The New International Encyclopædia/Oregon Snowbird

OREGON SNOWBIRD. A junco (Junco Oregonus) common in the Northwestern United States and Canada. It differs from the common Eastern junco (q.v.) in the blacker and more sharply defined hue of the head and neck, the absence of dark color under the wings, and the square patch of rufous brown on the upper part of the back. As in other juncos, white feathers appear in the tail. The male of this species has the second tail feather mostly white and the third partly so near the tip. The adult female's plumage differs from that of the male in being prevailingly brown.
