PERCHING BIRDS 



735a. LONG-TAILED CHICKADEE. Penthestes 

 ataricapillus septentrionalis. 



Range. Rocky Mountain region, north to British Co 

 lumbia. 



This variety is very similar to the last but has a slightly 

 longer tail and the colors are purer. Its nesting habits 

 are the same and the eggs are indistinguishable from those 

 of the eastern Chickadee. 



735b. OREGON CHICKADEE. 

 occidentals. 



Penthestes atricapillus 



Range. Pacific coast from California to Alaska. 



The habits and eggs of this slightly darker variety are 

 just the same as those of the common Chickadee of 

 the east. 



786. CAROLINA CHICKADEE. 

 carolinensis. 



Penthestes carolinensis 



537538 



White 



Range. Southern United States from the 

 Gulf to New Jersey and Illinois. 



The southern Chickadee is smaller than 

 the northern and the wing coverts and feathers have little or 

 no white edgings, Their nesting habits are in every particular 

 the same as those of atricapillus and the eggs cannot be dis- 

 tinguished with certainty, but average smaller; size .53 x .43. 



736a. PLUMBEOUS CHICKADEE. Penthestes carolinensis agilis. 



Range. Eastern and central Texas. 



This variety is said to be more plumbeous above and much whiter below 

 than the preceding. No differences can be found in the eggs of the two varieties 

 and the nesting habits are the same. 



737. MEXICAN CHICKADEE. Penthestes sclateri. 



Range. Mountains of western Mexico north to southern Arizona. 



This species has the black more extended on the throat and the under parts 

 are grayish of a lighter shade than the upper, the cheeks, however, remaining 

 white. Their nests are in hollow stubs and the eggs are indistinguishable from 

 those of the foregoing Chickadees. 



738. MOUNTAIN CHICKADEE. Penthestes gambeli gambeli. 



Range. Rocky Mountain region and west to the Pacific; north to British 

 Columbia chiefly in higher ranges. 



This handsome little Titmouse has a white superciliary 

 line, leaving a black stripe through the eye. Their habits 

 are like those of the other Chickadees and they are equally 

 confiding and inquisitive. Their eggs range from five to eight ^v: : , ; 

 in number and are either pure white or faintly marked with 

 reddish brown; size .60 x .45. Data. Estes Park, Colorado, 

 June 8, 1803. Nest in an old Sapsucker's hole in a live as- \viiite
