Description
A large, all-black passerine with a heavy bill and a short, squared-off or slightly rounded tail. Known for their intelligence and highly social 'murders' or flocks. They have a steady, rhythmic wingbeat and a distinctive 'caw-caw' vocalization.
Colour & Pattern
Uniformly iridescent black to deep charcoal-brown; shows a subtle violet or blue sheen under direct light (structural coloration); the underside (ventral) is more matte and greyish
Barb Structure
Densely pennaceous throughout the majority of the vane for aerobic efficiency; plumulaceous (downy) at the very base near the calamus for insulation; barbs are tightly interlocked by barbules
Texture & Surface
Smooth, glossy, and slightly stiff; the surface has a waxy feel providing some water resistance; the leading edge is firm to cut through the air
Key Features
Solid black coloration with iridescent sheen; asymmetrical wing feather shape; sturdy black rachis; lack of any white or grey markings even at the base of the barbs
Habitat
Extremely versatile; found in open woodlands, agricultural fields, urban parks, suburban yards, and shorelines
Geographic Range
Year-round resident across most of North America, from southern Canada throughout the United States to northern Mexico
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations; they are also highly susceptible to West Nile Virus.
Similar Species
Common Raven (larger, more pointed tip), Fish Crow (nearly identical, requires size/voice/location for distinction), or Boat-tailed Grackle (more tapered and glossier)
Interesting Facts
American Crows are among the most intelligent animals, capable of using tools, recognizing individual human faces, and mourning their dead in 'funerals'.
Condition Notes
Good condition; minor fraying at the tip and along the trailing edge suggests it was naturally molted; no visible fault bars or parasite damage
