This woodpecker was fairly common on the high mesa of the Chusca Mountains at 8800 and 9000 feet where it was found among the Yellow Pines and Quaking Aspens. It was observed daily during work here. On July 3 two nests containing well-grown young were observed in Cottonwood Pass. Both were placed in dead aspens and were about thirty feet from the ground. The adult birds were very wary and would not come near while I was in the neighborhood.

21. Picoides americanus dorsalis Baird.

Alpine Three-toed Woodpecker.

This species was fairly common among the Yellow-pines and Douglas Firs on the high mesa of the Chusca Mountains and was evidently breeding. On June 30 a male was found resting on dead limbs in the Yellow Pines and drumming at intervals. The drum resembled [[underlined]] tappy tappy tappy tappy tr-r-r-r-r, [[/underlined]] being made up of four double notes and then a short roll. In a way it was like that of the Williamson's sapsucker given in reverse order. The bird frequently varied the tone by changing position on his sounding board. Others were observed feeding among the yellow pines on July 2. All worked steadily away hammering at the tree trunks with strong, vigorous steady strokes like those of the Hairy Woodpecker. I saw many signs of their work on the tree-trunks through here. They drill straight deep holesin bark and dead tree trunks sinking them in as though with a chisel.. The birds themselves looked much like rather small, somewhat dull colored Hairy Woodpeckers and had many of the mannerisms of that bird. All were silent save for their tapping. (Specimens)

22.- [[underlined]] Sphyrapicus varius nuchalis [[/underlined]] Baird.

Red-naped Sapsucker.

These birds were seen in Cottonwood Pass up to 8000 feet. On June 28 a pair were feeding well grown young in a hole drilled in a living quaking
