304 Richmond and Knowlton oh Montana Birds. T Oct 



42. Stellula calliope. Calliope Hummingbird. — Two individuals 

 were noted, one of which, an immature bird, was obtained August 12, at 

 Bear Creek. 



43. Tyrannus tyrannus. Kingbird. — Common. 



44. Sayornis saya. Say's Phcebe. — Two specimens secured, and these 

 were the only ones seen. 



45. Contopus borealis. Olive-sided Flycatcher. — One shot on 

 Traill Creek, July 28. 



46. Contopus richardsonii. Western Wood Pewee. — Taken on 

 Spanisli Creek about the middle of August. 



47. Empidonax minimus. Least Flycatcher. — One specimen 

 secured on Bear Creek, August 13; this is an adult female, and is clearly 

 referable to the above species. 



4S. Empidonax hammondi. Hammond's Flycatcher. — Three 



immature birds were secured on Squaw Creek, August 19-20. 



49. Empidonax wrightii. Wright's Flycatcher. — Quite common ; 

 found usually in wooded ravines in the foothills. Fully fledged young 

 birds were found throughout the month of August. 



50. Otocoris alpestris arenicola. Desert Horned Lark. — Very 

 abundant everywhere in the valleys and on the foothills. Many young 

 in the nestling plumage were found during August. The old birds at this 

 time were in worn and faded plumage, and moulting. About September 

 20 large numbers of Horned Larks began to arrive from the north, and we 

 noted hundreds of them daily. Over sixty specimens were preserved, 

 and all of them are referable to the subspecies arenicola, although a few, 

 obtained from the ranks of the migratory flocks arriving late in Sep- 

 tember, approach O. a. merrilli 'in the possession of a yellowish edging 

 to the black crescent on the breast. The subspecies leucol&ma had 

 apparently not arrived by the first of October, at which time our obser- 

 vations ceased, but we have received numbers of this form from the 

 vicinity of Bozeman in midwinter. 



51. Pica pica hudsonica. American Magpie. — Very abundant, but 

 shy. Most numerous in the valleys, but noted also in the mountains. 

 Several seen at Mystic Lake. 



52. Cyanocitta stelleri annectens. Black-headed Jay. — Only occa- 

 sionally seen in the mountains. Three were seen near the upper end of 

 Gallatin Basin, at an altitude of about 9000 feet. Adults and young 

 secured. 



53. Perisoreus canadensis capitalis. Rocky Mountain Jay. — Very 

 common in the mountains from the lowest limit of the coniferous forests 

 up to at least 9000 feet, above which altitude we did not have occasion to 

 go. These birds were known locally by a varietj' of names, such as 

 Meatbird, Meathawk, Campbird, Camprobber, and by others who had 

 known the bird in Colorado, they were called Baldhead, Tallowhead and 

 Whitehead. Immature birds with traces of the dark first plumage were 

 found at Mystic Lake July 27.
