Virtually identical to American Crow, from which it is best separated by voice. Predominantly coastal, this is a small, all-black crow with stout, black bill and slightly rounded tail. Slightly smaller than typical American, but note that coastal populations of American Crows along the Oregon and Washington coasts are as small or smaller.
Length: 41 (cm) Wingspan: 86 (cm)
Khaa, khaa, like American but lower pitched, more nasal, slightly faster. Adjacent populations of American Crow sound virtually identical to Northwesterns.
Associated with tidal flats and tide pools, along with forested shorelines, dumps, and towns.
Frequently stores food (usually during low tide) to consume later. Forages on the ground. Breaks shelled foods by dropping on hard surfaces. Flocks outside of breeding season.
Diet consists of invertebrates, fish, amphibians, snakes, small mammals, bird eggs and nestlings, fruit, seeds, and carrion.
So in my opinion Northwestern Crows (Corvus Caurinus) are not a real species and instead a subspecies of the American Crow (Corvus Brachyrhynchos) meaning here in WA we have Pacific American Crow (Corvus Brachyrhynchos Hesperis) and ex Northwestern or as I call them Alaskan American Crows (Corvus Brachyrhynchos Caurinus) around Olympic Peninsula thru Port Townsend, Comaino Island, Northern Whidbey Island, San Juan Islands, Western Skagit and Whatcom Counties. Hybrids along rest of Coast and into the Puget Sound Region usually not found over 10 miles from the Sound. * Eastern American Crow (Corvus Brachyrhynchos Brachyrhynchos) seen across most of U.S. rarely occur in the NW esp at Coast with best potential in the fall-early spring.
Citation: Personal Experience. I observe this regularly, highly confident.
