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%...

Use and selection of nesting habitat by sage grouse in Oregon

Creator:: Gregg, Michael A.
Abstract:: Sage grouse (Centrocercus urophasianus) populations in Oregon declined during the past 30 years as a result of impaired productivity. The western subspecies (C. u. phaios) was listed as a candidate for threatened and endangered status by the Department of the Interior in 1985 because of declines in Oregon and Washington...

Effects of habitat manipulations on California quail in western Oregon

Creator:: Oates, Russell M.
Abstract:: The effects of disking, food plantings, and wheat plantings on a population of California quail (Lophortyx californicus) were studied from fall 1976 to spring 1978 on the E.E. Wilson Wildlife Area, Oregon. Twelve 16.2-ha study sites were established: 3 study sites for each treatment and 3 control sites. Disked areas,...

The effects of burning in mountain big sagebrush on key sage grouse habitat characteristics in southeastern Oregon

Creator:: McDowell, Michelle K. D.
Abstract:: Sage grouse are a species of concern because their abundance, distribution, and productivity have declined during the past century. Sage grouse productivity has been linked to specific habitat components including particular forbs and native bunchgrasses. Studies on the effects of fire were conducted in Southeastern Oregon in mountain big sagebrush...

Prey selection by peregrine falcons during the nestling stage in Alaska

Creator:: Hunter, Robin E.
Abstract:: Proper management of peregrine falcons (Falco peregrinus) includes management of its prey. Little quantitative data on prey selection by peregrine falcons have been collected. The objective of this study was to determine species and relative abundance of prey brought to eyries by peregrine falcons during the nestling stage and to...

Habitat use by Western Tragopans in northeastern Pakistan

Creator:: Islam, Kamal
Abstract:: Populations of Western Tragopans Tragopan melanocephalus were studied at two areas (Machiara and Salkhala) in the Neelum Valley of northeastern Pakistan. A total of 130 sightings of birds was noted during the breeding seasons in 1982 and 1983, but only 100 were re-located for vegetation analysis. More sightings of birds...

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...

An analysis of guild structure of avian communities, Columbia River, Oregon

Creator:: Noyes, Cecilia Lea Barham
Abstract:: Effects of habitat and season on guild structure of avian communities were examined for islands in the estuary zone of the Columbia River, Oregon. Bird species were classified into guilds according to their major food item, typical foraging substrate, and foraging behavior. Variation in community structure indices (number of guilds,...

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...
