Description

A solid black feather from a large, intelligent passerine. The American Crow is an entirely black bird 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 dorsally with a subtle violet or greenish sheen visible in direct light; the ventral side is a flatter, matte charcoal grey. No banding or spots present

Barb Structure

Densely interlocked pennaceous barbs throughout most of the vane for flight stability; plumulaceous (downy) barbs at the very base for insulation

Texture & Surface

Smooth and glossy on the upper surface with a slight oily sheen; the vane is relatively stiff and resistant to wind, typical of flight feathers

Key Features

Uniform black coloration, rounded tip, asymmetrical secondary vane width, and the characteristic white calamus at the base

Habitat

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

Geographic Range

Widespread across most of North America, from southern Canada throughout the United States to northern Mexico; generally resident, though northernmost populations may move south

Ecological Role

Omnivorous scavenger and predator; they help control insect populations and clean up carrion, but also disperse seeds across wide areas

Similar Species

Common Raven (larger, more pointed tip), Fish Crow (nearly identical, usually requires bill/voice for field ID), and Brewer's Blackbird (much smaller)

Interesting Facts

Crows are known to use tools and can recognize individual human faces; they often live in large family groups and cooperate to mob predators like hawks and owls

Condition Notes

Good condition; the feather appears freshly molted with minimal wear or fraying. There are no obvious fault bars or signs of parasite damage
