The Marbled Murrelet (Brachyramphus marmoratus) is a seabird in the Alcid family whose populations have declined over the last 30-50 years because of anthropogenic activities including oil spills, gill net fishing, and particularly the loss and fragmentation of nesting habitat Official Status: Threatened, the marbled murrelet is Federally listed under the Endangered Species Act as a threatened species in Washington, Oregon and California, and State-listed as endangered in California and as threatened in Oregon and Washington.Critical habitat is designated for the species and a new proposal for critical habitat is available for review.
