American Crow (Common Crow)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus brachyrhynchos
Family: Corvidae (Crows, Ravens, and Jays)
- Shape
- Highly asymmetrical vane typical of outer flight feathers; the leading edge is much narrower than the trailing edge. The tip is slightly rounded with a subtle distal taper.
- Size
- Estimated 7.5 to 9 inches (19-23 cm) in length. This is consistent with the primary feathers of a medium-large passerine like an American Crow.
- Rarity
- Very Common; one of the most widely recognized and populous bird species in North America.

Description
This is a sleek, sturdy primary feather from an American Crow. The bird itself is entirely black, including the bill and legs. Crows are famous for their intelligence, social complexity, and 'caw-caw' vocalizations. In flight, they show broad, rounded wings with 'fingered' wingtips.
Colour & Pattern
Uniformly deep black/iridescent black on the dorsal surface. Under certain lighting, it may show a subtle blue or purple sheen (structural color). The ventral (underneath) side is slightly more matte, grayish-black.
Barb Structure
Pennaceous; tightly interlocked barbs with well-developed barbules and hooklets providing a wind-resistant surface. The base shows a small amount of plumulaceous (downy) structure near the calamus.
Texture & Surface
Smooth, stiff, and glossy. The surface has a waxy appearance that aids in water repellency and aerodynamic efficiency.
Key Features
Solid black coloration without banding; high asymmetry of the vanes; stiff, glossy texture; size range distinct from smaller blackbirds and larger ravens.
Habitat
Extremely versatile: found in open woodlands, agricultural fields, city parks, suburban yards, and landfills. They prefer areas with both open ground for foraging and trees for nesting/roosting.
Geographic Range
Widespread across most of North America, from southern Canada 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. They are also highly sensitive to West Nile Virus, serving as an indicator species.
Similar Species
Common Raven (larger, more wedge-shaped tail feathers, more heavy rachis), Fish Crow (nearly identical, requires size/auditory comparison), or Brewers Blackbird (much smaller).
Interesting Facts
Crows are known to use tools, recognize individual human faces, and hold 'funerals' where they gather around a deceased member of their species to learn about potential threats.
Condition Notes
Good to Excellent. The vanes are mostly intact with very minor ruffling at the trailing edge. The clear calamus suggests a healthy molt rather than a forced removal.
