Abstract
    The rates of occurrence of dead birds were determined for beach and water segment censuses in 1978 and 1979 in the inland marine waters of Washington. There were 110 birds of 25 species found dead on beach censuses. The rates of occurrence of dead birds were low in comparison with other studies: beach censuses--0 to 1.47 birds/km; aerial-shoreline censuses--0 to 4.7 birds/103 km; aerial-open water censuses--0 to 9.0 birds/103 km; ferry-shoreline censuses--0 to 6.9 birds/103 km; and ferry-open water censuses--0 to 9.3 birds/103 km. The rates of occurrence of dead birds on study area beaches were decidedly lower than comparable values from Washington beaches facing the Pacific Ocean. Aircraft, small boat, and ferry observation rates were much lower than beach rates.
