108 THE CONDOR VOl,. X berries of various kinds, but the Robins were gone, where, or why, it is hard to say. Lophortyx gainbell. 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 squamata. 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 montezuma? 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 Rincon? 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 acros.s.. 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. Accipite. r 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 (Citd- lus g'rammurus). 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 calurus 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
