Likely American Crow (also called Common Crow); identification is tentative from this single dark feather.

A dark, elongated feather consistent with a crow-sized passerine, but its appearance alone is not diagnostic. American Crows are all-black, adaptable birds with broad wings, a distinctive caw, and a varied diet.

Very dark brown to black, with subtle brownish highlights and no clear bands or spots; lighting may obscure sheen and color detail.

Mostly tightly interlocking pennaceous barbs, with a small area of loose, separated barbs near the lower vane; no obvious aftershaft.

A slender pale gray-brown rachis runs to a long, narrow base; dark barbs form a dense vane, with some fraying near the base.

Smooth, matte-to-slightly glossy surface; the vane looks fairly firm, but its basal edge is ragged.

Probably from the wing, based on the elongated shape and firm vane, though a tail feather cannot be ruled out.

Uniform dark coloration, elongated form, and pale shaft; these traits fit several crow-sized birds and do not confirm species.

If from an American Crow, typical habitats include open woodland, farmland, wetlands, parks, and suburbs.

American Crows are widespread across much of the United States and southern Canada, with regional seasonal movements.

Crows are omnivores and scavengers that consume insects, seeds, carrion, and human refuse; American Crow populations are widespread and generally considered stable.

Common Raven feathers are generally larger; grackle feathers may show stronger iridescence, while black vulture feathers can be broader and more worn-looking.

American Crows are highly social, cache food, and can recognize individual human faces.

Crow feathers have appeared in art and craft traditions; possession and use of wild bird feathers may be regulated, so check local laws.

Use a ruler and compare multiple feathers from the same site; record location and check local feather-identification guides rather than relying on black coloration alone.

Fair condition: visible loose or frayed barbs near the base; no clear evidence of active growth or severe damage.
