727c. ROCKY MOUNTAIN NUTHATCH. Sitta caolinensis nelsoni. 



A common resident throughout this region, inhabiting the wooded 

 districts of the foothills and the mountainous localities, and also occurring 

 less commonly among the groves of deciduous trees in the vicinity of the 

 water-courses. 



Distinguishing features: Upper parts bluish gray, top of head black, 

 sides of neck white, wings varied with black; under parts white; length 5-6 

 inches. 



728. RED-BREASTED NUTHATCH. Sitta canadensis. 



Not uncommon in the wooded foothills and mountains. Messrs. 

 Richmond and Knowlton took specimens at low elevations in September in 

 south-central Montana. 



Distinguishing features: Upper parts bluish gray, top and sides of 

 head black; white stripe above eye; under parts light rusty red; length 

 4-5 inches. 



730. PYGMY NUTHATCH. Sitta pygmaea. 



Dr. J. G. Cooper, in "The Fauna of Montana Territory," says that 

 flocks of this little bird were met with at intervals from the eastern 

 base of the Rocky Mountains, in August, frequenting the open woods of 

 pine, and were more gregarious, lively, and noisy than the other nut- 

 hatches, constantly chirping like young chickens, and like them seeking 

 insects more among the leaves than in the bark. 



Distinguishing features: Upper parts dull bluish gray, top of head 

 brown; lower parts dull white; length about 4 inches. 

 735a. LONG-TAILED CHICKADEE. Parus atricapillus septentrionalis. 



A common resident of the timber and bushy tracts along the water- 

 courses, and also occurring everywhere in the wooded foothills and moun- 

 tains. 



Distinguishing features: Upper parts ash-gray, wings varied with 

 white; lower parts dingy white, with a faint yellowish tinge; top of head 

 black; length 5-6 inches. 



738. MOUNTAIN CHICKADEE. Parus gambeli. 



A regular resident of the wooded foothills and mountains, though 

 less common than the other chickadee in lower altitudes. 



Distinguishing features: Much like the long-tailed chickadee, but 

 easily known by the white stripe above the eye. The wing-coverts also 

 lack the whitish edgings which are noticeable in the other species. 



748. GOLDEN-CROWNED KINGLET. Regulus satrapa. 

 Occurs regularly in summer throughout the mountains of this region. 

 Distinguishing features: Upper parts grayish-olive, wing-coverts with 



whitish edges; crown with a patch of orange-red, bordered by yellow with- 

 in black; lower parts dull white; length about 4 inches. 



749. RUBY-CROWNED KINGLET. Regulus calendula. 



Found regularly in the mountainous districts of this region. In the 

 summer of 1903, I found the ruby-crowned kinglet nesting in the Flathead 

 Lake region. A nest was taken on July 6, which was situated in a fir tree 

 beside a road through the woods. The nest was near the extremity of a
