Alaska Yukon Delta Nest Population Size and Potential Production of Geese and Spectacled Eiders on the Yukon-Kuskokwim Delta, Alaska, 1985-2016 The Spectacled Recovery Plan identified annual nesting surveys as the primary method to assess recovery status for Alaska’s Yukon-Kuskokwim Delta (YKD) subpopulation. In addition to documenting population status for spectacled eiders, the survey provides annual information on egg production, nesting effort, phenology, and habitat use for three other focal species including cackling geese, emperor geese, and greater white-fronted geese. Numbers of nests of the four species are stable or increasing in the short-term (2007-2016) and long-term (1985-2016). In 2016, the estimated number of spectacled eider nests (9,464) was the second highest in the history of the survey, but nest success was poor and clutch size very...
