Likely American Crow (also called the Common Crow); identification is tentative from the image alone.

This dark, broad feather is consistent with a crow-sized bird, but a single unmarked black feather is rarely species-diagnostic. American Crows are large, all-black birds with a stout bill, familiar caw, and adaptable habits.

Predominantly black to very dark brown, with subtle sheen and lighter brown-gray basal down. No clear bars or spots are visible; lighting may affect apparent color.

Mostly tightly interlocking pennaceous vanes; the base near the fingers appears loose or downy. Some barb tips may be worn or separated.

A straight, dark central rachis divides the vanes; barbs lie closely spaced and slant from the shaft, with the broader vane on one side.

Smooth, matte-to-slightly glossy surface with a firm vane and softer basal portion; no clear powdering is visible.

Probably wing, based on its broad, coherent vane and asymmetric outline; a tail feather cannot be excluded.

Uniform dark coloration, robust shaft, and broad flight-feather-like vane support a crow or similarly sized blackbird; the photo does not show diagnostic species markings.

If from an American Crow, likely source habitats include open woodland, farmland, parks, and suburbs, often near trees used for roosting or nesting.

American Crows are widespread in much of North America; many are resident, while northern birds may move south seasonally.

American Crows are omnivorous scavengers and predators of invertebrates, eggs, and small animals; they are widespread and adaptable, with no global conservation concern.

Common Raven, fish crow, grackle, and black vulture feathers may be similar. Size, rachis and vane proportions, and comparison with a complete set of known feathers are needed for separation.

American Crows are highly intelligent, use varied calls, and can recognize human faces; they also gather in large communal winter roosts.

Crow feathers appear in art and craft traditions, but possession and use of native wild-bird feathers may be regulated; check local laws and avoid collecting protected species.

Photograph both surfaces beside a ruler and compare shape with reference collections; note where it was found, but do not assume the nearest bird dropped it. Check local feather-collection rules.

Appears largely intact, with possible minor fraying near the tip and loose basal down. Overall condition: good; age and molt status cannot be reliably assessed.
