May 22, 1921, I made my way through four feet of snow to the same tree. A new nest had been made, and the female flew off when I was about 150 feet away. I cut into the nest and found a set of four eggs on which incubation had just commenced. The altitude at this point is 11,000 feet. May 26, 1922, I found a nest with young about seventy-five feet up in an aspen. This was in Santa Fe Canyon at an altitude of 8,000 feet. _Eggs._--The eggs of the Rocky Mountain hairy woodpecker are similar to the eggs of other hairy woodpeckers of similar size. The measurements of 33 eggs average 24.89 by 18.49 millimeters; the eggs showing the four extremes measure =28.08= by 18.03, 27.0 by =20.1=, =23.37= by 17.78, and 24.38 by =17.27= millimeters. _Food._--Mr. Skinner says, in his notes, that this woodpecker “seeks its food on the trunks of lodgepole and _flexilis_ pines, cedars, firs, aspens, willows, and even electric-light and telephone poles; it prefers dead and diseased trees and stubs to work on, probably because of more borers and grubs. At Basin, and over 7,000 feet elevation, I found a female where I could watch her, only 5 feet away from the lodgepole trunk on which she was working. She worked down, tapping here and there as she went. Whenever a tap revealed a borer, she scaled off the bark with quick right and left strokes, having a slight lever motion at the end, and always secured from one to six bark-borer grubs. Evidently the tap told her whether it was worth while to search further, for she never made a mistake and performed no useless labor.” J. A. Munro (1930) writes: “During the winter of 1928-29 a male hairy woodpecker frequently was seen feeding on Virginia creeper berries in competition with several red-shafted flickers. On one occasion the same bird visited an apple tree, attracted by a few apples that still clung to the bare branches. Standing crossways on a branch, in the ordinary position of a perching bird, he rapidly stabbed his bill downward into the top of an apple. After doing this several times he flew to another portion of the tree and repeated the performance.” DRYOBATES VILLOSUS PICOIDEUS Osgood QUEEN CHARLOTTE WOODPECKER HABITS Dr. Wilfred H. Osgood (1901) described the hairy woodpecker of the Queen Charlotte Islands, as a full species, _Dryobates picoideus_. He says it can be distinguished from all other members of the _villosus_ group by the black markings on the back and characterizes it as “similar in general to _Dryobates v. harrisi_; bill slightly smaller; middle of back barred and spotted with black; flanks streaked with black.” He says that this woodpecker is not abundant on the islands; during a period of over a month spent in active collecting he saw only six, all of which were collected.
