white, marked or bridled with black; back olive 
gray ; under parts dingy whitish. Young: simi¬ 
lar, but throat gray, except for black on chin ; 
head markings less defined. Length: 4.50-5.00,

tonwood down, ferns, grasses, and cotton waste. 
Eggs : 5 to 7, plain white. 
The oddly marked little wollweberi is an 
eminently social bird, Mr. Henshaw tells us, 
going about, except in the nesting season, in 
flocks of twenty-five or more. It hunts for food largely in oaks, 
passing along more quietly than other titmice. 
Subgenus Parus. 
Not crested. 
735. Parus atricapillus Linn. Chickadee. 
Adults. — Top of head and throat black; back ashy or olive grayish, 
sometimes tinged with buffy; sides buffy; rest of under 
parts white. Young: upper parts dark slate; under parts 
salmon color, faintest on breast. Length: 4.70-5.75, wing 
2.55- 2.75, tail 2.50-2.70. 
Distribution. — Breeds in eastern North America north of 
the Potomac and Ohio valleys and west to western Nebraska. Fi ®- 584, 
Recorded from Fort Sherman, Idaho. 
Nest. — In holes in trees or stumps, made of moss, fur, hair, and some¬ 
times feathers. Eggs: 4 to 8, white, spotted with reddish brown and lilac, 
chiefly around larger end. 
Food. — Injurious insects and their eggs, including tent-caterpillars, 
cankerworms, and plant lice ; also seeds and small fruit. 
At Fort Sherman, Idaho, the chickadee appears, strangely enough, 
to be practically identical with the far removed eastern black- 
capped.
