Major Bendire (1895) says: I obtained my first set of eggs of this species on June 3, 1883, about 9 miles north of Fort Klamath, in the open pine forest on the road to Crater Lake. It consisted of five eggs, slightly incubated. The nesting site was excavated in a partly decayed pine whose entire top for some 20 feet was dead; the height of the excavation from the ground was about 50 feet. The man climbing the tree reported it to be about 8 inches deep and about 5 inches wide at the bottom, and freshly made. A second set, of six fresh eggs, was taken June 12 of the same year, about 12 miles north of the Post, at a still higher altitude than the first one. It came also out of a pine about 40 feet from the ground. A third nest, found a week later, near the same place, contained five young, just hatched. This nest was in a dead aspen, about 20 feet from the ground. Only one brood is raised, and, like the other two species, it is only a summer resident in the vicinity of Fort Klamath. Other observers have found nests in lodgepole pines, red firs, and larches at various heights from 5 to 60 feet above ground but always in conifer associations. _Eggs._--Bendire (1895) says: “The number of eggs laid to a set varies from three to seven, sets of five or six being most often found. These, like all woodpecker’s eggs, are pure china-white in color; the shell is close grained, rather thin, and only slightly glossy. In shape they vary from ovate to elongate ovate, and a few approach an ovate pyriform, a shape apparently not found in the eggs of other species of this genus.” The measurements of 30 eggs average 23.54 by 17.23 millimeters; the eggs showing the four extremes measure =25.91= by 17.27, 24.1 by =18.3=, and =20.1= by =15.4= millimeters. _Young._--Both parents assist in the duties of incubation, but the length of time required for this function does not seem to be definitely known; both sexes also help in feeding the young. Dr. J. C. Merrill (1888) says, of two nests that he watched for some time: “The males brought food about twice as often as did the females, and frequently removed the excrement of the young on leaving the nest, alighting on the nearest tree for a moment to drop it and to clean their bills; I did not see either of the females remove any excreta. About four feet above one of the holes was another occupied by a pair of pigmy nuthatches, but neither species paid any attention to the other when they happened to arrive with food at the same time.”
