Grazing intensity effects on the breeding avifauna of North Dakota native grasslands Grazing intensity effects on the breeding avifauna of North Dakota native grasslands
A breeding bird census and plant survey was conducted on 180 samples of lightly, moderately, and heavily grazed and hayed native grasslands in North Dakota in 1974. The ten most important cover plants on each of eight major physiographic landforms in three of the four regions (the Agassiz Lake Plain excluded) overlapped so extensively that only 19 species were involved: 13 grasses or...

The role of observer bias in the North American Breeding Bird Survey The role of observer bias in the North American Breeding Bird Survey
Ornithologists sampling breeding bird populations are subject to a number of biases in bird recognition and identification. Using Breeding Bird Survey data, these biases are examined qualitatively and quantitatively, and their effects on counts are evaluated. Differences in hearing ability and degree of expertise are the major observer biases considered. Other, more subtle influences are...

Procedures for the use of aircraft in wildlife biotelemetry studies Procedures for the use of aircraft in wildlife biotelemetry studies
This is a report on the state of the art methodology and on questions that arise while one is preparing to use aircraft in a biotelemetry study. In general the first step in preparing to mount an antenna on an aircraft is to consult with a certified aircraft mechanic. Aircraft certification is discussed to provide background information concerning the role of the Federal Aviation...

Use of 35-mm color aerial photography to acquire mallard sex ratio data Use of 35-mm color aerial photography to acquire mallard sex ratio data
A conventional 35-mm camera equipped with an f2.8 135-mm lens and ASA 64 color film was used to acquire sex ratio data on mallards (Anas platyrhynchos) wintering in the Platte River Valley of south-central Nebraska. Prelight focusing for a distance of 30.5 metres and setting of shutter speed at 1/2000 of a second eliminated focusing and reduced image motion problems and resulted in high...

Birds of the St. Croix River valley: Minnesota and Wisconsin Birds of the St. Croix River valley: Minnesota and Wisconsin
The St. Croix River Valley encompasses nearly 11,550 km2 in east-central Minnesota and northwestern Wisconsin. A wide range of habitats are available for birds including upland oak, lowland deciduous, maple-basswood, lowland and upland coniferous forests, natural basin wetlands, and grasslands. Situated in the north-central region of the United States, the valley is a biological...
