Family MIMIDJE.—SAGE THRASHER. 
702. Oreoscoptes montanus. 8 V 2 inches. 
Range. —From Lower California and Mexico on the plains to 
Montana. This is an abundant bird in the sage regions of the 
plains throughout its range, and are frequently called the 
Mockingbird, on account of the varied song which they give 
from the top of some sagebrush or cactus, in which they 
nest. Four eggs, greenish, spotted with brown (.60 x.55). 
Family CINCLID^. 
DIPPER, OR WATER OUZEL. 
701. Cinclus mexicanus unicolor. 8 inches. 
Range. —Mountains of western North America from Alaska 
to Mexico. Among the rapid streams that are falling down 
the mountain side, these gray birds are to be found. They 
are strange members of bird life; they do not have webbed 
feet, and yet they swim on, or under the water, using their 
wings as paddles. They have a thrush-like bill, the habit of 
teetering similar to the sandpiper, and a song that is not 
to be forgotten if once heard. They nest on the rocks of 
these rapid streams, making their nest of moss, a bulky affair 
with an opening in the side, in which they deposit their 
four or five eggs of pure white ( 1.00 x.70).
