282 ViSHER, Birds of Pima County, Arizona. [july 



29. Geococcyx californicus. Road-runner. — Abundant below 4000 

 feet most of the year. They have been seen leaving the nest of Gambel's 

 Quails carrying an egg in their beak. 



30. Coccyzus americanus occidentalis. California Cuckoo.* — A 

 common nester in the mesquite of the Santa Cruz bottoms near Tucson, 

 arriving the second week of June and leaving early in September. Their 

 call is feeble and resembles that of the Black-billed rather than that of the 

 more closely related Yellow-billed Cuckoo. One was seen carrying a yovmg 

 lizard. 



31. Dryobates arizonse. Arizona Woodpecker.*** — Breeds com- 

 monly in the oak zone. Nests found by Lusk. 



32. Xenopicus albolarvatus. White-headed Woodpecker.**** — 

 One seen at 7000 feet in the Catalinas May 26. I believe that this bird has 

 not been hitherto recorded from Arizona. Although I did not secure it, 

 identification could scarcely be doubtful. 



33. Sphyrapicus thyroideus. William.son's S.^.psucker. — A nest with 

 young found May 25 in the oak zone of the Catalinas. 



34. Antrostomus vocif ems macromystax. Stephens's Whip-poor-will. 

 — A conspicuous summer resident in the pine zone of the mountains. 



35. Phalsenoptilus nuttalli nitidus. Frosted Poor-will.** — While 

 nuttalli breeds only in the mountains, this variety is abundant throughout 

 the summer in the valley. Specimens of both have been taken by Lusk. 



36. Chordeiles acutipennis texensis. Texan Nighth.iwk.*** — An 

 abundant summer resident in the Lower Sonoran Zone — the valley. 

 Flight is low, almost always within twenty feet of the ground. The only 

 call, soft and bubbling, is heard at dusk only in the early summer. 



37. Aeronautes melanoleucus. White-throated Swift.*** — Nests 

 abundantly about the clitfs in the mountains. A few feed in the valley. 



38. Eugenes fulgens. Rivoli Hummingbird.** — Tolerably common 

 breeder above 6000 feet in the Catalina. (Lusk.) 



39. Archilochus alexandri. Black-chinned Hummingbird.* — The 

 only common hummer in March and April. Apparently winters in the 

 lowlands. 



40. Calypte costae. Costa's Hummingbird.* — The abundant sum- 

 mer hummer of the town of Tucson is Costa's. 



41. Selasphorus platycercus. Broad-tailed Hummingbird.— Mr. 

 Lusk says that this is the most numerous himimer breeding in the Catalinas. 



42. Selasphorus nifus. Rtrrous Hummingbird. — Lusk believes tliis 

 species does not nest in the Catalinas. 



43. Stellula calliope. Calliope Hummingbird. — Common migrant 

 at 7500 feet. (Lusk.) 



44. Cynanthus latirostris. Broad-billed Hummingbird.* — This 

 beauty was breeding abundantly at 3500 feet in Sabino Canon, in the 

 Catalinas, early in May. Mr. Lusk says they rear another brood in July 

 and August above 7000 feet.
