Description

A large, all-black passerine reaching 16-21 inches in length. Crows are famous for their intelligence, social complexites, and 'caw' vocalizations. This feather exhibits the classic soot-black coloration and structural integrity required for their steady, flapping flight style.

Colour & Pattern

Uniformly iridescent black/charcoal in life, appearing brownish-black or 'sepia' in sunlight due to wear; subtle violet or blue-green iridescence may be visible under direct light; underside is slightly more matte gray.

Barb Structure

Densely interlocked pennaceous barbs providing a rigid, aerodynamic surface; plumulaceous (downy) barbs present only at the extreme base near the calamus.

Texture & Surface

Smooth, stiff, and glossy with a slight oily sheen for water resistance; the leading edge is notably firm to withstand air pressure.

Key Features

Solid black/brown-black coloration, distinct asymmetry of flight feather, lack of white or grey banding, and a slight metallic sheen.

Habitat

Highly adaptable; found in open woodlands, agricultural fields, suburban yards, city parks, and shorelines.

Geographic Range

Ubiquitous across North America, from southern Canada throughout the United States to northern Mexico; mostly resident, though northernmost populations may move south.

Ecological Role

Omnivorous scavenger and predator; plays a vital role in cleaning up carrion and controlling insect populations; also a host/victim for West Nile Virus.

Similar Species

Common Raven (larger, more wedge-shaped tail feathers), Fish Crow (nearly identical, distinguished best by voice), or Brewer's Blackbird (much smaller).

Interesting Facts

Crows are capable of facial recognition and can remember individual humans for years; they are known to use tools and pass down knowledge through generations.

Condition Notes

Fair to Good; shows signs of moderate wear and sun-fading (browning), suggesting it was molted naturally at the end of a breeding season.
