BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 111 
Numerous examples of this species in my collection from Lower California, 
Arizona, and western Mexico, show no appreciable geographical variations in 
respect to either size or color, but they average a trifle smaller and, as a rule, 
are somewhat lighter colored than a number of Texas specimens in the col- 
lection of the late Mr. Sennett. 
Mr. Frazar saw the first Texan Nighthawk at Triunfo on the evening of 
April 15. It was next met with on the Sierra de la Laguna, where one or two 
were observed the last week in May. At Triunfo the birds were abundant 
during the last three weeks of June, appearing regularly every evening near 
the ranch, and skimming back and forth close over a large wood pile, which 
evidently harbored insects on which they were feeding. After a succession of 
heavy showers which occurred at this place early in July they suddenly and 
wholly disappeared. At San José del Cabo a few were seen at intervals 
through the autumn up to November 11, and several were observed near San- 
tiago on December 3. Mr. Belding found the species ‘‘ abundant at San José 
after April 23,” but he says that it was “rarely seen at La Paz.” As the 
latter statement presumably refers to some date or dates between December 
15, 1881, and March 21, 1882, it seems fair to assume that the December in- 
stance noted by Mr. Frazar was not exceptional, and that at least a few birds 
regularly winter in the Cape Region. Mr. Frazar obtained a set of two eggs, 
slightly incubated, at Pierce’s Ranch, on July 20. 
The Texan Nighthawk seems to be generally distributed throughout the 
central and northern portions of the Peninsula, although, judging by Mr. 
Bryant’s experience, it is nowhere very common to the northward of La Paz. 
Its extralimital range includes the lower border of the United States from 
southern California to eastern Texas, southward to Central America. 
Chaetura vauxii (Towns.). 
Vaux’s SwIrt. 
At San José del Cabo on September 24, and again on November 2, Mr. 
Frazar saw “a small black Swift”? which he thought belonged to this species, 
and which, indeed, could not well have been anything else. On each occasion 
only a single bird was observed, but the one seen in September was accom- 
panied by a number of Barn and Eave Swallows. Chaetura vauaxit was of 
course to be expected in this region, at least as a migrant, but it has not been 
reported up to this time, although it was observed by Mr. Belding in May, 
1885, between San Rafael and San Pedro Martir, in the northern portion of 
the Peninsula (Bryant). 
Vaux’s Swift is found on the Pacific slope from British Columbia south into 
Mexico. It is not known to breed south of San Francisco.
