American Crow

This is a large, sturdy primary feather from an American Crow. The crow itself is an all-black passerine with a heavy bill and a fan-shaped tail in flight. They are known for their high intelligence, social complexity, and 'caw-caw' vocalizations. Adults have a distinctive purplish iridescence on their feathers which helps distinguish them from juveniles, which have more brownish-black plumage.

Uniformly iridescent black with a subtle violet or blue sheen visible in direct light. The underside is slightly more matte gray-black. The calamus is semi-translucent, transitioning into a dark rachis.

Mostly pennaceous and tightly interlocked for aerodynamic flight, transition to plumulaceous (downy) structure near the base of the calamus. The barbs are stiff and intact with visible barbicels.

Smooth and glossy on the dorsal surface due to structural coloration; stiff and rigid to the touch. The trailing edge is slightly softer than the leading edge.

Solid black coloration with iridescence, strong asymmetry of the vanes, and a deep emargination on the outer vane typical of the Corvus genus.

Extremely versatile: found in open woodlands, agricultural fields, urban parks, shorelines, and suburban yards. Avoids only dense, unbroken coniferous forests.

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

Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations. They also act as sentinels for other wildlife, mobbing predators like hawks and owls.

Common Raven (Corvus corax) feathers are significantly larger and have a more oily sheen; Fish Crow (Corvus ossifragus) feathers are nearly identical but slightly smaller and require geographical context or DNA for definitive separation.

American Crows are capable of facial recognition and can remember individual humans for years. They are also known to use tools, such as using sticks to extract larvae from wood.

Good condition. There is minimal wear on the edges, suggesting it may be a relatively fresh molt. The calamus is intact, indicating it was likely shed naturally during a molt cycle.
