III. Notes on Birds observed in the vicinity of Elko, Nevada, be- 

 tween Aug. 9th and l^th, 1872. 



Elko is situated on the Humboldt River, and with the exception of 

 the bushes along the river is surrounded by the sage brush plains. 

 The river has many small grassy sloughs extending into the meadows 

 which border its banks at many places. Away from the river there 

 were many small sloughs in the meadows, sometimes partially enclosed 

 with bushes, affording shelter to many species which we were unable 

 to procure, owing to the shortness of our stay. From here we made 

 a short excursion twenty-five miles north. The locality visited was 

 a canon with a small stream flowing through, each bank of which 

 was covered with grass and bushes in scattered bunches. This 

 stream was the only water within several miles, making it a favorite 

 haunt of the birds of the locality. 



As I was indisposed during the day we spent there, probably many 

 common species were overlooked. For the purpose of comparing 

 the two localities I place the birds observed at Elko under Section A, 

 and those observed in the mountains under Section B.
