It is most abundant in northern Puget Sound and the Strait of Juan de Fuca, and least abundant along the coast of southwestern Washington. Due to its status as a federally 'threatened'
Adult non-breeding plumage is a black crown with a white ear patch, throat and underside, black nape and back, and black wings with white scapulars (top of wing). The 2015 population estimate for Washington is about 7,500 birds. It is found in marine waters in general proximity to nesting habitat. The goal of the project is to gain a better understanding of marbled murrelet diet during the non-breeding season. Winter adults have brownish-gray upperparts and white scapulars.

Condor 92:1068-1073. It spends the majority of its time on the ocean, restingoosting and feeding, but comes inland up to 80 kilometers (50 miles) to nest in forest stands with old growth forest characteristics. Each species account is written by leading ornithologists and provides detailed information on bird distribution, migration, habitat, diet, sounds, behavior, breeding, current population status, and conservation. The marbled murrelet population in Washington is low and declining. Unlock thousands of full-length species accounts and hundreds of bird family overviews when you subscribe to Birds of the World. KULETZ1, CHRISTOPHER S . Methods of surveying marbled murrelets at inland forested sites. = Marginal Habitat. The marbled murrelet inhabits the nearshore marine environment in western North America. Underparts are light, mottled brown. Marbled Murrelets breed from central California to the western Aleutians, occupy a broader range of coastal habitat, but nonetheless overlap extensively in distribution with Kittlitz’s Murrelet in both core and peripheral parts of their range (Nelson 1997, Day et al.

Habitats used during non-breeding months and migratory rest-stops were not mapped. Project. The main sensitivities of marbled murrelets to climate change will likely be due to potential changes in prey availability and habitat. Since 2000, WDFW has joined USDA Forest Service Pacific Northwest Research Station, U.S. The first actual nest in Washington was found near
The primary factor influencing breeding distribution is likely the availability of suitable nesting "platforms" (such as large branches) within close proximity to marine water foraging areas. By 1995, several million dollars and thousands of work hours have increased the number of known nests to 95, nine of which were in Washington. The first tree nest for Marbled Murrelet was discovered in 1963, near Okhotsk, Siberia. of downy young or eggs in: Whatcom County in 1925, Sultan River Basin in 1950, Rugged Ridge in 1982-3, Aberdeen in 1983, and near
America was discovered in a 200-foot Douglas-fir near Santa Cruz, California. Small schooling fish (such as Pacific anchovy, Pacific herring, candlefish, and Pacific sand lance) make up most of the diet, which may include small crustaceans when fish are not abundant. Metadata
Additional work is slated for 2020, with planned modifications for positioning of boats and crew to address concerns regarding COVID-19. The short term population and distribution objective for the recovery of Marbled Murrelets is that over the period 2002-2032 (three generations) is to halt the decline of the British Columbia (B.C.) Marbled Murrelet. Alterations in nesting habitat, which occurs in inland mature and old growth forests, could also lead to declines in populations. In 1975, the first tree nest in North
Marbled Murrelet are found year round in coastal areas throughout Washington. The green area shows the predicted habitats for breeding only.
Occupancy data show Marbled Murrelets occurring in mature coniferous forests, suggesting nesting activities in these areas.

In Washington, this species is an uncommon resident. Juvenile plumage is similar to adult non-breeding but duskier overall. This species is rare in mature coniferous forests west of the Cascade crest at low to moderate elevation. Northwestern Naturalist 71:72-84. Maps |

Legend: = Core Habitat = Marginal Habitat. WDFW conducts survey flights over a period of several days from November through February annually to monitor the abundance, trends, and distribution of sea ducks and other marine birds, including marbled murrelets, in the Puget Sound and the Strait of Juan de Fuca (U.S. portion of the Salish Sea).

species, the Marbled Murrelet has been the subject of a flurry of research recently. At-sea population monitoring from 2001 to 2015 indicated a 4.4% decline in the murrelet population annually, which represents a 44% reduction since 2001. Hemlock zones west of the Cascade crest, and Interior Western Hemlock just east of Snoqualmie Pass. Next generation sequencing of the DNA in the feces is used to determine what the murrelet was eating. The map illustrates potential range and habitat distribution of this species in Washington. An adult marbled murrelet in non-breeding plumage on marine waters, If you see this species, please share your observation using the, Learn more about this research and access progress reports, Periodic Status Review for the Marbled Murrelet in Washington (2016), Northwest Forest Plan - Marbled Murrelet Monitoring Program, Guidance for identifying terrestrial habitat, Pacific Seabird Group Murrelet Survey Protocol (2003), Cornell Lab All About Birds - Marbled Murrelet, Fish and wildlife habitat loss or degradation, Marbled Murrelet habitat, forest practices and survey guidance. The Marbled Murrelet (Brachyramphus marmoratus) has long been regarded as a bird of mystery in the Pacific Northwest because its nesting habits have remained largely unknown to ornithologists, and its nearshore feeding habits made it difficult to survey.
