The breeding season usually begins in the United States starting in late March throughout April. The Attwater's Prairie-Chicken is a member of the North American grouse family. The belly and under tail coverts are white. Prairie Chicken – This region is almost entirely occupied by lesser prairie chickens and areas included in their range are closed to prairie chicken hunting (see map above for unit boundaries). Sharp-tailed grouse (Sharptails) and greater prairie-chickens, collectively referred to as prairie grouse, are closely related native birds that are primarily distributed across prairie-dominated landscapes of central and western South Dakota. [2], The greater scaup was formally described by Carl Linnaeus in 1761 under the binomial name Anas marila. Some of the primary factors contributing to this decline are habitat loss, contaminants, changes in breeding habitat, and a lower female survival rate. Recent taxonomic changes affecting the British and Western Palaearctic lists", https://en.wikipedia.org/w/index.php?title=Greater_scaup&oldid=1004686468, Creative Commons Attribution-ShareAlike License, This page was last edited on 3 February 2021, at 21:33. Maps are derived from records of lekking sites for greater prairie chickens. Species Range. [17] Distinguishing greater from lesser scaups can be difficult in the field. These booming grounds are the area in which they perform their displays in hopes of attracting females. Conservation measures are underway to ensure the sustainability of existing small populations. GPChickenOverallRange is an ESRI SDE Feature Class showing Colorado greater prairie chicken distribution. Prairie Chicken Range in Kansas Due to increasing pressures on prairie chicken habitat, there is a need to better define the current range and distribution of greater and lesser prairie chickens in Kansas. Sharp-tailed Grouse and Greater Prairie-chicken. The greater prairie chicken or pinnated grouse (Tympanuchus cupido), sometimes called a boomer,[2] is a large bird in the grouse family. common predators of greater prairie-chicken nests are snakes, coyotes, skunks, raccoons, red foxes, badgers, crows, and ground squirrels. Range. One of the most famous aspects of these creatures is the mating ritual called booming. Ring-necked Pheasants stride across open fields and weedy roadsides in the U.S. and southern Canada. This paper presents data on greater prairie chicken home range and mobility gathered between 1964 and 1968. [11][12] Based on size differences, a Pleistocene paleosubspecies, Aythya marila asphaltica, has also been described by Serebrovskij in 1941 from fossils recovered at Binagady, Azerbaijan. Kansas is home to both the greater and lesser prairie chickens. [2] During aerial population surveys greater and lesser scaup are counted together, because they look almost identical from the air. Tympanuchus cupido cupido† occupy over 100,000 acres in total, in 49 designated locations. One, 16 km survey was conducted in each of 36 counties distributed across the Greater Prairie-Chicken range within Kansas. Their main threat is human development, although they are preyed upon by owls, skunks, raccoons, foxes, coyotes, and humans. Once found throughout the tallgrass region, Greater Prairie-Chicken populations have been reduced by habitat fragmentation in eastern Nebraska. [4][5] The species is now placed in the genus Aythya that was introduced for the greater scaup by the German zoologist Friedrich Boie in 1822.[6][7]. Common predators of the greater scaup are owls, skunks, raccoons, foxes, coyotes, and humans. [27] A larger clutch could indicate brood parasitism by other greater scaups or even ducks of other species. North Dakota Game and Fish Department 100 N. Bismarck Expressway, Bismarck, ND 58501-5095 Phone: 701-328-6300, Contact Us. Description. Hens lay between 5 and 17 eggs per clutch and the eggs take between 23 and 24 days to hatch. They have dull blue bills and white on the face. Once ranging throughout the Southwest, today the only breeding population of ocelots in the U.S. is in Texas, where fewer than 60 ocelots remain in two small populations near the Mexican border. [10] The subspecific classification of East Asian birds is uncertain as different authors have designated them as either race, or a third subspecies A. m. mariloides, though the latter name has been deemed invalid due to being used as a synonym for the Lesser Scaup A. Males sport iridescent copper-and-gold plumage, a red face, and a crisp white collar; their rooster-like crowing can be heard from up to a mile away. Habitat requirements Greater prairie-chickens are primarily dependent upon grasslands, ... parts of the northern greater prairie-chicken’s range, and Chinese tallow and Macartney rose have become a nuisance in Attwater’s prairie-chicken habitat. Feb 4, 2011 (Last modified Oct 5, 2011) ... GPChickenHistoricRange is an ESRI SDE Feature Class showing Colorado greater prairie chicken distribution. During this time the males establish booming sites where they display for the females. A phylogenetic analysis of the diving ducks, examining the skeletal anatomy and skin, found that the greater and lesser scaups are each other's closest relatives, with the tufted duck as the next closest relative of the pair.[14]. Pheasants lay their eggs in prairie-chicken nests. Greater scaup are hunted from shorelines and in open water hunting blinds or layout boats, low-profile kayak-like boats that hunters lie inside. The type locality is Lapland. The optimal molting lake is fairly shallow and has an abundance of food sources and cover. Considerable effort is still needed to ensure a self-sustaining population, and the hunting community can play a valuable role. After population bottleneck, human management of populations can also produce a loss of genetic variation and genetic diversity in the species.[11]. However excessive selenium can cause reproductive harm and is highly toxic. Adults of both sexes are medium to large chicken-like birds, stocky with round-wings. Current Range . The adult female has a brown body and head, with white wing markings similar to those of the male but slightly duller. The greater scaup's name may come from "scalp", a Scottish and Northern English word for a shellfish bed,[13] or from the duck's mating call: "scaup scaup". Relative abundance is depicted for each season along a color gradient from a light color indicating lower relative abundance to a dark color indicating a higher relative abundance. Michigan Dept. The map is provided as a general reference of where occurrences of this species meet NHI data standards and is not meant as a comprehensive map of all observations. [19], In Europe, the greater scaup breeds in Iceland, the northern coasts of the Scandinavian peninsula, including much of the northern parts of the Baltic Sea, the higher mountains of Scandinavia and the areas close to the Arctic Sea in Russia. A prairie chicken taken on the wing is nothing short of an upland trophy. Distribution map of the greater prairie-chicken. Oil and sewage pollution also threaten this duck. Prairie Chicken – This region is almost entirely occupied by lesser prairie chickens and areas included in their range are closed to prairie chicken hunting (see map above for unit boundaries). Back to Top. In my experience, prairie chickens prefer to use a slope to their advantage. Formerly widespread throughout the grasslands of the Great Plains and Upper Midwest, the Greater Prairie-Chicken is now largely restricted to the northern Great Plains states of North Dakota, South Dakota, Nebraska, Kansas, and northwestern Minnesota (Figure 1). [18], Although the greater scaup faces numerous threats, the most significant challenge to their survival is habitat degradation caused by a mix of human development and runoff. affinis. The young are raised by the female and fledge in one to four weeks, are completely independent by the tenth to twelfth week, and reach sexual maturity by age one (Ammann, 1957). It has a blue bill and yellow eyes and is 20% heavier and 10% longer than the closely related lesser scaup. A drought can destroy food and make it difficult for the chicks. Adult males have orange comb-like feathers over their eyes and dark, elongated head feathers that can be raised or lain along neck. A. m. nearctica (Stejneger, 1885) (Nearctic greater scaup). Slightly smaller and darker than it's close relative the Greater Prairie-Chicken, this southern subspecies of the now extinct Heath Hen once roamed an extensive range on the coast of Texas and Louisiana. Continuous tracts of grassland and sandsage prairie are best, but the size requirement can be met with much smaller blocks. 1997). Map Format. The Greater Prairie-chicken (T. c. pinnatus) is extinct or in danger of extinction in 15 states, but numerous enough to be legally hunted in four states (Schroeder and Robb 1993), with the largest remaining populations in Kansas, Nebraska and South Dakota (del Hoyo et al. Greater Prairie Chicken Range Map. Understanding Greater Prairie-Chicken response to ... grid within the 100% minimum convex polygon across all home ranges on the landscape to make a predictive map. In reality the eggs did not hatch and the young usually die because the mother is not there to incubate the eggs. Greater White-fronted Goose: This medium-sized goose has a dark-brown body and the underparts are barred and flecked with black. The greater prairie chicken or pinnated grouse (Tympanuchus cupido), sometimes called a boomer, is a large bird in the grouse family.This North American species was once abundant, but has become extremely rare and extirpated over much of its range due to habitat loss. On their migration across the Great Lakes, greater scaups are at risk of ingesting selenium by eating the invasive zebra mussels, which can render a hen infertile. There is a smaller population of greater prairie-chickens in southeastern Nebraska. In America and Canada, waterfowl must be hunted with non-toxic shot. Greater!Prairie)chicken! Greater scaup nest near water, typically on islands in northern lakes or on floating mats of vegetation. Maps » Greater Prairie Chicken Unit Map Notice. There are two species of prairie chickens, the greater prairie chicken, and the lesser prairie chicken. (Kansas Department of Wildlife and Parks) It was also found that the prairie-chickens avoided communication towers and rural farms. The front of the face has a white patch and the bill is usually pink-orange. When the snow is thick they "dive" into the snow to keep warm. [19] Greater scaup are hunted with shotguns because they must be shot on the fly, a challenging task, as they can fly at up to 121 km/h (75 mph). Greater-Prairie Chicken. [16] Owing to the greater scaup's webbed feet and weight, it can dive up to 6 metres (20 ft) and stay submerged for up to a minute, allowing it to reach food sources that are unobtainable to other diving ducks. Its neck, breast, and tail feathers are a glossy black, while its lower flanks are vermiculated gray. Greater scaup can catch avian influenza, so future outbreaks have the potential to threaten greater scaup populations. The greater prairie chicken or pinnated grouse (Tympanuchus cupido), sometimes called a boomer, is a large bird in the grouse family.This North American species was once abundant, but has become extremely rare and extirpated over much of its range due to habitat loss. Report All Poachers: 701-328-9921. As the prairies to the south and west were lost to agriculture and development, and the southern half of Wisconsin was logged, the prairies spread northward into the abandoned farmland. It is also found in Asia and is present in the Aleutian Islands year round. Its natural habitat includes undisturbed prairies, especially those of tall grass. The legs are orange. It was found in a radio telemetry study conducted by Kansas State University that "most prairie chicken hens avoided nesting or rearing their broods within a quarter-mile of power lines and within a third-mile of improved roads." … Ring-necked Pheasants stride across open fields and weedy roadsides in the U.S. and southern Canada. The greater scaup dive to obtain food, which they eat on the surface. Greater Prairie-Chicken: Nearly extinct, this species was almost gone by the end of 1930s. It spends the summer months in Alaska, Siberia, and the northern parts of Europe. Greater Prairie-chicken (GPC) Scientific name: Tympanuchus cupido Conservation status: Is a game bird in Kansas, Colorado, Minnesota, South Dakota, and Nebraska. Females lay a clutch of six to nine olive-buff-colored eggs. From six million acres ranging from the Nueces River in Texas to Bayou Teche in Louisiana, this bird has seen its range crushed to two small pockets of habitat in Galveston and Colorado counties. As with many other bird species, the adult females have shorter head feathers and also lack the male's yellow comb and orange neck patch. Summary. The 2010 American scaup population survey was 4.2 million scaup,[34] however, the worldwide greater scaup population survey estimated 1,200,000 to 1,400,000 mature greater scaup. Click here to return to the species description page . Greater Prairie Chicken Historic Range. Since the 1980s, scaup populations have been steadily decreasing. Scattered populations are found father south and east of the core breeding range. The greater prairie chicken or pinnated grouse (Tympanuchus cupido), sometimes called a boomer, is a large bird in the grouse family.This North American species was once abundant, but has become extremely rare and extirpated over much of its range due to habitat loss. When flocks are on flowing water, they will face the current, and as the ducks float backwards, some fly to the front of the flock to maintain position. [3] This sterilization of hens is causing the population to decrease. Metal leg bands are placed on them, so that if the scaup is killed by a hunter or if it is captured by another banding group, the number on the band can be reported to biologists and wildlife organizations. Wisconsin's greater prairie chicken (Tympanuchus cupido pinnatus) began its return from near extinction in this state when, in 1954, the Wisconsin Department of Natural Resources (WDNR) entered into a partnership with Wisconsin conservation groups to establish a prairie chicken management program on the Buena Vista Grasslands in southwestern Portage County. [6] Throughout North America, it is thought that their current population has declined severely, to approximately 500,000 individuals. These sometimes drenching rains can wreak havoc on their chicks. The upper wing has a white stripe starting as the speculum and extending along the flight feathers to the wingtip. [33] There was no difference in concentration when comparing genders. Fact!Sheet!!

GPChickenHistoricRange is an ESRI SDE Feature Class showing Colorado greater prairie chicken distribution. The brown females blend in with their field habitat. [8] Greater scaup from North America and East Asia are considered a separate subspecies A. m. nearctica, and are distinguishable from those in Europe and Asia by a higher forehead "bump", and the male having stronger vermiculations, worm-like carvings or marks[9] on the mantle and scapulars. Adults are about 16.9 in (43 cm) long, and weigh between 24.7–42.3 oz (700–1200 g). The Mexican gray wolf has rebounded from near extinction in the 1970s to an estimated 131 in the wild at the end of 2018. Greater prairie chickens do not migrate. [29] In freshwater ecosystems, the greater scaup will eat seeds, leaves, stems and roots, along with sedges, pondweeds, muskgrass, and wild celery. The belly and under tail coverts are white. They differ from Sharp-tailed Grouse in being barred below (rather than scaled/spotted) and in having a dark, rounded tail (instead of a mostly white, pointed one). Selenium is an occurring semimetallic trace element that occurs naturally in some soils and minute amounts are necessary for animal life. Greater prairie chickens prefer undisturbed prairie and were originally found in tallgrass prairies. Greater prairie-chickens have a core range in the eastern Sandhills of Nebraska, but are also found where suitable habitat exists in portions of northeastern Nebraska as well as South-Central and Southwest Nebraska.

The conversion of native prairie to cropland is very detrimental to these birds. Maps are derived from records of lekking sites for greater prairie chickens. [15] After the female lays the eggs, the drake abandons the female[24] and goes with other drakes to a large, isolated lake to molt. The Kansas Department of Wildlife and Parks and the Kansas Biological Survey are … Drake greater scaup have a soft, quick whistle they use to attract the attention of hens during courtship, which takes place from late winter to early spring, on the way back to their northern breeding grounds. The Minnesota Prairie Chicken Society was founded in 1973 out of concern for the plight of the prairie chicken. [8] Nonetheless, sightings and encounters continue to occur in the south-central regions of Alberta and Saskatchewan, along with southern Ontario, where sightings are extremely rare.[9]. [32] Greater scaup, when moulting and during the winter, are threatened by escalated levels of organochloride contaminants. The genus name Aythya is derived from the Ancient Greek aithuia which refers to a seabird mentioned by Aristotle and others and is thought to refer to a duck, auklet or other seabird. 2021 Tentative Season Dates The North Dakota Game and Fish Department annually provides its best estimate for opening dates to help hunters prepare for hunting seasons. Greater prairie chickens are not threatened by severe winter weather. Consew. In the fall, greater scaup populations start their migration south for the winter. Map Category. You can generally avoid flat or seemingly level prairie. The head of the greater tends to be more rounded, and the white wing stripe is more extensive. [31] Greater scaup often find themselves entangled in fishing nets, thus large numbers of them drown in nets each year. [citation needed] In May 2000, the Canadian Species at Risk Act listed the greater prairie chicken as extirpated in its Canadian range (Alberta, Saskatchewan, Manitoba, Ontario). The drake's belly and flanks are a bright white. The male prairie-chickens stay on this ground displaying for almost two months. Choose a location below to bring up more detailed information and downloadable maps. They were a popular game bird, and like many prairie birds, which have also suffered massive habitat loss, they are now on the verge of extinction, with the wild bird population at around 200 in Illinois in 2019.
