Description

Feathers of the American Crow are iconic for their deep black pigment. The bird itself is a large, intelligent passerine with a thick neck, heavy bill, and broad wings. In flight, they show a fanned, rounded tail and characteristic steady rowing wingbeats.

Colour & Pattern

Uniformly iridescent black with subtle violet-blue or greenish sheen when viewed in direct sunlight. The underside appears more charcoal or matte grey due to the lack of structural light interference.

Barb Structure

Highly pennaceous and interlocked for flight efficiency; exhibits a small plumulaceous section at the base (superior umbilicus) for insulation.

Texture & Surface

Smooth, stiff, and slightly glossy on the dorsal surface; the vane is high-integrity but shows significant separation due to wear or handling.

Key Features

Uniform black coloration, slight iridescence, asymmetrical wing feather shape, and a thick, dark rachis.

Habitat

Extremely versatile; found in open woodlands, agricultural fields, urban parks, shorelines, and suburban residential areas.

Geographic Range

Common throughout most of North America from southern Canada to northern Mexico; generally a year-round resident except in the furthest northern reaches.

Ecological Role

Omnivorous scavenger and predator; they play a vital role in cleaning up carrion and controlling insect populations but can impact other songbird nests.

Similar Species

Fish Crow (nearly identical, identified by call), Common Raven (much larger, more wedge-shaped tail feathers), and Boat-tailed Grackle (smaller, thinner rachis).

Interesting Facts

Crows are known to recognize individual human faces and can communicate complex information about threats to other members of their murder (flock).

Condition Notes

Fair condition; the vane is severely 'zipped' or split (barbs separated), likely due to mechanical wear, wind, or the bird's molting process before it was found.
