Mr. John K. Lord states that the only place in which he saw this very rare bird was in the open timbered country about the Colville Valley and Spokan River. He has observed that this Woodpecker almost invariably haunts woods of the Pinus ponderosa, and never retires into the thick damp forest. It arrives in small numbers at Colville, in April, and disappears again in October and November, or as soon as the snow begins to fall. Although he did not succeed in obtaining its eggs, he saw a pair nesting in the month of May in a hole bored in the branch of a very tall pine-tree. It seldom flies far, but darts from tree to tree with a short jerking flight, and always, while flying, utters a sharp, clear, chirping cry. Mr. Ridgway found it to be common in the pine forests of the Sierra Nevada, in the region of the Donner Lake Pass. It was first observed in July, at an altitude of about five thousand feet, on the western slope of that range, where it was seen playing about the tops of the tallest dead pines. On various occasions, at all seasons, it was afterwards found to be quite plentiful on the eastern slope, in the neighborhood of Carson City, Nevada. Its habits and manners are described as much like those of the P. harrisi, but it is of a livelier and more restless disposition. Its notes have some resemblance to those of that species, but are of a more rattling character. It is easily recognized, when seen, by its strikingly peculiar plumage.

39143 ♂
Gen. Char. Bill about as long as the head, very much depressed at the base; the outlines nearly straight; the lateral ridge at its base much nearer the commissure than the culmen, so as to bring the large, rather linear nostrils close to the edge of the commissure. The gonys very long, equal to the distance from the nostrils to the tip of the bill. Feet with only three toes, the first or inner hinder one being wanting; the outer lateral a little longer than the inner, but slightly exceeded by the hind toe, which is about equal to the tarsus. Wings very long, reaching beyond the middle of the tail, the tip of the first quill between those of sixth and seventh. Color black above, with a broad patch of yellow on the crown; white beneath, transversely banded on the sides. Quills, but not wing-coverts, with round spots. Lateral tail-feathers white, without bands on exposed portion, except in European specimens.
The peculiarities of this genus consist in the absence of the inner hind toe and the great depression of the bill. The figure above fails to represent the median ridge of the bill as viewed from above.
Common Characters. The American species of Picoides agree in being black above and white beneath; the crown with a square yellow patch in the male; a white stripe behind the eye, and another from the loral region beneath the eye; the quills (but not the coverts) spotted with white; the sides banded transversely with black. The diagnostic characters (including the European species) are as follows:—
