Pica hudsonia (Black-billed Magpie)

Synonyms: Corvus hudsonia (homotypic); Pica pica hudsonia

Wikipedia Abstract

The black-billed magpie (Pica hudsonia), also known as the American magpie, is a bird in the crow family that inhabits the western half of North America, from southern coastal Alaska to northern California, northern Nevada, northern Arizona, northern New Mexico, central Kansas, and Nebraska. It is black and white, with black areas on the wings and tail showing iridescent hints of blue or blue-green. It is one of only four North American songbirds whose tail makes up half or more of the total body length (the others being the yellow-billed magpie, the scissor-tailed flycatcher, and the fork-tailed flycatcher).
