American Crow
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus brachyrhynchos
Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Asymmetrical vane with a distinctively tapered, rounded tip; the outer vane is much narrower than the inner vane, showing strong aerodynamic adaptation
- Size
- Approximately 7-9 inches (18-23 cm) in length; consistent with mid-sized primaries of an adult Passeriform of this mass
- Rarity
- Very Common; one of the most widespread and easily recognized birds in North America

Description
This feather belongs to the American Crow, a large, all-black passerine with a heavy bill. Crows are known for their intelligent social structures, raucous 'caw-caw' vocalizations, and highly social behavior, often forming massive winter roosts. This specific feather reflects the bird's solid black plumage which acts as a durable, melanin-rich shield against wear.
Colour & Pattern
Uniformly iridescent black with subtle violet or blue sheen visible under direct light; the underside appears slightly more matte gray-black; no banding or white spots present
Barb Structure
Densely interlocked pennaceous barbs designed for flight integrity; the barbules are tightly hooked, though currently separated in segments due to water immersion
Texture & Surface
Smooth and glossy when dry, currently appearing slick and matted due to moisture; the surface has a natural structural iridescence caused by melanin and feather microstructure
Key Features
Solid deep black coloration, significant vane asymmetry indicating a primary wing position, and a lack of white or brown markings characteristic of other corvids
Habitat
Found in a vast array of environments including open woodlands, agricultural fields, urban parks, residential neighborhoods, and coastal regions
Geographic Range
Year-round resident across most of North America from southern Canada to northern Mexico; northernmost populations may move south in winter
Ecological Role
Omnivorous scavenger and predator; they play a vital role in cleaning up carrion and controlling insect populations, while also acting as important seed dispersers
Similar Species
Common Raven (larger, more wedge-shaped tail feathers, shaggier appearance), Fish Crow (nearly identical, identified primarily by voice), or Brewer's Blackbird (much smaller and more iridescent)
Interesting Facts
American Crows are among the most intelligent birds, capable of recognizing individual human faces and passing that information to their offspring; they also utilize tools and solve multi-step puzzles
Condition Notes
Poor to Fair; the feather is saturated with water which has caused the vanes to 'unzip' or separate into several clumps; the rachis appears intact but the structural integrity of the vane is compromised by environmental exposure
