Likely Northern Mockingbird (also called Mockingbird); identification is tentative.

The feather’s dark shaft and vanes contrast sharply with its pale tip, a pattern that may flash conspicuously when a mockingbird spreads its tail. Northern Mockingbirds are gray, long-tailed songbirds known for varied, repeated song phrases.

Dark brown to black vanes with a conspicuous white or pale terminal patch. This high-contrast pattern is characteristic of mockingbird tail feathers, but is not exclusive to them.

Compact pennaceous vanes; barbs appear largely intact, though fine barbule details are not resolvable.

Pale central rachis runs nearly the feather’s full length; dark barbs form most of the vane, with pale barbs at the tip.

Appears smooth and firm, with a matte-to-slightly-satin finish; surface texture cannot be judged closely from the photograph.

Probably from the tail; the narrow, elongated shape and bold terminal marking suggest a rectrix rather than a body feather.

The strongest clue is the dark rectrix with a broad white terminal area. Similar patterns occur in other birds, so shape and color alone do not establish species.

Northern Mockingbirds use open, brushy and developed habitats, including gardens, parks, scrub, and woodland edges; they nest in shrubs or small trees.

Common across much of the United States, Mexico, and parts of the Caribbean; many populations are resident, with some local seasonal movements.

Mockingbirds eat insects and fruit, acting as insect predators and occasional seed dispersers. The species is widespread and generally common; this feather alone provides no population or conservation information.

Loggerhead Shrike and some other black-and-white songbirds can have contrasting tail feathers; compare feather length, tip pattern, and local species. A photograph alone cannot rule them out.

Mockingbirds can imitate songs and other sounds, often repeating phrases in long sequences; males may sing through much of the year.

Feathers may be used in art or crafts, but wild bird feathers are legally protected in many jurisdictions. In the United States, possession of most native bird feathers is restricted under the Migratory Bird Treaty Act.

Record the exact length and photograph both sides beside a scale; note nearby birds and habitat. Avoid collecting feathers where local wildlife laws prohibit possession.

Appears largely intact, with no obvious major breakage or staining; condition is difficult to grade from this view.
