i2i. Thryothorus bewickii spilurus (Vig.). [Vigor's 



Wren). But one noted. A young, near San Gorgonio, May 25th. 



122. Troglodytes aedon parkmanii (Aud). Parkman's 

 Wren). Common: the House Wren of this section. I have no 



record of its occurrence at Yuma in Summer. 



123. Cistothorus palustris (Wils.). {Long-billed Marsh 

 Wren). Not common in the Cohuilla Valley although may be 



found about the water. Generally distributed in marshy localities. 



124. Certhia familiaris Americana (Bonap.). {Brown 

 Creeper). Only one noted. A <$, Bear Valley, June 10th. 



125. Sitta carolinensis aculeata (Cass.). [Slender-billed 

 Nzithatch). Found only in the pine region. 



126. Sitta pygm^ea Vig. {Pygmy Nuthatch). Not com- 

 mon. Found only in Bear Valley, where five were taken. 



127. Parus inornatus Gamb. {Plain Titmouse). This is 

 a very rare species here. I have not seen one before in several 

 years. Two were shot in the chaparral near San Gorgonio and 

 two in Cajon Pass. 



128. Parus gambeli Ridgw. {Mountain Chickadee). Sev- 

 eral were seen near San Gorgonio May 29th. They were probably 

 breeding. Not uncommon in Bear Valley. 



June 10th I saw a 3 of this species go to a pine stub and fly 

 away again, I enlarged the opening and was surprised to find the 

 $ on the nest. I caught her in my hand. The nest was placed in 

 what was originally a "weather chick" in the wood, which had 

 rotted away some, the pieces being in all probability carried out by 

 the birds. It contained seven eggs far advanced in incubation, 



129. Psaltriparus minimus californicus Ridgw. {Cali- 

 fornian Bush-til). Common in San Bernardino and Bear Valleys 

 where they breed. Young were taken as early as May 19th. 



130. Auriparus flaviceps (Sund.). {Verdin). A young 

 $ was taken from the nest (from which another flew on my ap- 

 proach) in Cohuilla Valley, April 2d. Another, together with the 

 adult $, was also taken the same day and in the same locality. They 

 were probably the parent and another young of the same brood. 

 The adult bird would have laid again on the morrow. 



At Cohuilla Valley this species was more common than I had 

 expected to find them. Their nests are comparatively easv to find, 

 being very bulky for so small a bird. They are usually found near 

 the ends of the branches of some thorny tree or shrub, commonly 

 the mesquite in this locality, which grows low, often sprawling
