Dendroica aestiva. Yellow Warbler. Migrants, mostly immature, were seen 
at Big Sandy Creek the latter part of July. 
Dendroica nigrescens. Black-throated Gray Warbler. Rather common in the 
higher parts of the Providence Mountains in June. 
Icteria virens longicauda. Long-tailed Chat. Found only in willow thickets 
in the lower valleys, such as that of the Colorado River and Big Sandy Creek. 
Noisy, as usual, in summer. 
Wilsonia pusilla pileolata. Pileolated Warbler. Seen migrating northward 
at Twenty-nine Palms, May 17, and below Ehrenberg, going southward in August. 
Mimus polyglottos leucopterus. Western Mockingbird. I observed one at 
base of Providence Mountains, one at lower edge of the pine belt in Hualapai 
Mountains, two at Big Sandy Creek and several near Ehrenberg. 
Toxostoma curvirostre palmeri. Palmer Thrasher. Big Sandy Creek, rare. 
Toxostoma bendirei. Bendire Thrasher. Two shot at Beale Spring were the 
only ones observed. 
Toxostoma lecontei. Leconte Thrasher. Seen at Twenty-nine Palms; one 
shot at Danby (a small station on the Santa Fe R. R., in the Mohave Desert); two 
young of the year shot at base of Providence Mountains. 
Toxostoma crissale. Crissal Thrasher. Seen at a number of places, including 
The Needles, Little Meadows, Beale Spring, Big Sandy Creek, Bill Williams River 
and Hualapai Mountains. The latter was in a location totally unlike an)^ in which 
I have previously seen this species, being in the lower edge of the pine belt, as an 
immature bird was shot at 6000 feet altitude, July 8, and a new nest was found in 
the pinyon and juniper belt a few days previously. 
Heleodytes brunneicapillus anthonyi. Desert Cactus Wren. Seen in Morongo 
Pass; shot at base of Providence Mountains; brood of young seen at Little Mead- 
ows; also seen at Beale Spring, Big Sandy Creek and near Ehrenberg. Not com- 
mon at any of these places. 
Salpinctes obsoletus. Rock Wren. Heard on Providence Mountains; a family 
seen below Beale Spring the latter part of June; rather common on Hualapai 
Mountains. 
Catherpes mexicanus conspersus. Canyon Wren. Providence Mountains and 
Hualapai Mountains; not common.

part of the Hualapai Mountains. 
Sitta pygmaea. Pygmy Nuthatch. Rather common in the pine forests of the 
Hualapai Mountains. 
Parus inornatus ridwayi. Gray Titmouse. I saw two in the Providence 
Mountains. 
Psaltriparus plumbeus. Lead-colored Bush-tit. I saw a small flock in the 
Providence Mountains at 6300 feet altitude; they were rather common in the Hu- 
alapai Mountains up to 6500 feet altitude. 
Auriparus flaviceps. Verdin. Rather common at most localities visited except 
in the mountains. 
Polioptila caerulea obscura. Western Gnatcatcher. Seen in the Providence 
and Hualapai Mountains, but not common in either range.
