American Crow
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: C. brachyrhynchos
Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Asymmetrical vane with a distinctively tapered and slightly rounded tip; the leading edge (outer vane) is significantly narrower than the trailing edge (inner vane), typical of aerodynamic flight feathers.
- Size
- Approximately 7-9 inches (18-23 cm) in length. This is consistent with the primary feathers of a large passerine like an American Crow, which typically range from 6 to 10 inches depending on position.
- Rarity
- Very Common; one of the most abundant and recognizable birds in North America.

Description
The American Crow is a large, all-black passerine with a heavy bill and a short, squared-off tail. This primary feather captures the bird's utilitarian elegance; it is built for powerful, steady flapping flight. Crows are known for their high intelligence, social complexity, and 'caw-caw' vocalizations.
Colour & Pattern
Uniformly iridescent black/charcoal with a brownish-grey wash visible in direct sunlight, typical of weathered or molted feathers. The underside is a more matte greyish-black. No banding or spots are present.
Barb Structure
Densely pennaceous and tightly interlocked with hooklets (barbicels) for flight integrity. Lower base shows a small amount of plumulaceous (downy) barbs near the calamus (quill).
Texture & Surface
Smooth and glossy with a slight structural iridescence (visual sheen) when held to the light. The leading edge is stiff and slightly curved to maintain wing shape during flight.
Key Features
Solid black coloration without barring, asymmetrical flight vane, iridescent sheen, and a size larger than a Blue Jay but smaller than a Common Raven.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, suburban neighborhoods, urban parks, and coastal areas. They generally avoid dense uninterrupted forests.
Geographic Range
Widespread across North America, from southern Canada throughout the United States to northern Mexico. Most populations are year-round residents, though northernmost birds migrate south.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations. They also act as 'sentinels,' alerting other animals to the presence of predators like hawks or owls.
Similar Species
Common Raven (larger, more pointed tip, thicker rachis), Fish Crow (nearly identical, best distinguished by sound/range), and Blue Jay (much smaller, usually contains blue/white/black banding).
Interesting Facts
Crows are capable of facial recognition and can remember specific human faces for years. They are known to use tools, such as using sticks to extract larvae, and they hold 'funerals' where they congregate around a deceased member of their flock.
Condition Notes
Fair to Good; the feather shows significant 'fraying' or 'splitting' along the distal edges (tips), suggesting it was molted after a full season of wear or damaged by contact with vegetation.
