Taxonomic Comments
Formerly (e.g., AOU 1983, 1998) treated as two species Corvus brachyrhynchos and C. caurinus Baird, 1858 [Northwestern Crow], but merged based on genomic data that indicate a lack of reproductive isolation with extensive introgression and backcrossing (Slager et al. 2020), clinal variation, and a lack of consistent differences in size, ecology, and vocalizations where the two are in contact in southwestern British Columbia and northwestern Washington (Rhoads 1893, Johnston 1961, Slager et al. 2020) (AOS 2020, 2021). Also known as Common Crow.

Range Extent Comments
This species breeds along the Pacific coast from south-coastal and southeastern Alaska (west to Kodiak south through western British Columbia (including Haida Gwaii and Vancouver Island), and from north-central British Columbia, southwestern Northwest Territories, northern Saskatchewan, northern Manitoba, northern Ontario, south-central Quebec, and Newfoundland south to northwestern Baja California (to Ensenada), central Arizona, southern New Mexico, central and southeastern Texas (to Odessa, San Antonio, and north of Corpus Christi), the Gulf coast, and southern Florida (except the Florida Keys). Winters along the Pacific coast from south-coastal and southeastern Alaska (west to Kodiak Island) south through western British Columbia (including Haida Gwaii and Vancouver Island), and from southern Canada (British Columbia east to Newfoundland) south through the breeding range occasionally to the Florida Keys, and casually to southern Arizona. Introduced and established on Bermuda. Casual in southern Nunavut, northwestern Sonora, and western Chihuahua (AOS 2020).
Ecology & Habitat

Habitat

Open forest and woodland used for nesting and roosting, increasing in urban and suburban areas; open and partly open country for foraging, including agricultural lands, urban areas, orchards, and tidal flats; coastal tidelands near coniferous woodland or forest edge in coastal Alaska and Pacific Northwest; restricted mostly to riparian woodland and adjacent areas in arid regions (AOS 2020).

Ecology

In southwestern Manitoba, spring-summer home range averaged 2.6 sq km; foraging flights from nest averaged 382 m, with infrequent flights longer than 700 m (Sullivan and Dinsmore 1992).

Reproduction

Clutch size 3-7 (usually 4-6). Incubation about 18 days, (?) by both sexes. Young tended by both parents, first fly at 4-5 weeks, disperse at various ages after about 2 months postfledging or stay in natal area. One or two broods annually. Auxilaries (typically young) may help dominant pair (parents) breed (Kilham 1989). Some breeding concentrations may reach 0.8 pairs/ha (Auk 109:609-612).
