Range. - Western United States from southern California to southern British Columbia.
This odd species is wholly a dull black color, except for the white head and neck, and basal half of the primaries. They are quite abundant in some localities, particularly in California on mountain ranges. They nest at any height, but the greater number have been found under twenty feet from the ground and in old pine stubs. They lay from four to six glossy white eggs, measuring .95 x .70. They are said to be more silent than others of the Woodpecker family, and rarely make the familiar tapping and never drum. It is claimed that they get at their food by scaling bark off the trees, instead of by boring.

White.
