British Columbia to Lower California and southern Arizona, and from

compact, cup-shaped, like that of D. cestiva , made of gray plant fibers, 
lined with feathers. Eggs: 3 or 4, white, tinged with pink or cream,

The quiet little black-throated gray warbler is a restful contrast to 
the whirligig of perpetual motion, the omnipresent Audubon warbler 
of the Sierra Nevada. It seems to be especially a bird of Transition 
low growth, such as scrub oaks, pinons, junipers, and manzanitas. 
Along the North Fork of the Yuba River in the Sierra we found 
it singing in the bushes along the road, and in the junipers on a 
hillside near camp. Its song is a simple warbler lay, zee-ee-zee-ee, 
ze, ze , ze, with the quiet woodsy quality of virens and ccerulescens, 
so soothing to the ear.
