Grinnell, Summer Birds of Mount Pinos, Cal. ? 8 ~l 



species with two nearly full-grown young lived in the neighborhood of 

 Seymour Creek meadow, 5500 feet. Here they obtained an easy liveli- 

 hood from the swarms of grasshoppers. Besides these, the stomach of 

 one of the hawks shot, contained a nearly entire chipmunk (Eutamias 

 merriami). 



ii. Aquila chrysaetos (Linneeus). Golden Eagle. — A pair or more 

 were seen repeatedly about the summit of Mount Pinos. 



12. Falco mexicanus Scklegel. Prairie Falcon. — A single adult 

 male specimen of the Prairie Falcon was shot by Dixon on July 4 at 

 about 8000 feet elevation, among the Jeffrey pines. The stomach con- 

 tained portions of a young Mountain Quail. 



13. Falco sparverius Linnceus. American Sparrow Hawk. — Spar- 

 row Hawks were but sparingly represented in the region, and noted only 

 below 8000 feet. 



14. Nyctalops wilsonianus {Lesson). American Long-eared Owl. — 

 I shot an adult male Long-eared Owl below the Columbus Borax Mine, 

 5000 feet, in the evening of June 2$ Owls were apparently very scarce 

 in the Mount Pinos country. We heard them at night only in one place. 

 Seymour Canon. The notes were unfamiliar and we concluded they 

 might have emanated from a Spotted Owl. 



15. Dryobates villosus hyloscopus (Cabanis). Cabanis Woodpecker. 



— This woodpecker proved to be fairly common all over the mountain 

 above 6000 feet. Full-grown young were noted June 28. 



16. Dryobates nuttalli (Gambel). Nuttall Woodpecker. — A juve- 

 nile was secured in Seymour Canon at 6500 feet on July 13; and another 

 individual was heard on a subsequent day among golden oaks further 

 down, at about 5500 feet. 



17. Xenopicus albolarvatus gravirostris (Grinnell). Southern White- 

 headed Woodpecker. — The White-headed Woodpecker was moder- 

 ately common among the firs on the north side near the summit, while a 

 few were met with in the Jeffrey pine belt down to 6500 feet. Both adults 

 and young were secured. Dixon saw the species also on Frazier Moun- 

 tain, 15 miles east of Mount Pinos. The specimens secured average 

 nearest the large-billed race, gravirostris. The bills, however, which 

 furnish the main distinguishing character, are slightly smaller than in 

 the case of the San Gabriel birds. This lends evidence of intergradation 

 with albolarvatus. Hence I employ the trinomial form of name. 



18. Colaptes cafer collaris (Vigors). Red-shafted Flicker. — A 

 few flickers, some of them juveniles, were encountered in the Jeffrey pine 

 belt from 6500 feet to the summit. 



19. Phalaenoptilus nuttalli californicus Ridgxvay. Dusky Poor-will. 



— The mellow notes of the Poor-will were heard regularly morning and 

 evening in Seymour Canon, 6000-6500 feet ; and also one evening on 

 the very summit of Mount Pinos, 8826 feet. 



20. Aeronautes melanoleucus (Baird). White-throated Swift. — 

 On July 9 several White-throated Swifts were seen flying about the sum- 

 mit of Mount Pinos.
