- Shape
- Relatively symmetrical vane with a rounded tip; the inner vane is slightly broader than the outer vane, typical of secondary feathers.

Description
This is a sleek, black flight feather from the American Crow, a highly intelligent songbird. The bird itself is entirely black with a heavy bill and a fan-shaped tail in flight. Known for their complex social structures and 'caw' vocalizations.
Colour & Pattern
Uniformly iridescent black/dark charcoal appearance with a slight brownish-grey gradient toward the base. Features a subtle blue-violet or greenish iridescence when viewed in direct sunlight, common in corvids.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, transitioning to soft, plumulaceous (downy) barbs at the base near the calamus.
Texture & Surface
Smooth, stiff, and glossy on the dorsal surface; the underside has a more matte finish. The texture is designed for durable flight and weather resistance.
Key Features
Uniform black coloration with subtle iridescence, rounded tip, and a prominent sturdy rachis. Lack of white or brownish mottling distinguishes it from raptors or smaller blackbirds.
Habitat
Extremely versatile; found in agricultural lands, open woodlands, suburban parks, city centers, and landfills.
Geographic Range
Widespread across most of North America, from southern Canada throughout the United States to northern Mexico. Generally resident, though northernmost populations may migrate south.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations, but can pressure songbird populations by predating nests.
Similar Species
Common Raven (much larger, more wedge-shaped tail feathers), Fish Crow (nearly identical, identified by call), or Boat-tailed Grackle (more intense iridescence and different proportions).
Interesting Facts
Crows are known to use tools, recognize individual human faces, and even hold 'funerals' for deceased flock members to investigate potential threats.
Condition Notes
Good condition; the vane is largely intact with minor fraying at the tip and edges, likely a naturally molted feather (post-breeding molt). No visible fault bars.
