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.,...

Broad scale banding of midcontinent greater white-fronted geese (MCWFG) is motivated by the Flyway Management Plan objective to maintain optimum harvest opportunity throughout the population range (Central, Mississippi, and Pacific Flyway Councils, 2023). This objective is accomplished by implementing a harvest strategy whereby changes to bag limits and season dates are dependent upon thresholds of abundance and harvest rate. Such estimates are calculated through Lincoln estimation (Lincoln 1930, Alisauskas et al. 2009, Dooley 2023) that requires annual banding. In addition, banding provides a means to identify changes in harvest distribution. The U.S. Fish and Wildlife Service (USFWS) Migratory Bird Management...

Duck banding data is integral to the Adaptive Harvest Management (AHM) process that uses both band recovery data and aerial breeding population survey data to establish hunting regulatory packages each year. Mallard banding in Alaska is one component of the process to set hunting regulations for ducks in the Pacific Flyway by providing harvest rate estimates for the Western Mallard AHM model (U.S. Fish and Wildlife Service 2021). Harvest rate is used in coordination with breeding population size estimates from the Waterfowl Breeding Population and Habitat Survey to determine the optimal regulatory strategy (liberal, moderate, restrictive, or closed) for dabbling ducks in the Pacific Flyway. Each regulatory alternative...

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...

This project is an annual communicating memo explicitly designed to inform the Pacific Flyway Representative of waterfowl survey results for incorporation of the data into harvest management reports and regulatory processes. This memorandum is additionally shared widely with partners outside the USFWS. The major products are an annual reporting memo–automatically generated from an R Quarto document, and 19 species-specific comma delimited table files that appear in the memo, and the generating qmd code.

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...

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...
