American Crow
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus brachyrhynchos
Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Relatively asymmetrical vane with a broad, rounded tip. The leading edge (outer vane) is narrower than the trailing edge (inner vane), but lacks the extreme emargination found in more distal primaries.
- Size
- Estimated at 5.5 to 7 inches (14-18 cm) in length. This is consistent with the typical wing feather size for a medium-sized corvid.
- Rarity
- Very Common. One of the most ubiquitous and easily observed birds in North America.

Description
The American Crow is a large, all-black passerine with a heavy bill and a short, squared-off or slightly rounded tail. This feather reflects the bird's overall coal-black plumage, which serves as a canvas for a beautiful purple or blue-green iridescent sheen in sunlight. Known for their intelligence and 'caw-caw' vocalizations, crows are highly social and often seen in large family groups or winter roosts.
Colour & Pattern
Uniformly iridescent black with subtle violet or blue-green sheen when viewed in direct light. The underside is slightly more matte, grayish-black. The rachis is dark, matching the vane.
Barb Structure
Densely interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, transitioning to a small plumulaceous (downy) section at the base of the calamus.
Texture & Surface
Smooth, glossy, and slightly stiff. The surface has a structural iridescence common to corvids, appearing velvety but feeling rigid to the touch.
Key Features
Uniform black coloration, rounded tip without sharp points, structural iridescence, and a relatively straight, robust rachis.
Habitat
Extremely versatile; found in open woodlands, agricultural fields, orchards, suburban parks, and urban centers. Generally avoids dense, unbroken coniferous forests.
Geographic Range
Widespread across North America from southern Canada to northern Mexico. Permanent resident across most of the United States.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion, controlling insect populations, and dispersing seeds, though they can impact smaller bird populations through nest predation.
Similar Species
Common Raven (larger, more pointed tip), Fish Crow (nearly identical, requires size comparison or vocalization context), or Boat-tailed Grackle (more tapered, different iridescence).
Interesting Facts
American Crows are among the most intelligent animals in the world, capable of problem-solving, tool use, and even recognizing individual human faces for years.
Condition Notes
Good condition. The barbs are mostly intact with minor separation near the base (splitting). The calamus is clear, suggesting it was naturally molted rather than plucked.
