"^^locfs^^ ] HoLLisTER, Birds of the Region abont Needles, Cal. 459 



beyond the line some miles into Nevada. Specimens were secured in 

 California ten miles north of Needles, where the loud calls and drummings 

 were heard from morning until night. One nest was in a small blasted 

 stub standing some distance from shore in a large lagoon. 



Phalaenoptilus nuttalli. Poor-Will.^ At Goffs one was heard caUing 

 on the evenings of April 15 and 16, and while camped on the Colorado 

 River near the Nevada-California line we heard one each night on the 

 higher mesa to the westward. Mohave name, To-16wk.' 



Chordeiles acutipennis texensis. Texas Nighthawk. — Very abundant 

 along the Colorado River. The nighthawks here spend the day in the 

 thickets of arrow- weed from which I frequently flushed them. At night 

 they swarmed about the town of Needles, especially at the station, where 

 the insects were no doubt attracted by the lights. The switching engine 

 seemed not to bother the birds in the least and I often saw them dart in 

 and out of the thick black smoke close to a puffing freight. On the edge 

 of the mesa at Fort Mohave one evening, just before the time for the night- 

 hawk's flight, I saw and heard one give the peculiar chuckling call, which 

 was 'accompanied by a most curious bobbing of the bird's head and body. 

 Mohave Indian name, Oh-roo'. 



Aeronautes melanoleucus. White-throated Swift. — Several times 

 when I climbed to near the highest rocky point on New York Mountain I 

 saw four of these birds swiftly flying around the peaks. 



Calypte costse. Costa Hummingbird. — Hummers were common in 

 the neighborhood of the Colorado River and about the watered gulches on 

 New York Mountain. The only specimen taken was shot high up on the 

 movmtain and proved to be of this species. The Mohaves call all the 

 hummingbirds Yni'-yin-a. 



Tyrannus verticalis. Arkansas Kingbird. — Abundant along the 

 Colorado River. A nest which I examined at Needles on May 18 was 

 placed on the platform of a steel windmill tower in town and contained 

 three eggs. Specimens collected. Mohave name, Sah-kahl-cheer'-kah. 



Myiarchus cinerascens. Ash-throated Flycatcher. — Common at 

 Needles and several seen on New York Mountain, at both of which places 

 specimens were secured. 



Sayornis saya. Say Phcebe. — A single bird seen at Goffs on April 16. 



Empidonax griseus. Gray Flycatcher. — One taken at Goffs, April 

 15. It was a single bird and was feeding among the higher creosote bushes 

 along a dry wash. 



Pyrocephalus nibineus mexicanus. Vermillion Flycatcher. — Three 

 specimens secured on the California side of the Colorado River ten miles 

 above Needles where the bird was fairly common about the shores of 

 lagoons. Several were seen also in Nevada a short distance above the 

 boundary monument. Unlike most flycatchers this species rarely returned 

 to the old perch after darting out to catch an insect, but usually flew on 

 and on, lighting on a new bush after each dash. A nearly full grown 

 young was taken May 20.
