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 Palms, 
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,ooc 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. 
Sayornis 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. 
Contopus richardsoni. Western Wood Pewee. Seen at Twenty-nine Palms as 
migrants, and at Providence Mountains where they were rather common and ap- 
parently resident. 
Empidonax difficilis. Western Flycatcher. Hualapai Mountains, rare; Bill 
Williams River, one migrant, the last of July. 
Pyrocephalus 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 of 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. 
Otocoris alpestris ammophila. Mohave Horned Lark. Occasionally seen along 
the Santa Fe R. R. in the eastern part of the Mohave Desert. 
Cyanocitta stelleri diademata. Long-crested Jay. I shot one in the Hualapai 
Mountains, but saw no others. 
Aphelocoma woodhousei. W^oodhouse 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 phoeniceus 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.
