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.,...

Spectacled eiders were listed as Threatened under the ESA in 1993 primarily due to a 96% population decline on the Yukon-Kuskokwim Delta in Alaska (YKD), one of three breeding areas worldwide. The Spectacled Eider Recovery Plan ties recovery criteria to numbers of breeding pairs in each of the three nesting areas (YKD, North Slope, Arctic Russia). Lewis et al. (2019) compared ground-based nest abundance estimates to aerially estimated indicated breeding pairs to provide a means to assess recovery status from detection corrected aerial surveys. He reported that aerial crews detect 30-70% of nesting eider pairs, depending on nesting density; however, nest population estimates used in that study were derived from a...
