berries of various kinds, but the Robins were gone, where, or why, it is 

 hard to say. 



Lophortyx gambeli. Gambel Partridge. From Benson to the foothills of the 

 Rincon Mountains this species was seen in the greatest abundance. Though so 

 common around Benson, it ranges in the valley of the San Pedro River hardly 

 more than twenty miles or so south of that place, at least in any abundance. 



Callipepla squama ta. Scaled Partridge. None were seen in the Rincon 

 Mountains, though the ground was of a character that should be suitable to the 

 species. As we traveled south from Benson on the train many flocks of Scaled 

 Quail were seen along the San Pedro River, while the Gambel Quail was no 

 longer observed. 



Cyrtonyx montezumae mearnsi. Mearns Partridge. Abundant in the Huachu- 

 cas, where they were seen from the base of the mountains (about 4,000 feet) up to 

 the divide (about 9,000 feet). One flock was seen in the Rincon Mountains. 



Columba fasciata. Band-tailed Pigeon. A small flock was seen in the Rincons 

 September 22, the only ones observed in this region. In the Huachucas also, but 

 few were seen, and they lessened in numbers during the whole of our stay, until 

 by November 1 hardly one was to be found. An old bird was observed feeding 

 a young one on October 12. Nearly all that were seen were unusually tame and 

 unsuspicious. 



Zenaidura macroura. Mourning Dove. During the winter months the 

 Mourning Dove appears to leave this region almost entirely; for a few stray birds 

 seen in the Rincons on various occasions, and one or two observed in the foothills 

 of the Huachucas, were all that we came across. 



Cathartes aura. Turkey Vulture. A good many were seen in the vicinity of 

 Benson the latter part of September, but they had already disappeared from the 

 Huachucas. Not one was seen during the whole of our stay in that range. 



Circus hudsonius. Marsh Hawk. Several birds seen along the San Pedro 

 River on November 8 were the only ones observed. 



Accipiter velox. Sharp-shinned Hawk. Early in October this species was 

 seen in considerable numbers, evidently migrating, for a few weeks later but few of 

 the birds could be found. 



Accipiter cooperi. Cooper Hawk. A few were seen in the Rincons, while in 

 the Huachucas, during the first two weeks in October, they were exceedingly 

 abundant. There were a great many chickens and pigeons on the ranch where we 

 were staying, and during that time there was not a day on which at least one 

 Cooper Hawk did not make an attempt on the poultry yard. Nearly all of these 

 marauders were immature birds, and I did not see one succeed in carrying anything 

 away with him, as they seemed to become confused at the uproar they invariably 

 stirred up. They were so quick and unexpected in these attacks though, that not 

 one was shot in the act. Toward the end of October their numbers were greatly 

 lessened, and it was evident that nearly all had passed on further south. 



Buteo borealis calurus. Western Red-tail. Quite common in the Huachucas 

 from base to summit, and, as a rule, tame and unsuspicious. In the foothills they 

 were frequently seen hunting the common "ground squirrel" of the region {Cttel- 

 lus granimiiriis) . On the morning of October 21 a hawk made an exceedingly ill- 

 advised and abortive attempt on the chicken yard, and his strange appearance made 

 me start in pursuit. I secured the bird, and at the time was puzzled to know 

 what it was, but it is evidently an immature caliirits in exceedingly dark plumage. 

 The whole bird is uniform dark brown, decidedly glossy on the back, and with 

 most of the feathers of the lower parts edged with paler brown. The upper breast
