Black-billed Magpie

This feather belongs to one of the most striking members of the crow family. The Black-billed Magpie is a large, long-tailed bird with bold black-and-white plumage and iridescent green-blue wings and tail. In flight, these white primary patches create a flickering 'white flash' effect that is unmistakable.

Bicolored. The outer vane and distal half of the inner vane are a deep, matte blackish-brown (which appears iridescent blue-green in life). The proximal half of the inner vane features a stark, bright white patch. The ventral (underside) is reflective and lighter.

Mostly pennaceous and tightly interlocked for flight efficiency. The base (calamus area) shows some plumulaceous (fluffy) downy barbs for insulation. Individual barbs are visible and intact.

Smooth and stiff on the pennaceous vanes; the surface has a slight sheen but appears more matte in indoor lighting. The leading edge is firm and designed to cut through air.

Bold white patch on the inner vane contrasting with dark tips, asymmetrical vane width characteristic of flight feathers, and a pale, sturdy rachis.

Open woodlands, meadows, riparian thickets, and suburban areas. They prefer areas with scattered trees for nesting and open ground for foraging.

Common across the western half of North America, from south-central Alaska and western Canada down through the Great Plains to the Southwestern United States.

Omnivorous scavengers and predators. They play a role in pest control by eating insects and ticks (often off large mammals) and help disperse seeds, though they also raid nests of smaller birds.

Eurasian Magpie (Pica pica) feathers are almost identical but geographically separated. Yellow-billed Magpie feathers are similar but restricted to California. Blue Jay feathers are smaller and blue-toned, lacking the large white primary patches.

Black-billed Magpies are known to be one of the few non-mammal species capable of recognizing themselves in a mirror. They are also famous for building large, domed nests made of sticks, sometimes with two entrances.

Good condition. There are minor separations in the distal barbs (nicks), likely from natural wear or handling, but no significant parasitic damage or fault bars are visible.
