The Alaska Trumpeter Swan Survey was an aerial survey conducted by the U.S. Fish and Wildlife Service, Division of Migratory Bird Management, Alaska Region (MBM-AK) and partners to monitor the status of trumpeter swans (Cygnus buccinator) in Alaska. It was first conducted in 1968 and then repeated at five-year intervals from 1975 through 2015. The objectives of the survey were to estimate the abundance, distribution (1968–2005 only), and productivity of trumpeter swans in late summer, when the swans were dispersed on breeding territories and cygnets were large enough to be easily counted from the air. Estimates were obtained for the abundance of white swans (swans >1 year old), cygnets, and total swans, as well...

Between September and November each year, nearly the entire world population of Pacific black brant (Branta bernicla nigricans) stages at Izembek Lagoon and surrounding estuaries (hereafter: Izembek Complex). The Izembek Complex is a unique area of protected brackish waters, supporting one of the world’s largest eelgrass beds and a diverse array of wildlife. The Alaska Fall Brant Survey has been conducted annually since 1976 in late-September through October, to provide an index of abundance for the entire post-breeding Pacific black brant population (Branta bernicla nigricans), while secondarily, providing annual fall population indices for cackling geese (Branta hutchinsii), emperor geese (Anser canagicus), and...

Dusky Canada geese (Branta canadensis occidentalis) comprise one of the smallest populations of geese in North America and their breeding range is limited to Prince William Sound, primarily the Copper River Delta, and Middleton Island, Alaska. The Alaska Region of Migratory Bird Management initiated an aerial breeding pair survey on the Copper River Delta in 1986 after reported declines in the abundance of dusky Canada geese on their nesting and wintering grounds. Since 2008, the Pacific Flyway Council uses results of the aerial breeding pair survey, together with Middleton Island ground counts conducted by the Alaska Department of Fish and Game, as a management index to determine optimal hunting regulations. Survey...

The Yukon-Kuskokwim Delta (YKD) Aerial Breeding Pair Survey provides data on the spring abundance of targeted waterfowl species nesting on the YKD coastal zone in western Alaska. This region supports millions of waterbirds that comprise one of the largest and most important waterfowl breeding grounds in North America, including species of concern such as the red-throated loon (Gavia stellata), emperor goose (Chen canagica), Pacific black brant (Branta bernicla nigricans), common eider (Somateria mollissima), black scoter (Melanitta nigra), long-tailed duck (Clangula hyemalis), and the threatened spectacled eider (Somateria fischeri). The YKD goose, swan, and crane survey was first implemented in 1985 to monitor...

The Waterfowl Breeding Population & Habitat Survey (WBPHS) has been conducted annually since 1955 (1957 in Alaska) by the U.S. Fish and Wildlife Service (FWS) and Canadian Wildlife Service to estimate the spring abundance of targeted waterfowl species in their principal breeding areas of North America. The survey results are used to establish annual hunting regulations in the United States and Canada, monitor population trends, and inform various conservation and management decisions at the state, flyway, and continental levels. The Waterfowl Program in the FWS Division of Migratory Bird Management-Alaska Region (MBM-Alaska) is responsible for surveying strata 1–12 of the WBPHS during May to June of each year (i.e.,...

More than 90% of the Pacific population of Steller’s eider (Polysticta stelleri) spends a portion of the fall in Alaska during fall wing molt and staging period, mostly along the Alaska Peninsula. The long-term Steller’s eiders counts from fall emperor goose surveys have shown declines at Izembek Lagoon and Port Heiden and approximate stability at Seal Islands and Nelson Lagoon (1992-2015, USFWS unpubl. data). Spring surveys for Steller’s eiders have been conducted along the north side of the Alaska Peninsula by USFWS since 1992; fall oblique photographic surveys covering the same area began in 2012.Systematic transect-based “overhead” photography is a method proposed for the fall survey and will be used to generate...

In 1957, Henry (Hank) Hansen and Jim King identified important habitat for molting geese in an area now referred to as the Teshekpuk Lake Special Area (TLSA) in northern Alaska. Located within the larger National Petroleum Reserve-Alaska (NPR-AK), the importance of this habitat was reaffirmed by the Secretary of Interior in 1977 with the designation of the TLSA. In 1976, the Waterfowl Department of U.S. Fish and Wildlife Service (USFWS) Migratory Bird Management-Alaska (MBM-AK) began conducting aerial goose surveys within an area of the TLSA that they designated as the Traditional Survey Area. These surveys continued through 1978, after which there was a three-year hiatus. Surveys began again in 1982 and continued...

Annual assessment of nesting populations of geese on the Yukon-Kuskokwim Delta (YKD) provides information for biologists, participants in cooperative goose management plans, and Pacific Flyway technical committees. A ground-based sampling procedure has been used since 1986 to estimate the number of total nests, active nests, and eggs for cackling geese, emperor geese, greater white-fronted geese, and spectacled eiders. Annual information on the size of the nesting population and potential number of young produced contributes long term data needed to understand goose and eider population ecology and better manage these species. The survey has been the primary method of measuring recovery status for the western population...

The Arctic Coastal Plain Aerial Breeding Pair Survey provides data on distribution, abundance, and trend of 33 bird species that nest in northern Alaska. The survey has been conducted in its current form annually since 2007. Methods follow the standard operating procedures for the Waterfowl Breeding Population and Habitat Survey. Primary uses of the survey data are to evaluate recovery status of Spectacled Eider (Somateria fischeri) and Steller’s Eider (Polysticta stelleri), as well as monitor species of conservation concern including Lesser Snow Goose (Chen caerulescens caerulescens), Yellow-billed Loon (Gavia adamsii), Red-throated Loon (G. stellata), and Black Brant (Branta bernicla nigricans). Survey data are...
