Habitat use by nongame birds in central Appalachian riparian forests
I sampled bird densities and habitat characteristics along a gradient from a second-order stream to 454 m upland at 16 locations. Total bird density, species richness, and densities of 28 bird species were tested to determine whether riparian habitats influenced bird communities. Total bird density …

Effects of Wind Turbines On Nongame Birds in Conservation Reserve Program Grasslands in Southwestern Minnesota
… wind turbines. The effects of wind turbines on nongame bird composition and density in Conservation Reserve Program (CRP) grasslands was evaluated in summer 1995 along Buffalo Ridge in southwestern Minnesota. Bird density in CRP fields with wind turbines was compared with that found in cropland, …

Effects of Grazing Intensity and Temporal Application of Grazing Treatments on Nongame Birds in North Dakota Mixed-Grass Prairie
… including the habitat selection of breeding birds. Grazing, mainly for livestock production, is still an important land use practice and is one that impacts millions of hectares on both public and private land in the United States. In North Dakota alone, various grazing practices affect over …

Nongame Vertebrate Survey of Sand Lake National Wildlife Refuge, Brown County, South Dakota
… is known about the abundance and distribution of nongame species by primary habitat types in the northern Great Plains. This is due, in part, to the paucity of biological surveys on public and private lands. Even fewer surveys have occurred on isolated ecosystems in this region. Narrative reports …

Effects of Grazing on Nongame Breeding brids, Insects, and Vegetation in Conservation Reserve Program Grasslands in North Dakota
… the effects of various land use practices on nongame birds, insect biomass, and vegetation structure in Conservation Reserve Program (CRP) grasslands in North Dakota. Breeding bird surveys were conducted and insect collections and vegetation measurements were taken in 3 of the 4 CRP tracks …

Effects of Land Use on Avifauna in the Lake Thompson Watershed, South Dakota
… Waterfowl were surveyed first, then all breeding birds, then ring-necked pheasant (Phasianus colchicus) broods. In order to determine the effects of surrounding land use on the distribution of these breeding birds, a Geographic Information System (GIS) was developed for the watershed. The …

Habitat Area Requirements of Prairie Wetland Birds in Eastern South Dakota
… of species varied, but most waterfowl and nongame species occur e4i more frequently in wetlands with intermediate cover-to-water ratios whereas five over-water nesting or secretive nongame species were found in wetlands with greater coverage of emergent vegetation. The occurrence of four …

Habitat ecology of the Painted Bunting on the Ozark Plateau
"Increased public interest in nongame birds in recent years (Payne and DeGraaf 1975) calls for the consideration of such species' requirements by resource management agencies. These requirements must first be determined before a particular species can be considered in any management scheme. The …

Avian Occurrence in Woodlands and Grasslands on Public Areas Throughout Eastern South Dakota
The purpose of this study was to inventory nongame bird species on public lands throughout eastern South Dakota in woodland and grassland habitats of different patch sizes and landscape matrices in various physiographic regions. Nongame birds were surveyed in 524 (99 native and 425 planted) …
