Description
This is a classic secondary wing feather from an American Crow. The bird is entirely black, from the bill to the talons, with a sturdy build and a rounded tail. They are known for their high intelligence, social complexity, and distinctive 'caw' vocalizations. Adults have a wingspan of about 33-39 inches.
Colour & Pattern
Uniformly iridescent black with subtle violet or blue-green sheen visible in direct light. The underside is a more matte grayish-black. The rachis is dark but transitions to a lighter, translucent calamus.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, with a small plumulaceous (downy) section at the base (superior umbilicus).
Texture & Surface
Smooth and slightly glossy on the dorsal surface; stiff and resilient. The trailing edge is soft, while the leading edge is firm.
Key Features
Deep black coloration with structural iridescence, broad asymmetrical shape, and a thick, sturdy rachis characteristic of corvids.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, urban parks, shorelines, and suburban yards.
Geographic Range
Widespread throughout most of North America, from southern Canada to northern Mexico. Permanent resident in most of its range, with some northern populations moving south.
Ecological Role
Generalist omnivore and scavenger; plays a vital role in nutrient cycling and seed dispersal. They act as 'sentinels' for other wildlife by mobbing predators.
Similar Species
Common Raven (larger, more lanceolate feathers), Fish Crow (nearly identical, requires size/voice/geographic context), and American Woodcock (smaller, different shape).
Interesting Facts
Crows are capable of facial recognition and can remember individual humans for years. They are also known to use tools, such as using sticks to extract food.
Condition Notes
Good condition; slight mechanical wear along the edges and some separation of the barbs near the tip. The calamus is intact, suggesting a natural molt.
