1923 BIRDS OF THE SANTA R.ITA MOUNTAINS 25 



where dozens were seen flying- about camp in the evenings. One was taken by 

 Howell, August 18, 1918, at Continental, where they were abundant and he 

 flushed three from the ground among the mesquites in the day time. A night- 

 hawk, presumably of this species, was seen by us at a distance May 1, 1921, 

 flying over the mes<]uite slope a little below 4,000 feet, and one seen near 

 enough for identification. May 6, at Tucson. Between Tucson and Nicholson's 

 Ranch, on June 9, 1922, Vorhies saw "great numbers of Texas Nightliawks 

 in the road, not only in the valley but all the way up to camp," which was 

 reached about nine o'clock. "In many cases the automobile almost ran over 

 them before they flew up." Two or three years previously, Vorhies found 

 numbers of them dead in the road between Continental and Tucson, undoubt- 

 edly killed by cars in the night. 



Aeronautes melanoleucus. White-throated Swift 



Frequently seen flying overhead by Swarth in June, 1903, his camp being 

 within easy flying distance of Elephant Head, a vertical rock mass where, as 

 he inferred, they probably nest. One or two were seen by Howell in August, 

 1918, every time he went up to 7000 feet; and w^henever heavy clouds hung low 

 enough they were driven down to 5,000 feet, the altitude of his camp. On 

 December 24, 1920, January 14, and February 9 and 10, 1921, they were seen 

 by us at about 4,000 feet. Only one was seen at a time from camp on Febru- 

 ary 9 and 10, and at Continental, March 8 ; but two were seen on December 

 24 and 29, January 14, and April 8 and 9, and several April 13. Most of tliose 

 seen were going toward the mountains south of us rather than toM^ard the 

 Elephant Head cliffs west of us, but on April 13, when we were going to Ma- 

 dera Canyon, Swifts came rushing down from the mountains, perhaps from 

 the Madera region but perhaps from Elephant Head. 



Eugenes fulg-ens. Eivoli Hummingbird 



A juvenile was taken by Nelson, July 5, 1884, at Gardner's Ranch. A 

 large hummingbird, taken for the Rivoli, was shot by Howell, August 12, 1918, 

 from a pine on a very steep slope at 7,500 feet in Madera Canyon, but it fell 

 into "a great tangle of bracken" and he was unable to recover it. 



Cyanolaemus clemenciae. Blue-throated Hummingbird" 



A strikingly large hummingbird, with a long dark tail, was seen l)y us on 

 Mai'ch 29, 1921, in the top of a tall sycamore at camp, and with the glass we 

 thought we could detect the blue of the throat. It flew, however. Avithout 

 giving us a better view\ It has been reported, Swarth says, not only from 

 the Santa Ritas, but the Santa Catalinas, the Huachueas, and the Chiricahuas, 

 in Arizona, and the San Luis Mountains in New Mexico. 



"The Arizona form has been referred to under the name Cyanolaemus clemenciae
