ANNOTATED LIST OF THE BIRDS OF FREMONT COUNTY 



37 



50. Pica pica hudsonia. Magpie. On June 5 and August 29 Magpies were noted 

 commonly in Montana along the Oregon Short Line, nearly to Monida, Fremont County. 

 I had expected to find them common in Fremont County, but not a single one was ob- 

 served during the summer. I was told that they had been common in former years, and 

 I found a number of old nests in willow thickets, near springs, but there were none of 

 recent make. 



51. Cyanocitta stelleri annectens. Black-headed Jay. Occurs sparingly in the 

 heavily wooded canyons throughout the county. 



52. Corvus brachyrhynchos hesperis. Western Crow. Not common. One seen 

 along Little Dry Creek, near Spencer, July 15, and three near Kilgore, August 26.

SHOWING DEEPLY CUPPED STRUCTURE. 



53. Nucifraga columbiana. Clarke Nutcracker. Occurs sparingly in heavily 

 wooded canyons throughout the county. A number of full grown young were seen in 

 Little Dry Creek Canyon, June 18. 



54. Molothrus ater ater. Cowbird. Two seen at a stock corral near Highbridge. 

 June 26. Cowbird eggs were found in the following nests: Brewer Blackbird, one, with 

 five eggs of the owner; White-crowned Sparrow, one, with a set of four; Sage Sparrow, 

 two, with one of owner. In the last mentioned instance I removed the two Cowbird eggs, 

 and the mother sparrow deserted her nest. 



55. Xanthocephalus xanthocephalus. Yellow-headed Blackbird. Two seen near 

 Kilgore, August 26, in company with a large flock of Redwings.
