American Common Eider Banding Assessment Brad Allen (ME DIFW) Dan McAuley (USGS) Guthrie Zimmerman (USFWS)
Background: • Common eider banding has been occurring in the northern portion of the Atlantic Flyway for many years • Concerns have been raised about decreasing population trends, sporadic disease outbreaks and changes in survival/harvest potential
Background: • Highest priority need identified by Environment Canada’s Monitoring Strategy for American Common Eider is to provide information to ensure that harvest is sustainable: • Better estimates of population size • Survival • Productivity • Harvest rate & derivation
Background: • Eider banding was regularly conducted in Nova Scotia, the coast of Labrador and the St. Lawrence Estuary. • A comprehensive analysis of the data has not occurred. • Funding to continue eider banding has not been secured.
Objectives of Assessment: • Update the analysis conducted by Krementz et al. (1996, Survival and Recovery Rates of American Eiders in Eastern N.A.) for Maine and include males in the current approach. • Determine whether there are trends in survival rate estimates, over what time periods and/or geographic areas. • Use the results from Maine to engage the larger eider banding community to conduct a more comprehensive, regional analysis of the banding data.
Objectives of Assessment: • Incorporate the results into the SDJV effort to assess eider harvest potential. • Use the results to facilitate a larger discussion on the next steps/priority information needed to support eider harvest management. • Incorporate needs into the SDJV Implementaiton Plan Update to provide greater focus in support of harvest management.
