69. Geococcyx calif ornianus. Roadrunner. — Noted now 



and again along the Hardy River, but more frequently 

 about the edges of the cultivated country in the 

 Mexican portion of the Imperial Valley. I often saw 

 the Roadrunners travelhng along the ramparts of the 

 irrigation canals. A breeding female was collected 

 near Laguna's camp on March 31, and a male on the 

 outskirts of Mexicali, April 19. 



70. Ceryle alcyon. Belted Kingfisher. — One seen at Vol- 



cano Lake, April 25. Rhoads saw the species fre- 

 quently in the delta. 



71. Dryobates scalaris lucasanus. San Lucas Wood- 



pecker. — A black and white woodpecker observed 

 several times along the eastern base of the Cocopahs 

 was doubtless the San Lucas Woodpecker, for Stone 

 identified Rhoads's four specimens as this subspecies. 



72. Centurus uropygialis. Gila Woodpecker. — Frequently 



seen between the Hardy and the Cocopahs. Rhoads 

 collected specimens which had been feeding on mistle- 

 toe berries. 



73. Phalsenoptilus nuttalli subsp. — Two large Caprimulgids 



seen just before dusk near our first night camp in the 

 Cahuilla Basin, March 29, were presumably some form 

 of Poor-will. 



74. Chordeiles acutipennis texensis. Texas Nighthawk. 



^My two skins, both breeding males, were collected 

 on the western slopes of Pattie Basin on April 6 and 12 

 respectively. In measurements the specimens are 

 somewhat intermediate between texensis and the more 

 southerly form inferior. Indeed, I believe that knowl- 

 edge of the locality in which the birds were taken 

 would be necessary to the systematist who might 

 hope to relegate them to their proper subspecies. 



Nighthawks were abundant throughout the entire 

 region visited, resting by day under the creosote 

 bushes, and coming forth by the thousand at about 

 the same moment just after sunset A curious point 

 that I noted about their flight was that the birds often
