36 Saunders, Birds of Gallatin Co., Moid. |_jan. 



*59. Astur atricapillus. Goshawk. — Rare summer resident in the 

 mountains where Mr. Ginn, a taxidermist in Bozeman, found a nest on 

 Spanish Creek. Common fall migrant and occasional throughout the 

 winter in both valleys and mountains. 



*60. Buteo borealis calurus. Western Red-tail. — Common sum- 

 mer resident, breeding in tall firs in the mountains and foothills. It 

 arrives about the first of April and leaves in the middle of October. 



61. Buteo swainsoni. Swainson's Hawk. — Summer resident in 

 the valleys, nesting in cottonwood groves. This species appears to be much 

 commoner at lower elevations in the northern part of the county. 



62. Archibuteo lagopus sancti-johannis. — Rough-legged Hawk. 

 — Common winter resident in the valleys. This is the only abundant 

 winter hawk. It appears about Oct. 10 and remains until the middle of 

 April. It feeds largely on gophers and will probably prove to be of value 

 for this reason. 



63. Archibuteo ferrugineous. Ferruginous Rough-leg. — Sum- 

 mer resident. Not common in the Gallatin Valley but common in the 

 Three Forks and East Flathead Valleys. Mr. Thomas found a nest in a 

 cottonwood grove near Three Forks in June, 1909. 



64. Aquila chrysaetos. Golden Eagle. — Permanent resident. 

 A few pairs breed in the West Gallatin Canon, and Mr. Thomas found a 

 nest of the species in Bridger Canon. 



65. Haliaeetus leucocephalus. Bald Eagle. — I saw a bird of this 

 species in Middle Creek Canon Nov. 10, 1908. Mr. Thomas reported 

 another which was captured alive on Maine St., Bozeman, in July, 1909. 



66. Falco mexicanus. Prairie Falcon. — Summer resident. I 

 have seen this species only at Three Forks but there is a specimen at the 

 Agricultural College which was found dead in the Gallatin Valley near 

 Bozeman. 



67. Falco peregrinus anatum. Duck Hawk. — Summer resident. 

 Fairly common from the middle of April until the last of October. Mr. 

 Rheesis Fransham showed me a nest of this species on a limestone cliff 

 on Squaw Creek, in the West Gallatin Canon. 



68. Falco columbarius richardsoni. Richardson's Pigeon Hawk. 

 — Taken on the Madison River by Richmond and Knowlton, Sept. 23, 

 1888. Mr. Thomas noted this species twice during the summer of 1909 

 in the mountain canons south of Bozeman. 



*69. Falco sparverius phalaena. Desert Sparrow Hawk. — Abun- 

 dant summer resident in the valleys and lower mountain canons. It ap- 

 pears in the latter part of April and leaves in October. 



70. Pandion haliaetus carolinensis. Osprey — I have seen this 

 species but once, June 13, 1909, near Bozeman. Richmond and Knowlton 

 recorded it as rather common and it is probably more abundant along 

 the larger rivers. 



71. Asio wilsonianus. Long-eared Owl. — Richmond and Knowl- 

 ton noted this species along the Jefferson River. Mr. Thomas saw some
