On May 10, 1883, while en route from Fort Klamath to Linkville, Oregon, and only a few miles from the latter place, just where the pine timber ended and the sagebrush commenced, I found a male busily at work on a pine stump, only about 2½ feet high and about 18 inches in diameter, standing within a few feet of the road, and close to a charcoal burner’s camp, in quite an open and exposed situation, nearly all the timber in the vicinity having been cut down. The stump was solid, full of pitch, and showed no signs of decay; the entrance hole was about 1½ inches in diameter and 8 inches from the top. The cavity, when first examined, was only about 2 inches deep, and on my return, two days later, it had reached a depth of 4 inches: the female was then at work. To make sure of a full set of eggs, I waited until the 25th. The cavity then was found to be 18 inches deep, and was gradually enlarged toward the bottom. The four eggs it contained had been incubated about four days. The female was on the nest, and uttered a hissing sound as she left it, and might easily have been caught, as she remained in the hole until the stump was struck with a hatchet. The sides of the cavity were quite smooth, and the eggs were partly embedded in a slight layer of pine chips. The locality where this nest was found was near the top of a low divide, not over 4,100 feet in altitude. Dr. Thomas S. Roberts (1932) calls attention to an interesting feature in the nesting habits of this woodpecker, as observed in two nestings that he saw in Minnesota; he says of the two nests: The nesting-hole was in a live jack-pine on the edge of a tamarack and spruce swamp, only twenty feet from a traveled road and close by a log house used as a store. The entrance faced south and was twelve feet from the ground, at which point the tree was seven inches in diameter. The outer bark of the tree had been chipped off for a distance of twelve to fifteen inches above and below the hole and half-way around the tree, thus leaving a large, irregular, whitish area. * * * Another nest, found the same season, was also in a live evergreen tree and the outer bark had been similarly stripped from around the entrance, making a conspicuous, white patch with the dark nesting-hole in the center. Can this be a direction mark for the returning bird among the dark tree trunks around? As to the height from the ground, P. B. Philipp writes to me that of 26 nesting holes examined by him in New Brunswick two were 15 feet, two 12 feet, three 10 feet, one 8 feet, two 6 feet, two 5 feet, four 4 feet, six 3 feet, and four only 2 feet above ground.
