In California Cabanis’ Woodpecker is common in the mountains, but in the lowlands in the southern part of this State Mr. F. Stephens considers it a rather rare summer resident. He found it breeding in a cottonwood tree, near San Bernardino, on March 21, 1885. Mr. Lyman Belding took several nests of this subspecies in Calaveras County, in the Sierra Nevadas; in one, found on June 6, 1879, which had been excavated in a dead pine stump, 12 feet from the ground, the eggs, three in number, were on the point of hatching. In his notes he says: “I scared the female from it and prevented her return by inserting a stick, the end of which protruded for several feet. When she found she could not enter she gave several cries, which brought the male, who hopped up and down the stick a few times, striking it with his bill and screaming angrily, pausing occasionally, and apparently deliberating on the best method of extracting it.” Another nest, found by him on July 10, 1880, was located only 3 feet from the ground, and contained young which were still in the nest on the 20th. Mr. Charles A. Allen informs me that along the Sacramento River, in California, it breeds in sycamores and willows, but that it is not common there. _Eggs._--Major Bendire (1895) says: The number of eggs laid to a set varies from three to six; those of four are by far the most common; sets of five are only occasionally met with, while sets of six are very unusual. * * * The eggs lie on the fine chips left in the bottom of the cavity, and are occasionally well packed into these, so that only about one-half of the egg is visible. They resemble the eggs of _Dryobates villosus_ in color, but those of an elliptical ovate shape are more common than the oval and elliptical ovals, averaging, therefore, more in length, while there is proportionally less difference in their short diameter. The measurements of 23 eggs average 24.49 by 18.38 millimeters; the eggs showing the four extremes measure =25.7= by 18.2, 24.2 by =19.7=, =22.8= by 18.1, and 24.9 by =16.5= millimeters. _Young._--Mrs. Irene G. Wheelock (1904) says: “Both sexes share the labors of excavating, brooding the eggs, and feeding the young. Incubation lasts about fifteen days, and the young remain nearly four weeks in the nest, being fed most of that time by regurgitation. After leaving they are fed by the parents for at least two weeks, and usually return to the nest at night to sleep.”
