SPRAGUE PIPIT. 700. Anthus spraguei. 6½ inches.
Range.—Breeds from Manitoba to Montana and Dakota, and west to the Rockies. Habits, nest and eggs are similar to preceding.
Family MIMIDÆ.—SAGE THRASHER. 702. Oreoscoptes montanus. 8½ 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 × .55).
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 × .70).
WESTERN MOCKINGBIRD 703a. Mimus polyglottos leucopterus. 10 inches.
Range.—Texas to California and southward, breeding commonly from central California southward. These birds not only have a song of their own which puts them in the opera class, but, as their name implies, they can mimic or mock nearly anything in the bird line for song or bird notes. They are not satisfied with a few notes early in the morning and evening, but will keep their song in full play all day, without hardly seeming to take time to hunt up a few worms or insects, as if eating was not to be considered when he could sing.
They nest usually low down in bushes and thickets, and construct a bulky nest of sticks, roots and grass. Three to five eggs are of a greenish color, spotted and blotched all over in many patterns with shades of brown (.95 × .72).
CATBIRD. 704. Dumetella carolinensis. 9 inches.
Range.—Mostly eastern North America, but extends over the Rockies, occasionally to the Pacific coast. It is a fine songster and almost as much of a mimic as the Mockingbird. Breeding habits are much the same, but eggs are bluish green (.95 × .70).
