Greater sage-grouse reproductive ecology : linkages among habitat resources, maternal nutrition, and chick survival

Creator:: Gregg, Michael A.
Abstract:: Greater sage-grouse (Centrocercus urophasianus) populations declined range wide during the past 50 years. Grouse populations were 2-3 times larger than the current population as recently as the early 1970's. In addition to habitat loss and fragmentation, declines were attributed habitat degradation that caused reduced productivity. Because chick survival remains the...

Breeding season habitat use and response to management activities by greater sage-grouse on Sheldon National Wildlife Refuge, Nevada

Creator:: Davis, Dawn M.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) have experienced declines throughout their range over the last 50 years. Long-term declines in sage-grouse abundance in Nevada and Oregon have been attributed to reduced productivity. From 1995-1997, sage-grouse production on Sheldon National Wildlife Refuge (SNWR), Nevada was greater compared to Hart Mountain National Antelope Refuge...

Response of brood-rearing habitat of sage grouse to prescribed burning in Oregon

Creator:: Pyle, William H. (William Hanson), 1957-
Abstract:: Decline of western sage grouse (Centrocercus urophasianus phaios) in Oregon may be related to the reduced availability of foods in upland sagebrush (Artemisia)-grasslands used for brood-rearing. The goal of this study was to determine primary foods of chicks and the short-term response of brood-rearing habitat to prescribed burning at Hart...

Applications of radiotelemetry to studies of California quail in western Oregon

Creator:: Kilbride, Kevin M.
Abstract:: A partially automated radio-tracking system with semi-continuous azimuth data collection and XYLOG5 and MAP computer programs for azimuth data analysis was used for studies of California quail (Callipepla californica) at the E.E. Wilson Wildlife Area, Oregon, in 1988 and 1989. Movements of 58 hens were monitored daily to determine nest...

Selected life history aspects and habitat use by Merriam's wild turkeys in Oregon

Creator:: Lutz, Robert Scott
Abstract:: Habitat use and reproductive success by Merriam's wild turkey (Meleagris gallopavo merriami) were studied in Wasco County, Oregon, during 1981-82. This low density turkey population selectively used forested cover types characterized by a variety of structural features, species, and age classes. They avoided monotypic forested cover types, used non-forested cover...

Habitat use and selection by sage grouse broods in southeastern Oregon

Creator:: Drut, Martin S.
Abstract:: In Oregon, sage grouse (Centrocercus urophasianus) were common in the eastern portion of the state. Since 1940 populations declined because of decreased productivity. The western subspecies (C. u. phaios) was listed as a candidate for threatened and endangered status in 1985 because of declines in Oregon and Washington and extirpation...

Diet and nutrition of female sage grouse during the pre-laying period

Creator:: Barnett, Jenny K.
Abstract:: Nutrition effects productivity of grouse. Females that obtain high nutrient diets in spring produce larger clutches and larger, more viable chicks than hens on less nutritious diets. Grouse select high nutrient foods to help ensure proper nutrition. Reduced productivity accounted for the decline of sage grouse (Centrocercus urophasianus) populations in...

Foraging ecology of California quail and response of key foods to habitat manipulations in western Oregon

Creator:: Blakely, Kevin L.
Abstract:: Seasonal diet and food selection of California quail (Callipepla californica) were studied at E.E. Wilson Wildlife Area, Oregon, during 1985 to 1987. Analysis of diets of 105 quail, along with information from 117 quail taken during 1976 to 1978 revealed 14 key plant foods. Collectively, the key foods composed 87%...

The ecology of Mountain Quail in Oregon

Creator:: Pope, Michael D. (Michael Dickens)
Abstract:: Mountain Quail (Oreortyx pictus) populations have declined in many areas of the western Great Basin during the past century. Yet the life history of this species is little known. From 1997 to 2000, I studied radio-marked Mountain Quail in Hell's Canyon in northeastern Oregon, in the Cascade Mountains of southwestern...
