PARUS ATRICAIPILLUS PRACTICUS Oberholscr 

 APPALACHIAN CHICKADEE 



This form of black-capped chickadee, which is supposed to range from 

 eastern Ohio to southwestern Pennsylvania and southward through the 

 mountain region to North Carolina, is described by Dr. H. C. Ober- 

 holser (1937) as "similar to Penthestes atricapillus atricapillus, of 

 Canada, but smaller, particularly the tail ; upper parts darker, more 

 grayish, less ochraceous, particularly in winter ; wing-coverts and rec- 

 trices with narrower white edgings." Dr. Oberholser gives the range 

 as: "Resident and breeds chiefly in the Appalachian Mountains from 

 southwestern North Carolina, north through western Virginia, West 

 Virginia, southwestern Pennsylvania, to central eastern and northeast 

 central Ohio." Presumably the habits do not differ from those of the 

 typical race.

 brownish above, and darker buff on flanks and under tail-coverts. 

 White edgings to wing and tail feathers narrower. Bill larger. In 

 color nearer to P. a. occidentalis than to any other known race but
