I can find nothing noted on its habits that is in any way different from those of the other eastern races. So far as I know, its eggs have never been taken. DRYOBATES VILLOSUS ICASTUS Oberholser CHIHUAHUA WOODPECKER PLATE 6 HABITS The hairy woodpeckers of the Canadian and Transition Zones in the mountains of northwestern Mexico, southern Arizona, and southern New Mexico are referable to this race. In describing and naming it, Dr. H. C. Oberholser (1911a) characterized it as “similar to _Dryobates villosus hyloscopus_, but bill much smaller, and wing slightly longer. * * * This bird is decidedly smaller than _Dryobates villosus leucothorectis_, as well as noticeably smoky-tinged on the under surface, instead of pure white; and it is in size so very much inferior to _Dryobates villosus orius_, that it is readily distinguishable.” Harry S. Swarth (1904) says of the haunts of this woodpecker in the Huachuca Mountains, Arizona: “Fairly abundant in the higher parts of the mountains, from 7,000 feet upward. They may be seen almost anywhere in that region, but for breeding purposes, seem to particularly favor the dense thickets of quaking asp.” In 1922, Frank C. Willard and I found them breeding mainly among the tall pines near the summit of these mountains, above 7,500 feet. From here to the summit, about 9,000 feet, the land is rolling, mostly in gentle slopes, and covered with a fine, open, parklike forest of tall pines of two or three species, many of them from 80 to 100 feet high. The many dead, standing trees and stumps offered suitable nesting sites for pygmy nuthatches, Mexican creepers, and Chihuahua woodpeckers. We did not see any of these woodpeckers in the spruce and fir belt, below 7,000 feet.
