Dr. E. Coues.— From Arizona to the Pacific. 
ping suddenly and, drawing itself up to its full height, watching 
the intruder with curious eye. Its voice is soft and low, and 
very peculiar in tone. The iris is dark brown, the legs and feet 
leaden-blue*. 
Among the Raptores here at San Pedro we find Archihuteo 
ferrugineus very common. It alights freely on the ground, 
where I often observed it. At Fort Whipple, where it was 
abundant, I never saw it except upon trees; and here it may be 
making a virtue of necessity in thus choosing the bare plain. 
Falco nigriceps and F. polyagrus are more uncommon. I shot 
a specimen of the latter off the roof of my house; it had the 
eyes brown, bill horn-blue, feet and legs light leaden-blue. 
Tinnunculus sparverius, Circus hudsonius , and Accipiter mexicanus 
are very common indeed. Other Hawks of Southern California, 
near this locality, are Buteo elegans , B. cooperi, and B. zonocercus, 
all of which have been detected by the tireless industry of Dr. 
Cooper. The last named, an interesting new species originally 
described from Guatemala by Mr. Sclater (Proc. Zool. Soc. 
1858, p. 130), was first obtained within the limits of the United 
States by Dr. Cooper; I myself rediscovered it on the Gila river 
in Arizona. 
Agelaus tricolor is the common Blackbird of this region. 
Familiar, tame, and unsuspicious, flocks of thousands continu¬ 
ally circle about our very heads, fill the streets of the little town, 
and blacken the housetops. I am ashamed to say how many I 
procured at a single discharge of my gun. I noticed that at 
this season the two sexes keep in a great measure in separate 
flocks. Of the many that I examined, not a single male was in 
perfect plumage. I never saw an A. phceniceus or A. guher- 
nator among them; but great numbers of Scolecophagus cyano- 
cephalus are their constant and familiar companions. 
The little Carpodacus frontalis had been my companion from 
the Bio Grande to the Pacific; and here I found “ Linnets/* 
as they are called, common enough. I was somewhat surprised 
to find them in full plumage, singing volubly, and apparently 
* This species is generically quite distinct from JEgialites or any other 
genus of Charadridce with which I am acquainted. I have elsewhere 
instituted a genus for it.
