In the western half of the county, an observer may consider himself fortunate to see an individual of this species twice a week. In the eastern portion, during July and August, along Transition zone streams, one or two birds may be seen nearly every day. We have obtained no definite nesting dates for this species, although it evidently breeds in suitable locations. On July 22, 1923, a brood of young on the wing was seen near Fortine in woods of spruce and aspen, in the Transition zone, at 2,960 feet altitude. Major Bendire (1895) writes: Dr. Edgar A. Mearns, United States Army, reports it breeding sparingly throughout the _Pinus ponderosa_ belt, ascending into the Spruce zone, on the San Francisco cone, and considers it the rarest of the woodpeckers found in Arizona. Mr. Denis Gale took a nest and eggs of this subspecies in Boulder County, Colorado, on June 12, 1889. The excavation was found in a half-dead aspen, 30 feet from the ground, and presumably well up in the mountains, as Mr. William G. Smith informs me that it is only a winter visitor in the lower valleys, and is never seen there during warm weather. I found it rare near Fort Custer, Montana, and only obtained a single male specimen, on November 23, 1884, among the willows and cottonwoods on the Little Horn River. Dr. James C. Merrill, United States Army, met with it breeding at Fort Shaw, Mont., early in June, 1879, and tells me that five or six eggs are generally laid to a set, and that the nesting habits are just like those of the downy woodpecker. Lee R. Dice (1918) says that, in southeastern Washington, it is “numerous throughout the year in the timber along the Touchet River near Prescott. “* * * On June 11, 1908, a nest containing young was found four feet from the ground in an apple tree near Prescott. The female was seen gathering large, red aphids from nearby golden-rod. She would gather all her mouth could hold and until the aphids stuck out like a fringe all around the edges of the bill. Then she flew in a direct line toward the nest. This female was also seen to gather aphids from apple trees.” A set of four eggs in the Thayer collection was taken near Fort Shaw, Mont., on June 8, 1879; the nesting cavity was 12 feet from the ground in a dead tree and was excavated to a depth of 10 inches. The eggs are characteristic of the species, short-ovate in shape, dull white in color, and only slightly glossy. The measurements of 28 eggs average 19.86 by 15.29 millimeters; the eggs showing the four extremes measure =23.37= by =16.00=, =19.0= by 14.8, and 18.4 by =14.4= millimeters.
