Nesting of the Arctic Three-toed Woodpecker in the Adirondacks Hv LAURENCE ACHILLES A I' i luce thousand feel or more above the sea, m the denser spruce :ind balsam forests of the Adirondacks, the Arc lie Three-toed Wood pecker is fairly common. Two broods of young were found flyinjj; about on June 2s> though the nesf of which I speak was nol deserted until J nly s or 6. The young birds betrayed their whereabouts by incessantly crying for lood. The nest was discovered on June- 22, but it was nol visited again till ten days later, — July ■{. It was located on the summit ol Kartlctt Ridge, in Essex county, New York, at an altitude of three thousand seven hundred feel. The trees near the nest were chiefly spruces, with a few balsams and birches scattered among them. The birds had selected a rather open place for their nesting-site, as, within a radius of ten yards from (heir nest, there were several windfalls and dead spruces. The ground was carpeted with moss, while linnea, clintonia, wood -sorrel and bunchberry were blossoming in profusion near the base of the tree. The hole, which was in a spruce tree, laced north by nort beast, and was twenty seven feet one inch from the ground. The spruce retained all its branches and some lwijj;s, although it had been dead for some time. The following dimensions of the hole were taken alter the young had 'eft their nest. The entrance to the hole was two inches wide ami one and five eighths inches high. From the outside of the hole, straight through OVd the (op of the nest to the back of the hole, (he measurement was five and three fourths inches. The outside shell, including the bark, was one and three-fourths inches thick. Idie diameter of the nest opening was three and one fourth inches, while the diameter of the- hole on the inside- at the bottom ol the- shad , was four and five-eighths inches. The depth of the hole- was nine and one eighth inches.

The female seemed much more- concerned about the- welfare of her -young than her mate-. Before lighting near the- hob- to teed them, she would fly around in the vicinity ol the nest, uttering guttural notes somewhat resembling the syllable "wick." The old bird's notes were- not so sharp as those of the Many Woodpecker, but more guttural. Several limes when the female was getting grubs in the- dead spruce near the hole-, the male would fly from some distant tree and alight near her. She would see him coming and, just as he was about to alight, would (158)
