This familiar and active little bird is almost confined to the north- 

 ern half of the State, making its appearance south of the 89th 

 parallel, so far as the writer's knowledge and observation are con- 

 cerned, only at rare or at least very irregular intervals during the 

 coldest weather. Its habits are too well known to require descrip- 

 tion here.

Parus atricapillus var. carolinensis Coues, Key, 1872, 81; Cheek List, 1873, No. 316. 



HAB. Southern half of Eastern United States, north to or beyond 40, west to eastern 

 Texas and Indian Territory. (Resident throughout its range.) 



"Sp. CHAR. Second auill appreciably longer than secondaries. Tail very little rounded 

 Length about 4.50 inches; wing less than 250; tail, 2.40.* Back brownish ash. Head 

 above, and throat, black, separated on sides of head by white. Beneath white; brownish 

 white on sides. Outer tail feathers, primaries, and secondaries, not edged with white." 



This species, which is the more common one in Illinois (except 

 the extreme northern counties) may readily be distinguished from 

 P. atricapillus by the more extensive and more "solid" black on the , 

 throat ; by the absence of distinct white edgings to the wing and 

 tail feathers, and by the different proportionate length of the wing 

 and tail. (See synoptical table.) 



This pretty, active and familiar little bird occurs throughout the 

 State, but is most common in the southern half, where it is the 

 representative of the northern Black-cap (P. atricapillus}. The 



*In fourteen adults, the wing measures 2.40-2.60, the average being 2.46; tail 2.10-2.50 

 (average, i'.15); tarsus, .55-.6S (average, .60).
