Hairy Woodpecker 225 



(Aiken) ; Twin Lakes, breeding (Scott) Wet Mountains to 10,000 feet 

 (Lowe) ; Breckenridge, breeding (Carter), Mesa co., common (Rock- 

 well) ; San Juan co., breeding up to timber line (Drew). 



Habits. — In the winter Hairy Woodpeckers can often 

 be met with among the cotton- woods and undergrowth 

 along the streams of the foothills, but in summer they 

 are mostly in the pine woods and aspens higher up. 

 They are active and industrious, hammering among 

 the tree trunks, searching for wood-borers and other 

 insects, while in the winter they devour a few berries 

 as well. Aiken took a nest near Fountain in El Paso 

 CO., on May 26th ; it contained four eggs. Gale also 

 found a great many nests about Gold Hill in Boulder co. 

 They were nearly all located in aspen trees, from 

 three to twenty feet up. 



The nest-hole is excavated by the bird itself in most 

 cases, though not infrequently a Sap-sucker's is appro- 

 priated. Tough-wooded trees are seldom chosen, and 

 the same site is often occupied for successive years. 

 The eggs, usually four or five in number, are white and 

 measure '98 x "73. Gale found fresh eggs from May 

 oth to June.

Description. — Closely resembling D, v. monticola, but smaller ; wing 

 about 4-8 ; tail 3-25 ; and the wing-coverts and inner secondaries 

 profusely white-spotted. 



Distribution. — Middle portion of the eastern United States from the 

 Atlantic to eastern Colorado. 



Anthony mentions a Colorado example of the typical eastern race 

 of the Hairy Woodpecker, and Smith took a pair, June Oth, 1906, on 

 Boye's Ranch, Dry Willow Creek, Yuma co. An example in the 

 Aiken collection from Dellvale, Norton co., Kansas, is typical of 

 the eastern form.
