American Crow (Common Crow)
Primary flight feather (remex), likely from the mid-to-outer wing (P5-P7 range)

American Crow (Common Crow)

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: brachyrhynchos

Family: Corvidae (Crows, Jays, and Magpies)

Shape
Asymmetrical with a narrower leading edge (outer vane) and a broader trailing edge (inner vane). The tip is rounded and shows slight emargination (narrowing) characteristic of large corvids.
Size
Estimated at 18–22 cm (7–8.5 inches) long. This is consistent with the primary feathers of a standard adult American Crow.
Rarity
Very Common; one of the most widely recognized and abundant birds in North America.

Description

A large, all-black passerine with a heavy bill. This feather is a primary wing feather, essential for the crow's strong, steady flapping flight. The bird is known for its high intelligence and social complexity.

Colour & Pattern

Uniformly iridescent black/charcoal with no banding. Under direct light, it may show a subtle violet or blue-green sheen. The ventral (underside) surface is more matte gray-black compared to the glossier dorsal surface.

Barb Structure

Tightly interlocked pennaceous barbs throughout most of the vane for flight efficiency, transitioning to a small amount of downy plumulaceous structure at the very base near the calamus.

Texture & Surface

Stiff and smooth with a slight oily gloss. The vane is rigid to withstand the aerodynamic pressures of sustained flight.

Key Features

Uniform black coloration, distinct asymmetry of the wing feather, rounded tip, and a stout, dark rachis that pales at the base.

Habitat

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

Geographic Range

Widespread across North America from southern Canada throughout the United States to northern Mexico. Generally a year-round 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. They are also highly sensitive to West Nile Virus.

Similar Species

Common Raven (larger, more pointed feathers), Fish Crow (nearly identical, requires size/geographic context), or Boat-tailed Grackle (smaller, different iridescence).

Interesting Facts

Crows are capable of recognizing individual human faces and can communicate specific threats to other members of their flock using a variety of 'caws'.

Condition Notes

Good condition; shows some minor wear and 'fingering' at the edges of the inner vane, possibly from a naturally molted feather at the end of a season.
