This is a comparison of nesting bird abundance at Cape Espenberg in the 1970's to nesting bird abundance at Cape Espenberg in the 1990's. Nineteen species were found to have decreased in nesting abundance between the 1970's and the 1990's. These species included red-throated loons, common eiders, oldsquaws, semipalmated sandpipers, western sandpipers, arctic terns, and lapland longspurs. Five species were found to have increased in nesting abundance between the 1970's and the 1990's. these species included tundra swans, sandhill cranes, and yellow wagtails. Also included is a comparative study of productivity and populations of western sandpipers in western Alaska. This study showed that western sandpipers in Cape Espenberg have smaller clutcher, smaller eggs, and lower nesting success than western sandpipers in Nome.
