Brewster on Bird* from Arizona and New Mexico. J I 



approach to the type of arz'zonee, in its large size (wing 6.50) , 



in the great length of the rictal bristles, and in the decided taw- 

 ny-ochraceous of the lores and auriculars. The gular-crescent is 

 however mixed with white, and the white areas of the tail are 

 nearly as extended as in typical voci ferns. It is possible that 

 this bird represents the form characteristic of Northern Mexico 

 but in the absence of more satisfactory data regarding its history, 

 the characters which it presents have no direct bearing on the 

 case in hand. Specimens intermediate between vociferns and 

 arizonce are of course to be expected and the Guanajuato example 

 is simply one of these. 



The most western point within the United States from which 

 the Whip-poor-will has been previously announced is the valley of 

 the Lower Rio Grande in Texas, where both Merrill and Sennett 

 found it in small numbers. 



The distribution of the Arizona form must be exceedingly 

 local. Mr. Stephens has never before met with it. and Mr. Hen- 

 shaw failed to detect it during his very thorough explorations. 

 Dr. Cones, however, probably heard it at Fort Whipple* in i86v 

 but no specimens were actually obtained there. 



In the Chiracahua Mountains it is apparently not uncommon, to 

 judge from the following notes which accompanied my specimen. 

 •■ I have heard several of these Whip-poor-wills singing at one 

 time and am told that they were heard here last year. I hear A, 

 nnt tall i every evening. They keep high up the mountain sides, 

 while A. vociferns affects the lower part of the canons. This is 

 the only locality east of the Missouri River where I have found 

 the latter species." 



In a recent letter Mr. Stephens adds : "I heard the first Whip- 

 poor-will about the middle of May. By June 1, they were as 

 common as I ever knew them to lie in the East. Sometimes I could 

 hear three or four whistling at once. They were very restless and 

 rather shy, so I got only the specimen I sent you, and a female 

 shot in the daytime. The latter flew off her nest, which, ;is 

 usual, was only a very slight depression in the ground, but in 

 this case was overhung by a rock. The single egg (now before 

 me) is plain white, with very faint brow ish spots, so faint that 

 one would hardly notice them. She would have laid no more. 

 This was on July 4. 1880. The people in the canon said they
