Yellow-billed Magpie

The Yellow-billed Magpie is a striking, highly social bird known for its extraordinarily long tail, contrasting black-and-white plumage, and brilliant yellow bill and eye-ring. It is one of the few bird species endemic to the state of California.

Stunning structural iridescence showing deep metallic blue and greenish-black gloss along the pennaceous vanes, terminating in a distinct, crisp white tip at the distal end

Tightly interlocked pennaceous structure along the main vane with firm barbules and hooklets, and a small plumulaceous tuft at the base

Smooth, glossy, and firm texture with high structural rigidity and a reflective, metallic surface finish

Striking metallic blue-black structural coloration contrasted sharply by a distinct white tip, combined with the elongated, tapered shape of a corvid tail feather

Oak savannas, agricultural fields, open grasslands, and riparian woodlands with scattered tall trees for nesting and roosting

Endemic exclusively to California, primarily inhabiting the Central Valley and surrounding foothills

Acts as an important scavenger, seed disperser, and insect predator in oak savanna ecosystems, helping control agricultural pest populations

Black-billed Magpie (Pica hudsonia), whose feathers are nearly identical in structure and pattern but belong to a more widespread northern species; separated primarily by geographic provenance

Yellow-billed Magpies are known to be highly susceptible to West Nile virus, which caused massive population declines in the early 2000s. They build large, domed stick nests that are often reused or commandeered by other species.

Good overall condition with minor wear and slight fraying at the extreme base near the calamus, but vanes and structural coloration remain vibrant and largely intact
