BIKDS. 19 



This bird was first observed in numbers on the Pecos river, although seen some days previous 

 to reaching this point. Its numbers increased as we neared civilization, and near San Antonio it 

 became plentiful. The call of the male bird consists of two notes, (repeated at intervals,) which 

 are less loud, clear, and ringing than those of our common quail, (0. virginianus.) It feeds 

 on the open prairies upon grass seeds, grains, berries, and insects, and if alarmed takes refuge 

 among the scattered mesquite trees and clumps of bushes. When hunted it lays to the dog like 

 our common species, and if flushed flics in a direct line with a loud whirring noise, caused by 

 the shortness and rapid motion of the wings. I found an egg of this bird, which had been 

 dropped upon the road. In form and color it was like that of our common quail though smaller.

From Fort Yuma, on the Colorado, to Eagle Springs, between El Paso and San Antonio, 

 ■where we last saw a flock of these birds, we found them more or less abundant whenever we 

 followed the course of the Gila or struck water holes or streams of any kind. Although 

 frequenting the most arid portions of the country, where they find but a scanty subsistence of 

 grass seeds, mesquite beans, and insects, still they show a preference for the habitation of man, 

 being much more numerous in the cultivated fields of Tucson, Mesilla valley, and El Paso. 

 Towards evening, in the vicinity of the Mexican villages, the loud call note of the male bird is 

 heard, gathering the scattered members of the flock, previous to issuing from the cover where 

 they have been concealed during the day. Resorting to the trails and roads in search of sub- 

 sistence, they utter while thus engaged a low soft note which keeps the flock together. They 

 are not of a wild nature, often permitting a near approach, and seldom fly unless suddenly 

 flushed, but prefer to escape from danger by retreating to the dense thickets.
