American Crow
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus brachyrhynchos
Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Asymmetrical vane with a distinct notch (emargination) on the leading edge near the tip; the overall shape is elongated and slightly tapered.
- Size
- Estimated 7-9 inches (18-23 cm) in length. This is consistent with the primary feathers of an adult American Crow, which typically range from 15 to 25 cm depending on the specific wing position.
- Rarity
- Very Common; one of the most widely recognized and abundant birds in North America.

Description
This is a quintessential corvid feather—starkly black, robust, and functional. American Crows are large, intelligent, all-black birds with heavy bills. They are known for their social complexity, 'caw' vocalizations, and ability to use tools. In flight, their wings are broad with rounded tips and characteristic 'fingers' formed by the primary feathers.
Colour & Pattern
Uniformly iridescent black/charcoal. Under direct sunlight, it may show a subtle blue or violet sheen. The underside is slightly more matte gray-black. No banding or spots are present, which is diagnostic for this species.
Barb Structure
Densely packed, interlocked pennaceous barbs throughout most of the vane for flight efficiency; the base shows a small amount of loose, plumulaceous (downy) structure near the calamus.
Texture & Surface
Smooth and stiff with a semi-glossy finish. The leading edge is very rigid to withstand air pressure during flight, while the trailing edge is slightly more flexible.
Key Features
Uniform black coloration, distinct leading-edge emargination, stiff rachis, and the absence of any white or brown mottling common in raptor or owl feathers.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, city parks, suburban yards, and shorelines. They avoid dense, unbroken forests.
Geographic Range
Common throughout most of North America, from southern Canada to northern Mexico. They are year-round residents in most of their range, though northernmost populations may migrate short distances south.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations. They also act as 'sentinels,' alerting other animals to the presence of predators like hawks or owls.
Similar Species
Common Raven (larger, more wedge-shaped tail feathers, more pronounced iridescence), Fish Crow (nearly identical, usually requires vocalization or measurement to distinguish), and Chihuahuan Raven (white feather bases).
Interesting Facts
Crows are capable of recognizing individual human faces and can communicate to their flock whether a person is a threat or a friend. They have been known to leave 'gifts' like pebbles or shiny objects for humans who feed them.
Condition Notes
Good condition. There is minor fraying at the tip and along the trailing edge, suggesting this may have been a naturally molted feather toward the end of its wear cycle. No significant fault bars are visible.
