Abstract:

The Marbled Murrelet Brachyramphus marmoratus is a small, diving seabird inhabiting inshore waters of the Northeastern Pacific Ocean. This species feeds on small, schooling fishes and zooplankton, and nests primarily on the moss-covered branches of large, old-growth conifers, and also, in some parts of its range, on the ground. We reviewed existing information on this species to evaluate its current status in the northern part of its range Alaska U.S. and British Columbia Canada. Within the southern part of its range Washington, Oregon, and California, U.S., the Marbled Murrelet was listed as a threatened species under the Endangered Species Act ESA in 1993, and the U.S. Fish and Wildlife Service USFWS needed information on the species throughout its range for ESA deliberations. We compiled published information on the conservation status, population biology, foraging ecology, population genetics, population status and trends, demography, marine and nesting habitat characteristics, threats, and ongoing conservation efforts for Marbled Murrelets in Alaska and British Columbia.
