Sampling in rugged terrain Sampling in rugged terrain
Work in rugged terrain poses some unique problems that should be considered before research is initiated. Besides the obvious physical difficulties of crossing uneven terrain, topography can influence the bird species? composition of a forest and the observer's ability to detect birds and estimate distances. Census results can also be affected by the slower rate of travel on rugged...

Shorebirds of the eastern Bering Sea Shorebirds of the eastern Bering Sea
Largely on the basis of work conducted in western Alaska since 1975, we present an overview of the shorebird resources of the region and discuss their relationship to the littoral and supralittoral habitats of the area. Thirty species of shorebirds occur regularly and comprise an important component of the eastern Bering Sea ecosystem. For a third of these species the region supports the...

The North American Breeding Bird Survey The North American Breeding Bird Survey
A brief history of the North American Breeding Bird Survey (BBS) and a discussion of the technique are presented. The approximately 2000 random roadside routes conducted yearly during the breeding season throughout North America produce an enormous bank of data on distribution and abundance of breeding birds with great potential use. Data on about one million total birds of 500 species...
