Description

This is a sturdy flight feather from an American Crow, a large all-black passerine known for its intelligence. The bird typically reaches 17-21 inches in length with a wingspan of nearly 3 feet. They are social birds, often seen in large murders (flocks).

Colour & Pattern

Uniformly iridescent black or deep brownish-black depending on the light; the dorsal surface has a subtle violet or blue sheen characteristic of corvids, while the ventral side is more matte greyish-black.

Barb Structure

Tightly interlocked pennaceous barbs throughout most of the vane; the base of the feather shows some plumulaceous (downy) structure near the calamus.

Texture & Surface

Smooth and somewhat stiff; the trailing edge is flexible while the leading edge is rigid for aerodynamic stability. It has a glossy, waxy sheen.

Key Features

Solid black coloration with iridescence, asymmetrical vane typical of primary flight feathers, and a robust dark rachis.

Habitat

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

Geographic Range

Common throughout most of North America, from southern Canada to northern Mexico; generally a year-round resident in most of its range.

Ecological Role

Omnivorous scavengers and predators; they help control insect populations and clean up carrion, though they can also impact songbird populations by raiding nests.

Similar Species

Common Raven (much larger, more wedge-shaped tail feathers), Fish Crow (nearly identical, distinguished by call), or Boat-tailed Grackle (smaller, more iridescent/metallic blue).

Interesting Facts

Crows are known to use tools, recognize individual human faces, and have complex social structures. They often work together to 'mob' predators like hawks and owls.

Condition Notes

Good condition; minor fraying at the tip and base consistent with a naturally molted feather (likely post-breeding molt). No significant fault bars or parasite damage visible.
