American Crow (Common Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: brachyrhynchos
Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Asymmetrical with a narrower leading edge (outer vane) and a broader trailing edge (inner vane). The tip is rounded and shows slight emargination (narrowing) characteristic of large corvids.
- Size
- Estimated at 18–22 cm (7–8.5 inches) long. This is consistent with the primary feathers of a standard adult American Crow.
- Rarity
- Very Common; one of the most widely recognized and abundant birds in North America.

Description
A large, all-black passerine with a heavy bill. This feather is a primary wing feather, essential for the crow's strong, steady flapping flight. The bird is known for its high intelligence and social complexity.
Colour & Pattern
Uniformly iridescent black/charcoal with no banding. Under direct light, it may show a subtle violet or blue-green sheen. The ventral (underside) surface is more matte gray-black compared to the glossier dorsal surface.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for flight efficiency, transitioning to a small amount of downy plumulaceous structure at the very base near the calamus.
Texture & Surface
Stiff and smooth with a slight oily gloss. The vane is rigid to withstand the aerodynamic pressures of sustained flight.
Key Features
Uniform black coloration, distinct asymmetry of the wing feather, rounded tip, and a stout, dark rachis that pales at the base.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, city parks, shorelines, and suburban yards.
Geographic Range
Widespread across North America from southern Canada throughout the United States to northern Mexico. Generally a year-round resident, though northernmost populations may move south.
Ecological Role
Omnivorous scavenger and predator; plays a vital role in cleaning up carrion and controlling insect populations. They are also highly sensitive to West Nile Virus.
Similar Species
Common Raven (larger, more pointed feathers), Fish Crow (nearly identical, requires size/geographic context), or Boat-tailed Grackle (smaller, different iridescence).
Interesting Facts
Crows are capable of recognizing individual human faces and can communicate specific threats to other members of their flock using a variety of 'caws'.
Condition Notes
Good condition; shows some minor wear and 'fingering' at the edges of the inner vane, possibly from a naturally molted feather at the end of a season.
