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 Sau Pedro we find Archibuteo 

 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 raay 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, CirciLS 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. 



AgelcEus 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. phoeniceus or A. guber- 

 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 Rio Grande to the Pacific ; and here I found " Linnets,^' 

 as they are called, common enough. 1 was somewhat surprised 

 to find them in full plumage, singing volubly, and apparently 



* This species is genericallj' quite distinct from jlSgialites or any other 

 genus of Charadrid(e with which I am acquainted. I have elsewhere 

 instituted a genus for it.
