Notes on Bikds observed in portions of Utah, Nevada, 

 and California. By E. W. Nelson. 



The following notes were taken during the summer and fall of 

 1872. Although some of the localities have been quite thoroughly 

 worked up by different naturalists, yet I hope that the lists and notes 

 will add to the knowledge of the distribution and habits of many of 

 the species. The lists are not intended to form a complete catalogue 

 of the birds of any of the localities. At Nevada, Cal., owing to the 

 season of the year spent there, only a portion of the summer resi- 

 dents were obtained. The list, however, probably contains a majority 

 of the autumn visitants, with a few summer residents. For several 

 of the species and notes I am indebted to my companion, Mr. W. W. 

 Wentworth. Mr. Drexler's list of the Birds of Ft. Bridger, in the 

 Pacific R. R. Reports, Vol. ix, together with mine, will probably in- 

 clude nearly all the birds to be found at that locality. 



I. Notes on Birds observed in the vicinity of Fort Bridger, Utah, be- 

 tween June 22d and July 2^th, 1872. 



Fort Bridger is situated on the Black Fork of the Green River. 

 The stream is bordered by willows and cottonwoods with occasionally 

 a orassy meadow. Beyond these are the sage bush plains. Thirty 

 miles south of the Fort is a range of mountains covered with a heavy 

 growth of pine. Through the kindness of Mr. Carter, who was 

 runnino- several saw-mills there, I was enabled to spend a few days 

 collecting in these mountains. As there is quite a difference in the 

 species observed there and at the Fort, I have placed the notes on 

 those observed in the immediate vicinity of the Fort under Section 

 A, and those observed in the mountains under Section B. Along the 

 lower border of the pine forest were scattered clumps of cottonwoods 

 which were frequented by several species not found in the dense pine 

 forest higher up. 



A. Vicinity of Fort Bridger. 



turdim:. 



1. Tardus migratorius Linn. Robin. Abundant. Found 

 nests containing eggs the last of June. They were built in the wil- 

 lows, often on the very edge of the water. 



2. Turdus Swainsoni Cab. Olive-backed Thrush. Common. 

 Frequented the dense bushes along the creek, but were so shy tha 

 although often seen they were difficult to shoot.
