7 8 THE CONDOR VoL. VII L0ph0rtyx gambeli. Gambel Partridge. Frequently seen and oftener heard calling in the ravine below the mountains. C01umba 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 macr0ura. Mourning Dove. Very abundant along the lower canyons. Most of the birds seen were young of the year, full grown. Me10pelia leuc0ptera. 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. pacificusa. Western Sharp-shinned Hawk. One or two seen. Accipiter c00peri. Cooper Ha?'k. Several seen. A nest containing young was found in the canyon; but an adult female taken on June 2 3 was evidently not breeding. Bute0 b. calurus. Western Red-tail. One or two seen. Not common. Bute0 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. Bute0 swains0ni. Swainson Hawk. A few seen, one in the canyon at an al- titude of about 6ooo feet. Palco s. pha10ena. Desert Sparrow Hawk. Fairly common along the foothills. Ge0c0ccyx calif0rnianus. Rood-runner. Seen occasionally but not at all common. Dry0bates s. bairdi. Texas Woodpecker. Fairly common along the lower ra- vine and out on the mesa. Dry0bates ariz0na?. Arizona Woodpecker. Very few of the birds seen. Pro- bably in better years they would be found in abundance, as the country isadmir- ably suited to their wants. Melanerpes f. aculeatus. Ant-eating Woodpecker. Fairly comnlon in the lower parts of the mountains. C01aptes c. c01taris. Red-shafted Flicker. A few of the birds seen. Not very common. Antr0st0mus v. macr0mystax. Stephens Whip-poor-will. A single bird seen at an altitude of about 7oo0 feet. None were heard calling at any time, the drought having apparently driven them away almost entirely. Phala?n0ptilus nuttalli. Poorwill. Frequently heard calling about camp of an evening. Ch0rdeiles a. texensis. Texas Nighthawk. Every evening dozens of night- hawks appeared flying about the camp. None were flushed from the ground, and no eggs were found. l?renrfi was not observed at any time. Aer0nautes melan01eucus. 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. a. See Nelson, Proc. Bio]. $oc. Washington, XIII, April i8, x9o5, p. 122.
