Sayornis sayus (Bonaparte) 

 Say Phoebe 



Probably breeds along the eastern base of the mountains, 

 though we failed to find it doing so in the few places where it 

 was encountered. Observed as follows : a few seen the first week 

 in May in the vicinity of Cabezon ; a single bird observed sing- 

 ing on the brink of Deep Canon (3000 feet), May 31; a full- 

 grown juvenal secured at Vandeventer Flat, July 2, undoubt- 

 edly a wanderer from the desert below ; numerous about Hemet 

 Lake in August, when the late summer dispersal was well under 

 way. 



Two specimens were collected, both full-grown juvenals: 

 Vandeventer Flat, July 2 (no. 2295), and Hemet Lake, August 

 11 (no. 2987). 



Sayornis nigricans (Swainson) 

 Black Phoebe 



Distributed over the lower parts of the range, nowhere abund- 

 ant, but present at all suitable spots. At Kenworthy on June 5 a 

 nest which the young had just left was found at the entrance of 

 a small tunnel. 



Found nesting in Strawberry Valley, 6000 feet, probably the 

 uppermost breeding limit of the species in these mountains. 

 Here, on July 17, a nest was found built on the window casing 

 of a deserted cabin, and containing four half-grown young. 

 Although no nests were discovered on the desert side of the 

 range the presence of a single bird in Palm Canon at about 

 3000 feet, on June 13, two families at the mouth of Palm Canon, 

 June 14, and a single bird by one of the pools in Deep Canon. 

 June 21, may be taken as evidence of the probable breeding of 

 the species at these points. Adults, apparently breeding, were 

 taken at Cabezon in May, where, however, they were not common. 



In the late summer they increased in numbers, and also 

 wandered to higher elevations, being seen in July in Tahquitz 

 Valley (8000 feet) and in Round Valley (9000 feet). They were 

 particularly abundant about the shores of Hemet Lake, in 

 August.
