- Shape
- Slightly asymmetrical vane with a rounded to slightly pointed tip, typical of an outer-mid primary flight feather adapted for soaring and maneuvering.
- Size
- Approximately 7 to 9 inches long, consistent with a medium-to-large sized passerine primary flight feather. Standard primaries for this species typically range from 6 to 10 inches depending on the specific feather slot.

Description
The American Crow is a familiar, intelligent, and highly adaptable black bird known for its caw vocalization and social behavior. Measuring around 17 to 21 inches in length with a robust build, it is entirely black from bill to tail, often flashing iridescent purple and blue in bright sunlight. They are omnivorous generalists capable of problem-solving, tool use, and complex communication within family groups.
Colour & Pattern
Solid deep charcoal gray to matte black with subtle iridescent bluish-purple sheen under direct lighting, typical of corvid melanin-based pigmentation. The ventral side is slightly duller, and the rachis is dark transitioning to a lighter gray-white at the extreme base.
Barb Structure
Pennaceous structure with tightly interlocked barbs and barbules near the leading edge, but showing significant fraying and untangling (loss of hooklets/barbicels) along the trailing vane. No afterfeather is prominently visible.
Texture & Surface
Stiff, durable, and semi-glossy on the dorsal surface, with a slightly matte texture underneath. The leading edge is firm and knife-like to cut through air, while the trailing edge shows wear.
Key Features
Solid black/charcoal coloration with subtle iridescence, stiff flight feather structure, slightly curved rachis, and the distinctive size and proportions matching a medium-sized corvid.
Habitat
Highly adaptable, found in open woodlands, agricultural fields, pastures, parks, golf courses, suburban neighborhoods, and urban centers.
Geographic Range
Widespread year-round resident across most of North America, from southern Canada down through the United States to northern Mexico, with northernmost populations migrating slightly southward in winter.
Ecological Role
Acts as an important scavenger, seed disperser, and predator of small insects and vertebrates. Crows help control pest populations and clean up carrion, serving as a key link in local food webs.
Similar Species
Fish Crow (Corvus ossifragus) and Common Raven (Corvus corax). Fish crow feathers are generally smaller and harder to distinguish visually without direct comparison, while Common Raven feathers are significantly larger and display heavier, broader rachises.
Interesting Facts
Crows have exceptional problem-solving intelligence, are known to recognize human faces, remember individual humans who pose threats, and engage in complex social rituals including holding 'funnels' or gatherings over dead members.
Condition Notes
Fair to poor condition. The feather shows noticeable wear, fraying, and separation of the barbs along the trailing vane, likely due to weathering, ground contact, or physical damage before being molted or dropped.
