Range Northwestern Crow is resident along the Pacific coast from south-coastal and southeastern Alaska south through British Columbia west of the Coast Mountains and Cascade Mountains, to northwestern Washington, including the Queen Charlotte Islands, Vancouver Island, and all other coastal islands. Status Fairly common to common summer resident along the coast. Locally abundant to very abundant from late summer through early spring in the vicinity of nocturnal roosts, particularly in the Georgia Depression. Nonbreeding The Northwestern Crow occurs along the length of the British Columbia coastline, including Vancouver Island and the Queen Charlotte Islands.
Numbers dwindle rapidly with increasing elevation and distance from the sea.
This is especially notable on the Fraser, Skeena and Nass rivers. Although the Northwestern Crow is widespread along the coast, its centre of abundance is in the Georgia Depression, including the southeast coast of Vancouver Island and the lower Fraser River valley. The Northwestern Crow occurs at elevations from sea level to 1,700 m, but it is most numerous at lower elevations. Although it frequents a wide range of natural and human-influenced habitats, it is closely linked to marine shorelines, where it forages much of the time. Thus, shallow marine shores with interspersed rocky headlands, boulder beaches, and sand, gravel or mudflats are the primary feeding grounds of this crow.
