Junv, t9o3[ THE CONDOR tot Mountains I heard some small owl, probably a Olaueidium, several night% but was unable to locate it in the pines. Micr0pallas whitneyi. Elf Owl. Above the Needles, on the Arizona side I heard a small owl that may have been this species, but was unable to get a shot at it. This was about twenty miles below Dr. Cooper's type locality. He stated that he obtained but one specimen. It is probable that elf owls straggle to the Colo- rado River in the spring migrations. I looked carefully along the Colorado at all places visited but found no other evidence of its occurrence there. On Big Sandy Creek, above Signal, we secured three elf owls, finding them by their notes and calls, and shooting them with light charges when seen dimly in trees or bushes in the starlight. Others were heard. The favorite breeding places are old wood- pecker holes in giant cactuses. I opened a number of these holes in July, but the only positive evidence that I found of their using the cavities was the finding of two dried carcasses of nearly grown young owls. 6e0c0ccyx calif0rnianus. Roadrunner. We saw but few roadrnnners and these were mostly near the Colorado River. C0ccyzus americanus 0ccidentalis. Californian Cuckoo. Saw one near The Needles and heard others there about the middle of June, and a month later saw and heard others at Big Sandy Creek. Dry0bates vil10sushy10scopus. Cabanis Woodpecker. Hualapai Mountains. Not co?nmon. Dry0bates scalaris bairdi. Baird Woodpecker. Rather common over most of the route traveled in Arizona. except in the Hualapai Mountains. l?elanerpes f0rmiciv0rus. Ant-eating Woodpecker. I saw several of these woodpeckers, apparently a family, on the Hualapai Mountains, between 6000 and 7000 feet altitude. l?elanerpes ur0pygiali s. Gila Woodpecker. More or less common in the tim- ber along the Colorado and Big Sandy Creek. C01aptes cafer c011aris. Red-shafted Flicker. Seen on the Hualapai Mrs. and near Ehrenberg in the Colorado River bottoms. Not common at either locality. C01aptes chrys0ides. Gilded Flicker. Seen only near Big Sandy Creek, where they were rather common. Some were seen feeding on the fruits of the giant cac- tuses on the mesa, but they principally frequented the willow thickets near the stream. No woodpeckers were seen on the Providence Mountains, though this range is fairly well timbered, and seemingly well adapted for their homes. Phalsen0ptilus nuttalli. Nuttall Poorwill. Heard in nearly every locality where collections were made. Two shot at Big Sandy Creek and one at Bill Wil- liams River. Ch0rdeiles virginianus henryi. Western Nighthawk. Seen only on the Hual- apai Mountains where they were rather common. Ch0rdeiles acutipennis texensis. Texan Nighthawk. More or less common along most of the route traveled, except on the higher mountains and barren deserts. Aer0nautes melan01eucus. White-throated Swift. Rather common on the Providence Mountains and Hualapai Mountains. I saw a few near Ehrenberg. Tr0chilus alexandri. Black-thinned Hummingbird. Two young of the year were on the wing at Twenty-nine Palms, May t8. Calypte c0stse. Costa Hummingbird. Noted at Providence Mountains, Little Meadows and Beale Spring, but they were not common. Selasph0rus platycercus. Broad-tailed Huxnmingbird. I saw several females
