Thie woodpeokar was fairly oomoon on the high mesa of the Chuaoa Uountalns 
at 6800 and 9000 feet where it was found among the Yellow Pines and ijuaicing 
Aspens. It was ohsorred daily ditring worJc here. On July Z two nests containing 
well-grown young were observed In Cottonwood I^us. Both were placed in dead 
aspens and were about thirty feet from the ground. ?he ddalt bii'ds were very 
wary and would not oome near while X was in the nei^borhood. 
21. Plooides amerioanus dorsalis Baird. 
Alpine Three-toed Woodpecker. 
Tlxis species was fairly ootnuon among the Yellow-pines and Bouglau Firs 
on the high mesa of the Chusoa Uoimtains and was evidently breeding. On 
June 70 a male was found resting on dead limbs in the Yellow Pines and drum- 
ming at Intervals. The drum resembled taqnir ; taupr taney tanoy tr-r-r-r-r . 
being made up of four double notes and then a short roll. In a way it was 
like that of the Williamson's supsuoker given in reverse order. The bird fre- 
quently varied the tone by changing position on his sounding board. Others 
were observed feeding among the yellow pines on July 2. All worked eteddily a- 
way hammering at the tree trunks with strong, vigorous steady strokes like 
those of the hairy Woodpecker. 1 saw many signs of their work on the tree- 
trunks through here. They drill strai^t deep holeuiu bark and dead tree trunks 
sinking them in as though with a chisel.. The birds themselves looked much 
like rather email, somewhat dull colored Hairy Woodpeckers and had many of the 
mannerisms of that bird. All were silent save for thoir tapping. (iipooimens)
