yO WxDMANN, Yosemite Valley Birds. \a^ 



30. Spizella socialis arizonae. Western Chipping Sparrow. — 

 Like the Robin, generally distributed and numerous. 



31. Junco hyemalis thurberi. Sierra Junco. — Very numerous; 

 always a few together, sometimes as many as 20 to 30 on the ground 

 feeding in openings and on meadows. 



32. Passerella iliaca megarhyncha. Thick-billed Fox Sparrow. — 

 Only once seen, Mny 21. 



33. Pipilo maculatus megalonyx. Spurred Towhee. — Apparently a 

 common breeder ; several males singing all day at their stands. 



34. Oreospiza chlorura. Green-tailed Towhee. — In 6 or 7 places, 

 a diligent musician whose song reminded me strongly of Chondestes 

 grammacus. 



35. Zamelodia melanocephala. Black-headed Grosbeak. — The 

 most prominent of all songsters in the valley, where at least fifty individ- 

 uals were present, and females as well as males everywhere in sight ; two 

 males found singing on nests less than eight feet from ground. 



36. Cyanospiza amcena. Lazuli Finch. — Three pairs were located; 

 song differed much individually ; one's song was remarkably like that of 

 the Indigo Bird, another's more like a Goldfinch's. 



37. Piranga ludoviciana. Western Tanager. — Quite abundant after 

 the 22d ; not only old males as before, but females and young of last year 

 of different patterns of coloration in small troops, singing and mating. 



38. Tachycineta lepida. Violet-green Swallow. — When after the 

 frosty mornings the sun began to warm the valley half a dozen swallows 

 were hunting over the meadow behind the village or resting on the fence 

 wires for an hour or two On the afternoon of the 24th a large number 

 of swallows was seen, perhaps fifteen hundred feet above the valley, 

 hunting on the sunny side between Union and Glacier Points. 



39. Stelgidopteryx serripennis. Rough-winged Swallow. — ^ Two 

 (probably a pair) hunting \\ith Tachycineta over meadow, May 22. 



40. Vireo gilvus swainsoni. Western Warbling Vireo. — One of 

 the common songsters, heard everywhere and often seen. 



41. Vireo solitarius cassini. Cassin Vireo. — Almost as numerous 

 as the Warbling Vireo and nearly as musical; their pleasing song one of 

 the common sounds in the valley and the musicians themselves easily 

 detected. 



42. Helminthophila rubricapilla gutturalis. Calaveras Warbler. — 

 With the Vireos and Yellow Waibler, one of the common songsters. 



43. Dendroica aestiva morcomi. Western Yellow Warbler. — 

 Generally distributed and an industrious songster. 



44. Dendroica auduboni. Audubon Warbler. — This is the only 

 warliler yet in troops of twenty and more, while single individuals and 

 pairs were scattered all over the valley. Two individuals were noticed 

 in which it required a good light to discover yellow traces on the white 

 throat, and thus could easily have been mistaken for D. coronata. 



45. Dendroica nigrescens. Black-throated Gray Warbler. —
