One population in northwest Minnesota had the most locations in Clearwater, Kittson, Marshall, Pennington, Polk, Red Lake, and Roseau Counties. 2006). Klott, J. H., and F. G. Lindzey. Prose (1987) stated that females require appropriate grassy, brush, or woody vegetation within 3.2 km of the lek site. 1998, Hutto and Young 1999, Maxell 2000, Foresman 2012, Adams 2003, and Werner et al. Similar retractions of the species’ range were described by Berg (1990) in Wisconsin and in Michigan. 2016. Great Basin Naturalist 49:275–277. 2016) provided a moderate conservation score of 10/20 for the Sharp-tailed Grouse. 2015. (2000) quantified the landscapes surrounding occupied and unoccupied lek sites in the species’ east-central range of Minnesota. Unfortunately, its geographic distribution has contracted by an estimated 90 percent. Avian Conservation Assessment Database [Online]. The species was found in 6.9% (337/4,857) of the surveyed blocks and in 5.4% (127/2,337) of the priority blocks (Figure 3; Table 1). Berg (1997) summarized that an optimum mix for nesting and brood habitat included 35% grass-legumes, 15% cropland, 7% sedge marsh, 25% lowland brush, and 13% young aspen and white birch. Ithaca: Cornell Lab of Ornithology. In 1975, Green and Janssen emphasized the Sharp-tailed Grouse’s distribution as primarily in the northern regions and most numerous in the northwestern part of the state in Beltrami, Lake of the Woods, Marshall, and Roseau Counties. Redmond. Berg (1997) had previously identified the regions including Lac qui Parle, Pope, and Swift Counties as not occupied during pre-settlement times. Western North American Naturalist 76:135–141. Second edition. Mammals of Montana. Breeding distribution and relative abundance of the Sharp-tailed Grouse in North America based on the federal Breeding Bird Survey, 2011–2015 (Sauer et al. Sharp-tailed Grouse, Rick Baetsen. U.S. Department of Agriculture, Forest Service, Rocky Mountain Region. The species’ distribution has also been greatly reduced in the southern regions of its range as well as in British Columbia, Colorado, and Utah. Minnesota Ornithologists’ Union Occasional Papers, no 2. Svedarsky, W. Daniel. In the 1930s, Roberts emphasized that the “Prairie Sharp-tailed Grouse” (as it was formerly known) was “now confined largely to the northern part of the state from Pine County northward and westward in cut-over lands, in natural openings, and in brush areas, to the settled prairies of the west-central counties and the Red River Valley.” This is largely the same area still occupied by the Sharp-tailed Grouse today, though the population has declined even more within this range. Minnesota Birds: Where, When and How Many. Additionally, we are collected DNA samples from captured grouse and other sharp-tailed grouse populations (known Columbian sharp-tailed grouse in Idaho and known plains sharp-tailed grouse in eastern Wyoming) to identify what subspecies sharp-tailed grouse in south-central Wyoming belong to. Partners in Flight (Rosenberg et al. Thesis, University of Wyoming, Laramie, USA. Hendricks, C.R. Missoula, MT: Mountain Press Publishing Company. Montana atlas of terrestrial vertebrates. 1998). Publication No. In another experiment, Roy et al. Berg (1997) emphasized that the species occupied less than one-third of its historic range in Minnesota. Montana Cooperative Wildlife Research Unit, University of Montana, Missoula, MT. To identify these needs we are capturing and attaching VHF radio-transmitters to adult birds in the spring to follow their survival and habitat selection throughout the year. He suggested these were “vagrants” from a population in Thunder Bay, Ontario. The wings have conspicuous white spots, and the breast and flanks have V-shaped brown markings on a snow-white background. 2017a. Version 1.3. January 19, 2010. 1989.

The National Audubon Society (2015; Langham et al. 161 p. Werner, J.K., B.A. They emphasized the importance of the landscape context (e.g., 3000 m radius) surrounding lek sites and the negative effects of woody cover, especially trees, in the horizon around these sites. The MNBBA did not sufficiently detect the species on its point counts and therefore did not provide an estimate. Our research is a collaboration with Bowling Green State University, the Wyoming State Office and Rawlins Field Office of the USDI Bureau of Land Management, Wyoming Game and Fish Department, and the USDA Medicine Bow-Routt National Forest. 1 of 7 subspecies (1 extinct) of sharp-tailed grouse in North America (Connelly et al. 1987. 1999. 2004); Evaluating structural characteristics and distribution of each ecological system relative to the species' range and habitat requirements; Examining the observation records for each species in the state-wide point observation database associated with each ecological system; Calculating the percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system to get a measure of "observations versus availability of habitat". As stated under breeding habitat, Sharp-tailed Grouse are  area sensitive and found primarily in large expanses of suitable habitat which often requires coordinated management with private landowners and several government agencies. 2010). 2015. The Sharp-tailed Grouse is primarily distributed in the northern Great Plains. The Minnesota population was estimated as 7,000 individuals., Roy, Charlotte L., Eric Nelson, and Andrew Gregory. Dyke et al. The Birds of Minnesota. Specifically, our study seeks to answer the following questions: Keinath, D. A., M. A. Andersen, and G. P. Beauvis. They identified extirpations of the species from the early 1900s to 1970 from California, Illinois, Iowa, Kansas, Nevada, New Mexico, and Oregon. 1000 E.
