Scoters and other waterbirds congregate in dramatic numbers to consume Pacific herring (Clupea pallasi) spawn each spring along most of the Pacific Coast. Spawning occurs later at progressively higher latitudes, and may thus provide critical staging areas for scoters acquiring reserves as they migrate north to breed.
This report summarizes information about the status of duck populations and wetland habitats during spring 2012, focusing on areas encompassed by the U.S. Fish & Wildlife (USFWS) and Canadian Wildlife Services’ (CWS) Waterfowl Breeding Population and Habitat Survey. We do not include information from surveys conducted by state or provincial agencies. In the traditional survey area, which includes strata 1–18, 20–50, and 75–77 (Figure 1), the total duck population estimate (excluding scoters [Melanitta spp.], eiders [Somateria spp.
Twelve species of North American sea ducks (Tribe Mergini) winter off the eastern coast of the United States and Canada. Yet, despite their seasonal proximity to urbanized areas in this region, there is limited information on patterns of wintering sea duck habitat use. It is difficult to gather information on sea ducks because of the relative inaccessibility of their offshore locations, their high degree of mobility, and their aggregated distributions.
Large secondary-nesting birds such as ducks rely on appropriate cavities for breeding. The main objective of this study was to assess the availability of large cavities and the potential of a managed boreal coniferous landscape to provide nesting trees within the breeding area of the eastern population of Barrow’s Goldeneye (Bucephala islandica), a cavity-nesting species at risk in Canada.
The Canadian Arctic contains much of Canada’s coastal and marine zones, and these areas support
tremendous numbers of marine birds. At the start of the 21st century, the Canadian marine zone is
the subject of much concern as a result of a variety of anthropogenic threats. The Canadian
Wildlife Service (CWS) is the federal agency responsible for the conservation of migratory bird
populations and their habitats in Canada. As part of its mandate, CWS has produced this report
