California Clapper Rail 



Adult (sexes alike). — Clapper rails with the cheeks and auriculars 

 brownish, not grayish; breast light ochraceous-buff. Two phases, 

 according to the color of the edges of the feathers of the upperparts, 

 as follows: 



Brown phase : Forehead, crown, occiput, and hind neck Saccardo's 

 umber, the frontal and coronal feathers with shiny black shafts, 

 those of the hind neck with paler, tawny-olive edges; scapulars, 

 interscapulars, feathers of back, rump^ and the upper tail coverts 

 sepia very broadly margined with ashy buffy brown washed with 

 olive, the dark centers reduced to the vanishing point on the rump 

 and upper tail coverts; rectrices like the back, but the dark centers 

 verging indistinctly into the paler margins, not sharply distinct; 

 outer, upper, lesser, and median wing coverts sayal brown to tawny- 

 olive; inner ones olive buffy brown to sepia, paling to snuff brown on 

 the outer webs, the innermost secondaries like the long scapulars; 

 supraloral stripe pinkish buff washed with rusty; lores, cheeks, and 

 auriculars brownish drab; malar stripe light ochraceous-buff; chin 

 and upper throat white, sometimes faintly washed with buffy; sides 

 of neck, lower throat breast, and upper abdomen light ochraceous- 

 buff, becoming slightly darker and more ochraceous in the middle of 

 the breast, sides, and flanks; and vent grayish buffy brown barred 

 with white; lower abdomen whitish lightly washed with pale 

 ochraceous-buff; lateral under tail coverts largely white; the median 

 ones like the flanks ; under wing coverts slightly browner, more sepia, 

 than the flanks ; soft parts apparently unrecorded ( ! ) , but probably 

 as in the other races of the species.
