas panhandle, as well as an isolated site in the Davis Mountains of West Texas. Most of our current knowledge of Mountain Plover in Nebraska has come from extensive field work carried out 2002-2016 in the southwest Panhandle by Bird Conservancy of the Rockies (Bly et al 2008). Plovers are very protective of their nests and chicks. Mountain Plover.
