- Shape
- Asymmetrical vane with a rounded tip; the trailing vane is significantly broader than the leading vane. The overall outline is slightly curved and elongated.
- Size

Description
This is a sleek, black feather from an American Crow. The bird is entirely black with a heavy bill and a short, squared-off or slightly rounded tail. Crows are known for their intelligent eyes and acrobatic flight.
Colour & Pattern
Uniformly iridescent black on the dorsal surface with a subtle violet or blue-green sheen visible in direct light. The ventral (underside) surface is a more matte, charcoal gray. There are no bands or spots.
Barb Structure
Densely interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, transitioning to loose, plumulaceous (downy) barbs at the base (quill area).
Texture & Surface
Smooth, stiff, and slightly oily to the touch for water repellency. The surface has a high-quality semi-gloss finish typical of healthy corvids.
Key Features
Solid black coloration, subtle iridescence, asymmetrical wing-feather shape, and a dark rachis throughout the length of the feather.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, urban parks, shorelines, and suburban residential areas.
Geographic Range
Widely distributed across North America, from southern Canada throughout the United States to northern Mexico. Non-migratory in most areas, though northernmost populations may move south.
Ecological Role
Generalist omnivore and scavenger. They play a vital role in cleaning up carrion and controlling insect populations, but also act as nest predators.
Similar Species
Common Raven (larger, more lanceolate), Fish Crow (nearly identical, requires size/audio context), and Steller's Jay (smaller, bluer tones).
Interesting Facts
Crows are among the most intelligent animals on Earth, capable of using tools, recognizing individual human faces, and mourning their dead in 'funerals'.
Condition Notes
Good to Fair. There is some slight separation of the barbs (zipper effect) and minor fraying at the tip, suggesting a naturally molted feather rather than one lost to predation.
