THE CONDOR 
Voi,. VII 
Lophortyx gambeli. Gambel Partridge. Frequently seen and oftener heard 
calling in the ravine below the mountains. 
Columba fasciata. Band-tailed Pigeon. A pair or two were frequently seen 
in the vicinity of our camp. Towards the end of our stay they became much more 
abundant, and the last day or two a number of quite large flocks were seen. 
Zenaidura macroura. Mourning Dove. Very abundant along the lower 
canyons. Most of the birds seen were young of the year, full grown. 
Melopelia leucoptera. White-winged Dove. Very common in the lower parts 
of the mountains, hardly any being seen about our camp. But one nest was found, 
and of the specimens secured hardly any had the appearance of beingbreeding birds. 
Cathartes aura. Turkey Vulture. Frequently seen flying overhead. 
Accipiter v. pacificus<o Western Sharp-shinned Hawk. One or two seen. 
Accipiter cooperi. Cooper Hawk. Several seen. A nest containing young 
was found in the canyon; but an adult female taken on June 23 was evidently 
not breeding. 
Buteo b. calurus. Western Red-tail. One or two seen. Not common. 
Buteo abbreviatus. Zone-tailed Hawk. Two specimens were secured by Mr. 
Stephens. One was a fine old female, but the second, a male, probably of the pre- 
vious year, lacks the pure white bands across the tail, but has the tail feathers 
numerously and irregularly banded with ashy white, and with numerous white 
spots showing through the black of the breast. The resemblance that this hawk 
bears to a turkey buzzard while flying, both in style of coloration and manner of 
flight, is so close that it is exceedingly difficult to distinguish between the two. 
Buteo swainsoni. Swainson Hawk. A few seen, one in the canyon at an al- 
titude of about 6000 feet. 
Falco s. phaloena. Desert Sparrow Hawk. F'airly common along the foothills. 
Geococcyx californianus. Rood-runner. Seen occasionally but not at all common. 
Dryobates s. bairdi. Texas Woodpecker. Fairly common along the lower ra- 
vine and out on the mesa. 
Dryobates arizonae. Arizona Woodpecker. Very few of the birds seen. Pro- 
bably in better years they would be found in abundance, as the country is admir- 
ably suited to their wants. 
Melanerpes f. aculeatus. Ant-eating Woodpecker. Fairly common in the 
lower parts of the mountains. 
Colaptes c. collaris. Red-shafted Flicker. A few of the birds seen. Not 
very common. 
Antrostomus v. macromystax. Stephens Whip-poor-will. A single bird seen 
at an altitude of about 7000 feet. None were heard calling at any time, the 
drought having apparently driven them away almost entirely. 
Phalaenoptilus nuttalli. Poorwill. Frequently heard calling about camp of 
an evening. 
Chordeiles a. texensis. Texas Nighthawk. Fivery evening dozens of night- 
hawks appeared flying about the camp. None were flushed from the ground, and 
no eggs were found. Henryi was not observed at any time. 
Aeronautes melanoleucus. White-throated Swift. Frequently seen flying 
overhead. Some distance from our camp was a projecting spur of the mountain, 
ending in a huge cliff, so precipitous that viewed from a point ten or fifteen miles 
to the northward, the mountain range presents the appearance of having been 
abruptly chopped off with a huge hatchet; and here, doubtless, the swifts find an 
abundance of nesting sites. We did not feel encouraged to look for their eggs.
