UPLAND GAME BIRDS W7 



Nest : On ground in the woods, nsually under fallen trees. 

 Eggs : 6 to 12 ; buffy, sometimes slightly stained or speckled with brown. 

 Size 1.56 X 1.16. 



This is a fairly common resident, in the coast district 

 of Northern California. Its habits of " drumming," etc. 

 are like those of the Eastern grouse. The cocks leave 

 their mates as soon as sitting begins, and do not usually 

 return until fall, when the broods get together for the 

 winter. The young are to be found with the mother in 

 the vicinity of the nesting place for ten days or two 

 weeks, and then are taken to a thicket-bordered stream. 

 Their food consists of grasshoppers, insects, young leaves 

 of plants, berries, and a few varieties of seed, such as the 

 wild sunflower.
