Dept. of Fish and Wildlife "The Marbled Murrelet (Brachyramphus marmoratus) is a small diving seabird of the Alcid family which is on the Federally Threatened Species list, and is state listed as endangered or threatened in California, Oregon, and Washington (Nelson, 1997). Because their nests are dispersed and difficult to locate high in trees of mature coastal forests, most research on overall abundance and reproductive output is conducted at sea, where the birds are concentrated within a few km of shore on the open coast . . . This report summarizes population estimation and productivity indices obtained in the 2002 season and compares these data with earlier research in Oregon."

Their recent listing as a federally threatened species (Federal Register, Oct. 1992) adds a further imperative to learn more of this birds nesting and at-sea biology, population size, and reproductive parameters so that meaningful management and recovery plans may be developed.
