Greater Prairie Chicken Ranges, Movements, and Habitat Usage in Kansas

Duration of Fertility in Capercaillie Hens after Separation from Males

“…comm. ), and Robel et al (1970) described a Greater Prairie Chicken Tympanuchus cupido pinnatus hen that lost three completed clutches within the same season and remated at a different booming ground before each nesting. This indicates that females, in some instances at least, select new mates to fertilize repeat clutches.…”

Prairie chickens on the Sheyenne National Grasslands: September 18, 1987; Crookston, Minnesota

“…Use index (Robel et al 1970b) by display grounds of various grazing management treatments (table 9) indicates that display grounds have preferably moved into pastures of 2, 3 and 4 pasture systems that had been grazed 2, 3 or 4 periods the previous year. Pastures of 3 and 4 pasture systems that had been grazed for only one period in mid season or deferred until September were not preferably used by prairie grouse for courtship display.…”

Environmental Impacts of Wind Power Development on the Population Biology of Greater Prairie-Chickens

“…Lek count data from monitoring programs of the Kansas Department of Wildlife, Parks, and Tourism indicate that prairie chicken numbers have declined in Kansas during the past 30 years (Rodgers 2008). Prairie chickens are thought to be sensitive to disturbance because they have large home ranges, and females may move up to 30 km from lek sites to nest (Robel et al 1970, Schroeder 1991, Augustine and Sandercock 2011. Previous studies have provided evidence that female prairie chickens may avoid disturbance from oil and gas development and power lines (Pitman et al 2005, Pruett et al 2009, Hagen et al 2011).…”

“…Two perpendicular, 9 m sampling transects were centered on the nest bowl in a north-south and east-west orientation. Using a Robel pole, four visual obstruction readings (VOR) of the vegetative cover screening 1 dm segments of the pole were estimated at the nest from a distance of 2 m and a height of 0.5 m along each of the four transect arms (Robel et al 1970). Non-overlapping vegetation cover (% grass, forbs, shrub, detritus and bare ground) was estimated at three equally spaced sub-sampling locations along each transect arm using a 20 x 50-cm Daubenmire sampling frame.…”

“…Core use and home range area buffers were centered around each nest at a radius of 200 and 1000 meters; respectively. Buffer circumferences were determined based on the approximate core use area (13 ha) and home range size (310 ha) of a breeding prairie chicken (Osborne et al 2001, Poirazidis et al 2004, Robel 1970. The portion of the entire study site available to nesting prairie chickens was designated by a 5 km buffer around the minimum convex polygon of all nest locations.…”
