Taken at the Cottonwood Lakes, alt. 11,000 Photo by the Author SUNRISE IN THE SIERRAS gray; lateral crown-stripes rich brown (dark mars brown or dark chestnut), the in- cluded area buffy brown; streaks of back darker; and wings with slight increase of whitish edgings. Young birds are recognizably similar to immatures, but the crown- stripes are broader, grayish brown spotted with black, and the whitish underparts are sharply streaked with dusky.

Eggs: 3 to 5; pale bluish green (lichen green to palest niagara green), moderately or heavily sprinkled and spotted, or, rarely, mottled with brown (verona brown, or Rood's brown, or mars brown); markings show tendency to form cloud-cap or, more rarely, cumulus; ground-color sometimes practically buried under pigment. 42 Sierra-taken eggs in M. C. 0. collection show limits of x (. by .) and average x (.84 x .65). Season: Ma}' 20-July 20; one or two broods.
