Recommendations for Establishing Population Objectives for Sea Ducks

No population objectives are listed for any sea duck population in the most recent (2004) update
or earlier versions of the Plan. The primary reason for lack of sea duck objectives is a lack of
reliable abundance estimates, confounded by inadequate knowledge of sea duck distribution for
some species.
Following a 2008 SDJV progress report to the NAWMP Plan Committee, the PC acknowledged
the need to establish population objectives for sea ducks and stated that this need should be

Investigating the wintering ecology of surf scoters and long-tailed ducks

North American populations of breeding surf scoters and long-tailed ducks appear to be decreasing. Along the Atlantic coast, wintering populations of surf scoters are suspected to be decreasing, while the status of wintering populations of long-tailed ducks remains unknown. These trends have led conservation organizations to assign a "high" relative conservation priority to both species.

Barrows Goldeneye Assessment

More than 90% of the world’s population of Barrow’s Goldeneye (Bucephala islandica) breeds from central Alaska to northern California (Robert et al. 2000). The species also breeds in Iceland, where the population is estimated at approximately 2000 birds (Robert et al. 2000). There has also been a small population associated with eastern North America, however, historically, breeding records have been sparse and, in many cases, unconfirmed (Bellrose 1980). Robert et al.

Origin and Availability of Large Cavities for Barrow’s Goldeneye (Bucephala islandica), a Species at Risk

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.

Stellers Eider Survey Near Barrow Alaska

The Alaska breeding population of Steller’s
Eider (Polysticta stelleri) was classified as
threatened under the Endangered Species Act in
June 1997 (USFWS 2002). Recent records suggest
that the species’ current breeding range in northern
Alaska has been greatly reduced and now is
restricted mostly to the vicinity of Barrow
(Quakenbush et al. 2002). Results of aerial surveys
in the past decade verify this distribution pattern
(e.g., Larned et al. 1999, Obritschkewitsch et al.
2008, Ritchie and King 2001).

Key Marine Habitat Sites for Migratory Birds in Nunavut and the Northwest Territories.

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
identifying key marine habitat
