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 
5th to June.

A.O.U. Checklist no 393—Colorado Records—Anthony 96, p. 32; 
H, G. Smith 08, p. 185. 
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 9th, 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.
