American Crow (also known as the Common Crow)
Primary flight feather (Remiges); likely an outer primary (P7-P9) due to the significant asymmetry

American Crow (also known as the Common Crow)

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

Family: Corvidae (Crows, Jays, and Magpies)

Shape
Highly asymmetrical; elongated and tapered with a slightly rounded tip and prominent emargination (notching) on the leading edge to reduce drag
Size
Estimated 22-26 cm (8.5-10.2 inches) in length; consistent with the primary feathers of an adult American Crow
Rarity
Very Common; one of the most widely distributed and easily recognized birds in North America

Description

Large, coal-black birds with heavy bills and short, square tails. They are highly intelligent social birds known for their 'caw' vocalizations and complex problem-solving abilities

Colour & Pattern

Uniformly iridescent black with subtle violet or blue-green structural sheen visible in direct sunlight; the ventral (under) side is slightly more matte gray-black

Barb Structure

Densely interlocked pennaceous barbs throughout most of the vane for flight rigidity, transitioning to a small plumulaceous (downy) section at the base (superior umbilicus)

Texture & Surface

Smooth, stiff, and glossy; the leading edge is notably more rigid and tightly bound than the trailing edge to withstand air pressure

Key Features

Solid black coloration with iridescent sheen, significant vane asymmetry, and a stiff black rachis; lacks the heavy 'bristly' throat feathers and wedge-shaped tail of the Raven

Habitat

Highly adaptable; found in open woodlands, agricultural fields, orchards, suburban parks, and urban centers

Geographic Range

Widespread across North America, from southern Canada throughout the United States to northern Mexico; most populations are year-round residents

Ecological Role

Omnivorous scavenger and predator; plays a vital role in nutrient cycling and seed dispersal, though can impact songbird nest success

Similar Species

Common Raven (much larger, more violet sheen, more tapered tip) and Fish Crow (virtually identical, requires vocalization or size comparison to distinguish)

Interesting Facts

American Crows are known to recognize individual human faces and can communicate 'dangerous' people to other members of their flock

Condition Notes

Good condition; showing slight wear on the trailing edge (fraying) and some dirt/debris near the quill, likely a post-breeding molt specimen
