1923 BIRDS OF THE SANTA RITA MOUNTAINS 31 



by Swartli, in June, 190)3, "({uite common along the lower canyons," and sev- 

 eral were taken which were evidently not breeding. They were reported by 

 Howell, July 28- August ]5, 1918, "exceedingly abundant, especially in the 

 Upper Sonoran and low Transition canyon bottoms," none being noted above 

 G,000 feet. Ten adults were taken July 80-August 10, 1918. 



Empidonaoc difficilis difficiiis. Western Flycatcher 



An adult was taken by Nelson, June 14, 1884, at Gardner's Ranch and 

 four others by Howell, August 1, 6, and 10, together with an immature on 

 August 4, 1918, two or three being seen later, in Madera Canyon, between 

 about 5,000 and 6,000 feet. An Empidonax taken for this species, although 

 seen only in the shade of the live oaks was found by me on March 25, April 29, 

 and May 2, 1921, not far from camp. 



Empidonax traillii traillii. Traill Flycatcher 



One was taken by Henshaw, September 1, 1874, at Camp Crittenden, and 

 one by Howell, August 15, 1918, at Continental, while three were seen alto- 

 gether on August 15 and 18, 1918, in the mesquite. 



Empidonax hammondi. Hammond Flycatcher 

 One was taken by Stephens, May 12, 1881, in Madera Canyon. 



Empidonax fulvifrons pygrnaeus. Buff-breasted Flycatcher 



One was taken May 17, 1881, by Stephens, but he reported it as rare. A 

 single individual was seen by Lusk, April 20, 1899, "low down in the foot- 

 hills of the Santa Ritas." A few were seen by Swarth in June, 1908, "in the 

 pines in the very highest parts of the range." One or two were seen by me 

 during the snowstorm of April 5, 1921, at the Nicholsons', in the live oaks 

 and on the fence of the ranch corral. 



Pyrocephalus rubinus mexicanus. Vermilion Flycatcher 



Found by Stephens during May, 1881, in Madera Canyon. Five taken by 

 Nelson, June 16-29, 1884, at Gfardner's Ranch. Reported by Swarth in June, 

 1903, as "fairly common in the lower canyons." Most of those seen by us 

 were found in the Santa Cruz bottoms near Continental in March, 1921 — 

 where Howell saw about four, August 15-] 9, 1918 — but on April 2, one was 

 seen near the Nicholson ranch-house and on April 5, during the snow storm, 

 one spent the day flycatching under the protection of the oaks. On April ]6, 

 one was seen a little above 4,000 feet. On our way to Madera Canyon on April 

 L3, a pair was found in the gulch below the canyon and the male was seen 

 on tiie mesa, giving his flight song high over the mesquites. 



Camptostoma imberbe. Beardless Flycatcher 

 A striking, unusual song was first heard on March 14, 1921 ; then on
