Description

A solid black feather from a Large, intelligent passerine. The American Crow is an all-black bird with a thick bill, broad wings, and a short, rounded tail. They have a distinctive 'caw-caw' vocalization and are often seen in social family groups.

Colour & Pattern

Uniformly iridescent black/charcoal with a subtle violet-blue or greenish sheen visible under direct light (structural color). The ventral surface is more matte gray-black.

Barb Structure

Densely packed pennaceous barbs along most of the vane for aerodynamic stability; plumulaceous (downy) barbs present at the very base for insulation.

Texture & Surface

Smooth, firm, and slightly glossy on the dorsal side. The vane is somewhat stiff to withstand wind pressure but flexible enough for agile flight.

Key Features

Uniform black coloration, iridescent sheen, rounded secondary tip, and a stout rachis that darkens distally.

Habitat

Extremely versatile: found in open woodlands, agricultural fields, city parks, shorelines, and suburban yards.

Geographic Range

Widespread across North America from southern Canada to northern Mexico. Permanent resident in most of its range, with northern populations migrating slightly south.

Ecological Role

Omnivorous scavenger and predator; they play a vital role in cleaning up carrion and controlling insect populations, but can also impact other bird nests.

Similar Species

Common Raven (larger, more pointed feathers), Fish Crow (nearly identical, requires size/voice comparison), European Starling (much smaller, glossier with spots).

Interesting Facts

Crows are known for their exceptional intelligence, capable of using tools, recognizing individual human faces, and mourning their dead in communal gatherings.

Condition Notes

Good condition; slight feather wear/fraying at the tip and trailing edge suggests it was molted naturally at the end of a breeding season.
