REPORT UPON ORNITHOLOGICAL SPECIMENS. 



Ill 



throughout the rolling plains along the bases of the mountains, and 

 even quite high up among the foot-hills. It was usually associated with 

 the Savanna and Yellow-winged Sparrows, and seems to embrace in its 

 habits certain characteristics of either species. Its flight is particularly 

 like that of the former bird, but even more wild and irregular. It pur- 

 sues its zigzag course for a couple of hundred yards, and then, suddenly 

 turning sharply to one side, alights behind some friendly bush or tuft of 

 grass. Like the Yellow-winged Sparrow, it is difficult to flush, but seeks 

 rather to evade search by running nimbly through the grass, changing 

 its course frequently, and hiding wherever possible, flying only when 

 hard pressed. A large number of specimens were secured, all molting, 

 and many in extremely ragged plumage. From their condition, it is 

 presumed that they were not migrants, but breed in the immediate 

 locality. The following measurements, taken from fresh specimens, 

 were selected from a series of over thirty : 



GO. Passerculus savanna (Wil.), var. alaudinus, Bp. Western Savanna 

 Sparrow. 



During the fall often found on the high dry plateaus. Always nu- 

 merous in the vicinity of sloughs and streams. 



Gl. Pooccetes 

 Finch.
