ao2 THE CONDOR I VoL. V or immature males in the Hualapai Mountains, which from their large size I sup- pose to be of this species. Tyrannus verticalis. Arkansas Kingbird. Seen at Twenty-nine Palhas, Needles, Little Meadows, Beale Spring, Big Sandy Creek, Bill Williams River and Ehrenberg. They were rather common at most of these places. Tyrannus vociferans. Cassin Kingbird. Saw one at the base of Providence Mountains and several in the Hualapai Mountains, mostly above 6,ooo feet altitude. Myiarchus mexicanus magister. Arizona Crested Flycatches. Seen only among the giant cactuses at Big Sandy Creek, where a set of four eggs was taken from an old woodpecker's hole in a giant cactus, July 20. Myiarchus cinerascens. Ash-throated Flycatcher. None seen in the higher parts of the mountains but generally distributed elsewhere, as I saw the species in the foothills, valleys, plains, and even in the deserts where were growing occa- sional mesquite or other shrubs. They were usually seen singly. Say0rnis saya. Say Flycatcher. Seen at Providence Mountains, Needles, Beale Spring, Big Sandy Creek and Ehrenberg, but they were not common at any of these places. Sayornis nigricans semiatra. Western Black Phoebe. Not common. Seen only along Big Sandy Creek, Bill Williams River, and Colorado River. C0nt0pus richards0ni. Western Wood Pewee. Seen at Twenty-nine Palms as migrants, and at Providence Mountains where they were rather common and ap- parently resident. Empid0naxdifficilis. Western Flycatcher. Hualapai Mountains, rare; Bill Williams River, one migrant, the last of July. Pyr0cephalus rubineus mexicanus. Vermilion Flycatcher. Big Sandy Creek, rather common; Bill Williams River; Colorado Valley near Ehrenberg, not com- mon, as the southward movement had commenced before I got there in August. A farmer in the new settlement oi Cibolo, twenty-five miles below Ehrenberg, told me he had brought in a swarm of bees to start an apiary, and that these flycatchers had eaten so many of the bees that the swarm died out. 0tocoris alpestris ammophila. Mob ave Horned Lark. Occasionally seen along the Santa Fe R. R. in the eastern part of the Mobave Desert. Cyanocitta stelleri diademam. Long-crested Jay. I shot one in the Hualapai Mountains, but saw no others. Aphelocoma woodhousei. Woodhouse Jay. I saw several jays on the Provi- dence Mountains that I believe were of this species, but they were very wild and on such rugged mountain sides that I was unable to get any. I saw a few on the Hualapai Mountains. These were mostly immature birds. Corvus corax sinuatus. American Raven. Seen occasionally throughout the region traversed. Molothrus ater. Cowbird. Generally distributed. Xanthocephalus xanthocephalus. Yellow-headed Blackbird. Seen migrating at Twentp-nine Palms, and at Big Sandy Creek, Bill Williams River, and at Fhrenberg. 'Agelaius phceniceus neutralis. San Diego Redwing. Saw a few redwings at Big Sandy Creek and near Ehrenberg. Icterus parisorum. Scott Oriole. I saw and heard quite a number of these orioles on Providence Mountains, where they were undoubtedly breeding. They were also common at Beale Spring in July, where they were feeding on figs and peaches in the orchard.
