The British Columbia Coastal Waterbird Survey by Anonim Pdf

"The coastal habitats of British Columbia support some of the highest densities of seabirds, waterfowl and shorebirds in the eastern North Pacific. Globally significant wintering and migratory populations of waterfowl and shorebirds use the region's productive estuarine, tidal flat, rocky and sandy shoreline and inshore aquatic habitats. Birds and their habitats in British Columbia are subject to a wide range of anthropogenic influences including recreation, industrial and residential development, and increasing shipping traffic. Several internationally recognized Important Bird Areas are immediately adjacent to major population centers, and are thus vulnerable to disturbance, habitat loss and alteration, toxic effluent discharge and chronic oil pollution"--Abstract.

The British Columbia Coastal Waterbird Survey by Shannon Scott Badzinski,Canadian Wildlife Service. Pacific and Yukon Region,Bird Studies Canada Pdf

The British Columbia Coastal Waterbird Survey (BCCWS) is a volunteer-based survey administered by Bird Studies Canada (BSC), with support from the Canadian Wildlife Service (CWS), that focuses on monitoring the bird populations in and around the Strait of Georgia. CWS and BSC agreed to undertake a formal evaluation of the ability of the BCCWS to fulfil its major monitoring objectives after five years of data collection. The primary objectives of the surveys are: to assess the size of non-breeding waterbird populations in coastal areas of British Columbia; to assess trends in numbers and distribution of coastal waterbirds; to assess and monitor the importance of individual sites for waterbirds; and to improve understanding of the ecology of waterbirds, including responses to natural and anthropogenic change. This report provides an overview of the BCCWS protocol, database structure and management, and a more detailed appraisal of the analyses conducted to assess the survey's ability to meet its goals. The report's primary objectives are to: provide a quantitative assessment of the ability of the BCCWS to detect changes in the abundance of waterbirds (and other species of interest) in the Georgia Basin; derive annual species abundance indices and assess linear trends in abundance of the first five years of the survey; and present data summaries of species abundances and distribution at BCCWS sites. It discusses trends in species abundances and distributions, compares BCCWS results with other published and unpublished survey data, and proposes recommendations to improve the quality and utility of data collected by the BCCWS.--Document.

A Critical Review of the Aerial and Ground Surveys of Breeding Waterfowl in North America by Graham W. Smith Pdf

The U.S. Fish and Wildlife Service and the Canadian Wildlife Service in cooperation with others have conducted an annual survey of breeding waterfowl throughout central Canada, the north-central United States, and Alaska since 1955. The area comprises more than 50 strata of habitats. Ducks are counted from aerial transects, and the counts are adjusted upward to account for birds that are not observed by aerial crews. These adjustments, called visibility correction factors, are developed from counts on the ground during which all waterfowl are assumed to have been detected. Counts on the ground are made of a subsample of the aerial survey. Visibility correction factors are calculated for each species and for each aerial crew. The total number of ducks by species and by strata is then calculated as the product of the observed density, the visibility correction factor, and the area of the strata.
