42 RIDGWAY ORNITHOLOGICAL CLUB. 



males and females — taken about the middle of June show signs of 

 having incubated. 



32. Melanerpes formicivorus bairdi Ridgw. [Cali- 

 fornia Woodpecker'). Common near San Gorgonio. A nest 

 found May 30th contained two young birds and three addled eggs, 

 two more young had just left the nest. Iris white, tinged with red. 



33. Melanerpes uropygialis (Baird). {Gila Wood- 

 pecker). Found only at Yuma, where they were not common. A 

 nest found May 4th was excavated in a growing willow on the 

 edge of a slough. Eggs three; incubation commenced. The $ 

 was very solicitous about her nest, and would not leave the tree in 

 which it was built. 



Woodpeckers are not common at Yuma, probably owing to 

 the timber being too small to furnish nesting sites. Colaptes chry- 

 soides has been taken here, but is probably only a straggler. 



34. Colaptes cafer (Gmel.). {Red-shafted Flicker). 

 Common. With this species the male incubates as well as the 

 female. 



35. Chordeiles texensis Lawr. {Texan JVighthawk). 

 Noted at Yuma and in Bear Valley. Is by no means commons 

 only four being taken. A? obtained May 5th was nearly ready to 

 lay. 



36. Micropus melanoleucus (Baird). ( White-throated 

 Szvift). Rare, especially northward. Two $ taken April 10th 

 and 19th in Cohuilla Valley. 



37. Trochilus alexandri Bourc. & Muls. {Black-chinned 

 Hummingbird). This species was seen April 3rd in Cohuilla Val- 

 ley; they were most common on the 13th, when they were found 

 in company with T. coslce, T. rnjus, and T. alleni. They are only 

 migrants in this locality. One $ was taken at Yuma, May 5th. 

 In the San Benardino Valley they are not uncommon and breed. 

 A nest taken May 22nd, was built in a willow eight feet from the 

 gi-ound and contained two eggs in which incubation had com- 

 menced. None were seen in Bear Valley. 



38. Trochilus cost.e (Bourc). {Costa^s Hummingbird)' 

 On the 3i-d of April, while passing a bush in the Cohuilla Valley 

 a $ of this species was observed to fly out in such a manner as to 

 make me think she had a nest near by. In a few minutes she 

 returned, and, after hovering around a little, settled on the nest. It 

 was built in a bush of Larrea mexicana about two feet from the 

 ground and contained two fresh eggs. The $ was afterwards shot.
