Description

This is a primary flight feather from the American Crow, a large, intelligent, all-black passerine with a heavy bill and broad wings. Known for their 'caw' vocalizations and social complexity.

Colour & Pattern

Iridescent solid black. While it appears matte black in low light, it reveals a subtle violet or blue-green structural iridescence. No banding or spots; the rachis is dark transitioning to a lighter quill.

Barb Structure

Tightly interlocked pennaceous barbs on most of the vane for flight efficiency, transitioning to loose, plumulaceous barbs at the very base (the downy section).

Texture & Surface

Smooth and relatively stiff surface with a slight waxy or glossy sheen. The trailing edge is softer than the leading edge to aid in sound reduction and flight control.

Key Features

Solid black coloration with iridescence, prominent leading-edge emargination (notch), and a stiff, slightly curved rachis characteristic of corvid primaries.

Habitat

Ubiquitous across various landscapes including open woodlands, agricultural fields, urban parks, suburbs, and coastal beaches.

Geographic Range

Resident across almost all of North America, from southern Canada to northern Mexico. Northernmost populations may migrate slightly south in winter.

Ecological Role

Generalist omnivore and scavenger; plays a vital role in cleaning up carrion and dispersing seeds, while also acting as a clever nest predator.

Similar Species

Common Raven (larger, more wedge-shaped tail feathers), Fish Crow (nearly identical, identified better by call), and Rook (found in Europe/Asia).

Interesting Facts

American Crows are highly intelligent, known to use tools, recognize individual human faces, and exhibit complex social behaviors like 'funerals' for deceased flock members.

Condition Notes

Fair to Good condition; shows some 'zipper' separation of the barbs (venting) and slight wear at the tip, likely a naturally molted feather.
