Approximately 95% of the total cackling [Canada] goose population (Branta hutchinsii minima) breed on the Yukon-Kuskokwim Delta (YKD). The U.S. Fish and Wildlife Service has been monitoring cackling geese on the YKD annually since 1998. In 2011, the Pacific Flyway Council and USFWS reviewed procedures that have been used to estimate the fall population size of cackling geese since 1998. Based on that review, the Pacific Flyway Council adopted a new interim monitoring method for estimating populations and recommended that USFWS verify the population estimates using a mark-resight method, focused on capturing cackling geese on the breeding grounds and resighting on the wintering areas. Accordingly, a 3-year program was initiated in 2011. Information from this study should provide an independent assessment of the cackling goose population size.
