THE Calaveras Warbler may be said to correspond to 
the Nashville warbler of the Eastern States. In Cali- 
fornia it is a haunter of the brush-covered hillsides, hid- 
ing shyly in the scrubby undergrowth and singing from 
the concealment of the deer brush and chaparral. Mr. 
Chester A. Barlow writes briefly in “The Condor,” 
November, 1901, of its occurrence in the Sierra Nevada: 
“ Although the species is far from rare in numbers, it 
appears that but comparatively few of its nests have 
been taken; but this is not strange when we consider 
the nature and extent of the country selected for nesting 
sites. It is usually by the merest chance that a nest is 
discovered, as successful a method as any being to beat 
through the ‘ mountain misery’ in the vicinity of where 
the male bird is found singing. On June 9, 1899, I 
flushed a Calaveras Warbler from her nest in tarweed 
beneath a small cedar at Fyffe, California, at which date 
the nest held five half-grown young. On June 10, 1901, 
at Slippery Ford, California, a nest was found built 
among an accumulation of dry black oak leaves beneath 
a deer brush on the side of a gulch. It contained five 
eggs, two-thirds advanced in incubation.”
