and, lastly, though resident at Santa Paula, they are rare. I do not think 
there were more than a dozen pairs in the whole Santa Clara Valley.”

Oregon Ruffed Grouse. 
I have a set of six eggs of this species, collected in Coos county, Ore- — 
gon, April 28, 1880. Their color is a rich creamy-white, unspotted.- 
The nest was a hollow of the ground, made by the bird and lined with 
leaves ; it was situated partly under a fallen tree, and quite hidden by a 
growth of bushes. The inside diameter of the nest was about six inches, 
and the depth about four. The eggs exhibit the following dimensions:

Sage Cock. 
Mr. G.. G. Mead of Rawlins, Wyoming Territory, has given me 
a very lengthy and interesting life history of this bird, from which I 
compile the following: ‘‘ The Sage Cock, ‘Sage Grouse,’ or ‘Sage Hen,’ 
as it is commonly called inthe West, is principally found in what are known 
as the ‘Sage bush regions’ of the Territories of Wyoming, Montana, 
Idaho and Arizona. A few are still to be met with in Coloradu, Nevada, 
California and other Western States and Territories, where the march of 
civilization has not exterminated their favorite food, the leaves of the wild. 
‘Sage bush which, with a heavy growth, covers large tracts of Western 
country. This is the natural home of the bird. In size and carriage they 
strongly resemble the Wild Turkey, but their color is so near like that of 
the ground and sage bush that it is difficult to detect their presence. 
In summer their food is sage leaves, berries and insects, but their sole food 
in winter seems to be sage leaves. The male isa little larger than the 
female; their weight is about ten pounds, and that of the female seven, 
live weight. They roam everywhere in winter in large flocks, the snow 
quenching their thirst instead of the water in the streams which supply 
them in the summer and along which they scatter in small bands at this
