APPENDIX 



Head plume long and slender. Length, eleven and a half inches. 

 Head lead colored; back olive-brown; throat chestnut, bordered by a 

 line of white; breast lead colored or slaty bluish; sides chestnut, barred 

 with conspicuous markings of black and white. The mountain-partridge, 

 strictly speaking, inhabits the mountains to the north of California, but a 

 race form, differing chiefly in a more grayish olive tone to the back and 

 in a few other minor points, breeds throughout the Sierra Nevada 

 Mountains and winters in the foothills and Coast Range. Although 

 known in the books as the plumed partridge, it is everywhere popularly 

 called the mountain-quail. 



2. California Partridge; "Valley-Quail"; Lophortyx calif ornicus 

 (Shaw). 



Head plume erect or thrown forward; composed of wedge-shaped 

 feathers. Length ten and a half inches. Upper parts olive-brown and 

 gray; the forehead pale buffy or whitish, finely lined with black; top of 

 head brown bordered with black; throat black bordered with while; 

 breast plumbeous, changing below to bufly or whitish, where the feathers 

 are bordered with dark brown, giving the belly a scaled effect, and with 

 a central chestnut patch on belly ; sides olive-brown, with narrow streaks 

 of white. The female is similar, but lacks the black, white and chestnut, 

 making it much duller and more monotonous in color. 



This variety of the valley-quail is found in the coast valleys of the 

 northwest coast of California and northward. In central and southern 

 California a slightly paler form, the valley-quail proper, is found in 

 the valleys and foothills both of the coast and interior. 



3. Gambel's Partridge; Lophortyx gambelii (Gambel). 



Length a trifle less than the preceding, which it resembles in general 

 appearance. The top of the head is bright rufous, the belly is black 

 centered instead of chestnut, surrounded by a broad patch of pale buffy, 

 and the sides are chestnut with streaks of white instead of olive-brown, 

 as in the preceding. A desert form occurring in California only on the 

 Mojave and Colorado Deserts. 



4. Sooty Grouse; Pine-Grouse; Dendragapus obscurus fuligin- 

 osus Ridgw. 



The only scratching bird of California which habitually frequents 

 high trees. Length nearly two feet. General color blackish brown 

 mottled with rusty; on breast mottled slaty gray; cheeks black; throat 

 white, mottled; tail blackish with broad gray band at the tip. An 

 inhabitant of the pine woods of the Coast Range and the Sierra Nevada 

 Mountains. 



5. Oregon Ruffed Grouse; Bonasa umbellus sabini (Dougl.). 

 Distinguished by broad tufts of soft, glossy, brownish-black feathers
