LIST OF BIRDS OF CHEYENNE AND VICINITY. 



BY FKANK BOND. 



Cheyenne is located in the midst of the Great Plains region, a 

 little over 6000 feet above the ocean, with an annual rainfall of 

 thirteen inches. The plains around Cheyenne are drained by streams 

 fringed by cottonwoods and willows which attract the migrants. 

 One of these streams flows through the city, which by persistent 

 arboriculture has been made an immense grove of trees, an oasis in 

 the desert. Five small lakes, from within the city limits to a mile 

 and a hftlf beyond, offer resting places to waterfowl of all descrip- 

 tions. The mountain range twenty miles west of the city, acting 

 as a barrier to flight, completes the conditions which give Cheyenne 

 a peculiar and diversified avifauna. The list covers a radius of about 

 three miles from the city limits 



sEchmophorus occidentals: Western Grebe. Rare visitant. 



Colymbus holbodlii : Holbcell Grebe. Rare visitant. 



Colymbus nigricollis calif ornicus : Eared Grebe. Common during' migra- 

 tions. 



Gavia imber : Loon. Not common but tolerably regular visitor during 

 migrations.
