Likely Black-billed Magpie (also Pica magpie); identification is tentative from this single feather.

The specimen is a contrasting dark-and-white feather, but it lacks enough visible detail for a dependable species-level match. Black-billed Magpies are large, long-tailed black-and-white corvids with iridescent wings and conspicuous chatter.

Dark brown-black upper portion and cream-white lower vane, with a few pale curved marks near the transition. Lighting and image resolution limit assessment of true hue or any sheen.

Pennaceous, interlocking vanes; some barbs near the pale lower section appear separated or displaced. No clear aftershaft is visible.

A slender, pale rachis runs through the feather; barbs form a dark upper vane and pale lower section, with some loose-looking barbs near the shaft.

Mostly smooth, matte-looking pennaceous surface; the vane is somewhat disrupted near its pale section.

Possibly from a black-and-white body or wing region; the contrasting dark and white areas alone do not establish placement.

Strong dark-to-white contrast, pale rachis, and tapered outline; these traits are shared by many birds and are not diagnostic by themselves.

If a magpie, it favors open country, grasslands, shrublands, and agricultural edges, often with scattered trees and nearby water.

Black-billed Magpies occur chiefly in western and northwestern North America and are generally resident, with some local movements.

Magpies are omnivorous scavengers and predators of invertebrates and small animals, and can influence local food webs; conservation status varies by species and region.

Other magpies, jays, and black-and-white corvids can look similar in isolated feathers; exact vane pattern, feather position, and locality are needed to distinguish them.

Magpies are intelligent, social corvids; Black-billed Magpies often forage on the ground and may follow large mammals or livestock for food.

Feathers have broad artistic and cultural uses, but identification is uncertain; many native bird feathers are legally protected, so collection or trade may be restricted.

Photograph both sides beside a ruler and note where it was found; compare with verified regional feather references rather than relying on color alone.

Appears partly intact, with some displaced or separated barbs; no clear evidence of active growth, parasites, or major breakage is visible.
