Petrochelidon lunifrons. Cliff Swallow. 



This widely distributed species was found breeding in various locali- 

 ties visited by the expedition. I u Nevada Dr. Merriam found a colony 

 breeding in the canon at the lower end of Vegas Wash, May 3, and saw- 

 several at the Bend of the Colorado, May 4; he found it common in 

 Pnhranagat Valley, May 22-20, and in Oasis Valley, June 1. In Utah 

 he saw a colony which was breeding near St. George, in the Lower Santa 

 Clara Valley, where many nests were found on the red sandstone cliffs 

 a mile or two from the settlement. 



The cliff swallow was common in Owens Valley, California. It Avas 

 seen along the edge of the lake at Keeler, May 30- June 4; at the mouth 

 of the canon above Lone Pine, June 12; and Mr. Stephens found it 

 common at Haway Meadows, May 12-14; abundant at Olaucha, May 

 16-23 ; at Ash Creek, May 30 to June 3 ; breeding in thecanon at Benton, 

 July 9-10 ; and not common at the Queen mine, Nevada, July 11-16. Mr. 

 Nelson saw it on Willow Creek in the Panamint Mountains, the last of 

 May, and found it at the head of Owens Eiver, in the Sierra Nevada, 

 up to 2,100 meters (7,000 feet) altitude. It was common in Kern Val- 

 ley, July 3-13, and in Walker Basin, July 13-16. At the latter place a 

 number of nests were found fastened against the ceiling and walls of 

 the rooms in several of the deserted buildings. Dr. Merriam found it 

 breeding commonly at Kernville, under the eaves and piazzas of houses, 

 June 23, and in the Canada de las Uvas, under the eaves of Old Port 

 Tejon, June 28-29. 



At Twin Oaks, in western San Diego County, he was shown a large 

 sycamore tree on the outside of which these swallows used to fasten 

 their nests, and was told that after heavy rains the nests were fre- 

 quently washed down in great numbers. The species was common at 

 Bakersfield, in the San Joaquin Valley, July 17-20, and Mr. Stephens 

 found it not uncommon at Beche Canon, near San Bernardino, Sep- 

 tember 22-24. 



Chelidon erythrogaster. Barn Swallow. 



The barn swallow was found nowhere common except in Owens Val- 

 ley, California. It was first seen at Ash Meadows, Nevada, where two 

 were noted, March 19. In the same State, Dr. Merriam saw one at 

 Mount Magruder, June 8; one in Oasis Valley, June 1; a number in 

 Pahranagat Valley, May 22-26, where it was doubtless breeding, and 

 several near Bunkerville, in the Virgin Valley, May 7-8. BTe saw a sin- 

 gle bird near St. George, in the Lower Santa Clara Valley, Utah, about 

 the middle of May. 



Mr. Nelson saw it as a migrant on the divide between Panamint and 

 Saline valleys, the last of May, and at the head of Willow Creek, in 

 the Panamint Mountains, about the same time. He saw barn swallows 

 at the head of Owens Valley in the White Mountains, at the head of 

 Owens Biver, and also in the Yosemite Valley. Mr. Stephens found it
