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
- Asymmetrical with a rounded tip. The trailing vane is significantly broader than the leading vane, with a slight inward curve (bowing) typical of wing feathers that provide lift.
- Size
- Approximately 5.5 to 6.5 inches (14-16.5 cm) in length. This is consistent with a secondary feather for a medium-large passerine like an American Crow.
- Rarity
- Very Common; one of the most widespread and frequently encountered birds in North America.

Description
A classic 'all-black' bird, the American Crow is a large, intelligent passerine with a thick neck and heavy bill. In flight, they show broad wings with fingered primaries and a squared-off tail. Their feathers are renowned for a purple or blue iridescence in fresh plumage, which fades to a duller black or brown-black as they age before the annual molt.
Colour & Pattern
Uniformly iridescent black/charcoal with a brownish-sepia tint visible under direct light (likely due to moderate sun bleaching). The ventral (under) side appears slightly more matte and gray than the dorsal side.
Barb Structure
Pennaceous and tightly interlocked throughout most of the vane for aerodynamic integrity, transitioning to plumulaceous (downy) at the very base for insulation.
Texture & Surface
Smooth and glossy on the dorsal surface with a subtle oily sheen; stiff and resilient vane structure. The margin of the leading edge is slightly firmer than the trailing edge.
Key Features
Solid black coloration without banding, deep brownish-black rachis, asymmetrical secondary shape, and the presence of a distinct downy base.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, city parks, shorelines, and suburban residential areas.
Geographic Range
Year-round resident across most of North America from southern Canada to northern Mexico. Northernmost populations may migrate short distances south in winter.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations, though they also impact songbird populations by predating nests.
Similar Species
Common Raven (larger, more pointed feathers), Fish Crow (nearly identical, requires size/voice comparison), and Brewer's Blackbird (much smaller and more iridescent).
Interesting Facts
Crows are among the world's most intelligent animals, capable of tool use, recognizing individual human faces, and complex problem-solving. They are highly social and often roost in thousands during winter.
Condition Notes
Fair to Good. The feather shows signs of wear, particularly the separations in the distal barbs (fraying), and slight brownish 'sun-baking' or weathering, suggesting it was molted naturally after a full season of use.
