308 CALIFORNIA BIRD STUDIES 



Ruby-crowned Kinglets, the most gifted of small feathered 

 vocalists ; trilling Jmieos, Calaveras, .Audubon's, Pileolated, 

 and Macgillivray's Warblers were the birds whose voices 

 were most prominent! 



Several times I saw Solitaires perched silent and pen- 

 sive, and about the falls in the Glen, active Water Ousels 

 were sometimes seen, but their song season was over. 



A nest of Blue Grouse, {Dendragapus fuliginosus sier- 

 ra), with broken egg-shells, from which the chicks had only 

 recently emerged, was found, dune 30, well up the Glen and, 

 on one occasion, a bird of this sjiecies was heard to utter its 

 hollow, ventrilocpvial boom. 



Blue-fronted days were among the common forest birds 

 and occasionally Clarke's Crows crossed the Glen from 

 tree-top to tree-top to disappear up the mountain side. 



The Woodpeckers of this region are of great interest 

 and will afford the eastern ornithologist some brand new 

 sensations in bird-life. In addition to the Red-shafted 

 Flicker and the western form of the Hairy Woodpecker, I 

 observed the blackbird-like Lewis's Woodpecker in the 

 woods about Tallac. More generally distributed were the 

 quaintlj r plumaged White-headed Woodpecker, and the Red- 

 breasted Sapsueker, while, on the surrounding mountains, 

 the beautiful Williamson's Sapsueker was not uncommon, a 

 nest, containing young, being found in a dead tree on duly 2. 



All the species mentioned were seen between June 24 and 

 July 5, 1903. When I visited the camp from June 8 to 10, 

 1906, the Glen had not yet shaken off the grip of winter. 

 Snow-slides, ten feet deep, blocked the trail and along their 

 edges, snow-flowers, like little torches, blossomed. The wil- 

 lows and alders were blooming, White-crowned and Fox 

 Sparrows, Olive-sided Flycatchers, Mountain Quail and 

 Chickadees, were singing, but the Warblers had not yet 

 come up from the lower altitudes. 



On June 30, I crossed the mountains on horseback at 

 Angora Lake and struck the Tahoe-Placerville staa'e-route
