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 flies 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.

Sp. Ch — Mule. —Crest brownish black, composed of six feathers. Front grayish white, each feather having in its centre a 
longitudinal line of black. A transverse band of white, dividing the top of the head in about two equal portions, runs down the 
side of the neck, forming a border to the patch of chestnut covering the top and back of the head; a fine line of black lies 
between this white line and the chestnut patch. Throat black, encircled by a white band reaching nearly to the eye Upper 
parts and breast grayish slate, the feathers of the sides and back of the neck having in their centres a delicate longitudinal brown 
line. Primaries pale ashy brown, inner vanes of tertiaries bordered with cream color. Middle of breast and abdomen cream 
color, with a large black spot in the centre of the latter. Sides and flanks deep chestnut, each feather with a longitudinal linear 
spot of white. Under tail coverts with broad bands of ashy brown running down the centre of the feathers. Bill dusky. Feet

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