American Crow
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus brachyrhynchos
Family: Corvidae (Crows, Jays, and Ravens)
- Shape
- Asymmetrical with a narrower leading edge (outer vane) and a broader trailing edge (inner vane). The tip is rounded, and the overall profile is elongated and slightly curved.
- Size
- Estimated at 18-22 cm (7-8.5 inches) in length. This is consistent with the primary flight feathers of an adult American Crow, which typically range from 15 to 25 cm depending on the specific position on the wing.
- Rarity
- Very Common; one of the most widely recognized and abundant bird species in North America.

Description
This is a sturdy flight feather from an American Crow, a large, all-black passerine known for its high intelligence and social complexity. The bird itself is jet black from bill to talons, with a thick neck and a heavy, slightly hooked beak. In flight, crows have a methodical flapping style and 'fingered' wingtips.
Colour & Pattern
Solid deep black to brownish-black. Under direct sunlight, it may show a subtle violet or blue-green structural iridescence. The ventral (under) side is slightly more matte and grayish-black compared to the glossier dorsal surface. No banding or spots are present.
Barb Structure
Pennaceous; the barbs are tightly interlocked with hooklets (barbicels) providing a stiff, cohesive surface for flight. The base of the feather shows a small plumulaceous (downy) section for insulation. The barbs appear mostly intact with some minor fraying at the tip.
Texture & Surface
Smooth, stiff, and somewhat glossy on the dorsal surface. The leading edge is very rigid to withstand air pressure, while the trailing edge is slightly more flexible. The surface feels dry and clean, typical of a healthy molted feather.
Key Features
Solid black coloration, rounded tip, distinct asymmetry of the vanes, and a thick, dark rachis that turns white only at the very base.
Habitat
Extremely versatile; found in open woodlands, agricultural fields, city parks, shorelines, and suburban yards. They avoid only dense, unbroken forests and treeless deserts.
Geographic Range
Widespread across North America, from southern Canada throughout the continental United States to northern Mexico. Most populations are year-round residents, though northernmost birds may migrate south.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations, but can also impact the nesting success of other birds by preying on eggs.
Similar Species
Common Raven (Corvus corax) feathers are significantly larger and more wedge-shaped; Fish Crow (Corvus ossifragus) feathers are nearly identical but slightly smaller and usually require geographic context or DNA for certain separation.
Interesting Facts
Crows are known to recognize individual human faces and can communicate specific threats to other members of their flock. They are also among the few non-human animals known to manufacture and use tools.
Condition Notes
Good condition. The vane is mostly 'zipped' (interlocked), though there is some wear and separation (splitting) near the tip, likely due to natural feather wear before molting or contact with the ground.
