American Crow (Common Crow)
Primary flight feather (Remiges); likely P4-P7 based on degree of asymmetry.

American Crow (Common Crow)

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

Family: Corvidae (Crows, Ravens, and Jays)

Shape
Highly asymmetrical vane typical of outer flight feathers; the leading edge is much narrower than the trailing edge. The tip is slightly rounded with a subtle distal taper.
Size
Estimated 7.5 to 9 inches (19-23 cm) in length. This is consistent with the primary feathers of a medium-large passerine like an American Crow.
Rarity
Very Common; one of the most widely recognized and populous bird species in North America.

Description

This is a sleek, sturdy primary feather from an American Crow. The bird itself is entirely black, including the bill and legs. Crows are famous for their intelligence, social complexity, and 'caw-caw' vocalizations. In flight, they show broad, rounded wings with 'fingered' wingtips.

Colour & Pattern

Uniformly deep black/iridescent black on the dorsal surface. Under certain lighting, it may show a subtle blue or purple sheen (structural color). The ventral (underneath) side is slightly more matte, grayish-black.

Barb Structure

Pennaceous; tightly interlocked barbs with well-developed barbules and hooklets providing a wind-resistant surface. The base shows a small amount of plumulaceous (downy) structure near the calamus.

Texture & Surface

Smooth, stiff, and glossy. The surface has a waxy appearance that aids in water repellency and aerodynamic efficiency.

Key Features

Solid black coloration without banding; high asymmetry of the vanes; stiff, glossy texture; size range distinct from smaller blackbirds and larger ravens.

Habitat

Extremely versatile: found in open woodlands, agricultural fields, city parks, suburban yards, and landfills. They prefer areas with both open ground for foraging and trees for nesting/roosting.

Geographic Range

Widespread across most of North America, from southern Canada to northern Mexico. Most populations are year-round residents, though northernmost birds may migrate south.

Ecological Role

Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations. They are also highly sensitive to West Nile Virus, serving as an indicator species.

Similar Species

Common Raven (larger, more wedge-shaped tail feathers, more heavy rachis), Fish Crow (nearly identical, requires size/auditory comparison), or Brewers Blackbird (much smaller).

Interesting Facts

Crows are known to use tools, recognize individual human faces, and hold 'funerals' where they gather around a deceased member of their species to learn about potential threats.

Condition Notes

Good to Excellent. The vanes are mostly intact with very minor ruffling at the trailing edge. The clear calamus suggests a healthy molt rather than a forced removal.
