86 Vol. XX SEVEN NEW OR NOTEWORTHY BIRDS FROM EAST-CENTRAL CALIFORNIA By JOSEPH GRINNELL (Contribution from the Museum of Vertebrate Zoology of the Ufiiversity of California) HE FIELD WORK carried on by the California Museum of Vertebrate ' Zoology during 1917, in that portion of California comprising Mono and Inyo counties, brought to light some new facts in regard to the general dis- tribution and geographic variation of western birds. The more prominent of these discoveries are set forth in the present paper, .whereby seven new names are added to the list of the birds known to belong to California. Glaucidium gnoma pinicola Nelson Rocky Mountain Pigmy Owl An adult female of this owl (no. 27887, Mus. Vert. Zool.) was taken by the writer September 30, 1917, at 6200 feet altitude some three miles east of Jackass Spring, in the northern section of the Panamint Mountains, Inyo CSunty. The place of capture was in the pinyon belt, and here the species must have been com- mon, for the characteristic notes were heard almost nightly during the period from September 30 to October 7. The specimen shows nearly complete fresh plumage. As compared with ex- amples of Glaucidium gnoma californicum, in the same condition, from the Sierra Nevada, it is of slightly greater size, slatier (hair brown) tone of coloration on the dorsal surface, and has the streaking beneath blacker. Chord of wing, 101.1 mm.; tail (measured by the Ridgway method), 72.1; culmen from cere, 12.0. The features given acc6rd almost exactly with the characterization of pinicola fur-? nished by Ridgway (Birds N. and Mid. Amer., pt. % 1914, p. 789). Further- more, Mr. E. W. Nelson, the original describer of pinicola, who was recently shown the skin offhand without his previous knowledge of its locality, instantly pronounced it to belong to pinicola. Dryobates viiloans leucothorectis Oberholser White-breasted Woodpecker This proved to be the representative race Of the Hairy Woodpecker in the White and Panamint mountains, in Mono and Inyo counties. As compared with Dryobates villosus hyloscopus, of the southern Sierras and southern California generally, the Inyo birds are notably whiter beneath and smaller billed. As com- pared with D. v. orius of northeastern California the Inyo birds are decidedly smaller throughout. The following table serves to show the localities and meas- urements of the specimens of D. v. leucothorectis taken. _ .. Exposed NO. Sex Locality Collector Date Wing Ta? culmen 27892 ?
