They did this with many other birds who are said to do harm,—hawks, owls, blackbirds, kingbirds, and others. That is how we come to know what birds eat, and can tell whether they do harm or good. There can be no mistake in this way of knowing, and so what comes from this department may be relied upon as true.
I want this little book to help the bird-lovers in the South and West of our big country, as well as in the East; and so, in each Family, I shall try to tell about a bird who may be seen in each part. A good many of our birds are found both East and West, with slight differences, but some that are in one part are not in the other.

THE THRUSH FAMILY
(Turdidæ)[2]
This family is named after the thrushes, but our familiar robin belongs to it, and also the sweet-voiced bluebird. The birds of this family are all rather good sized, and excepting the bluebird show no bright colors. Nearly all of them have spotted breasts when young, and many of them keep the spots all their lives. Young robins and bluebirds have spots on breasts and shoulders, but when they get their grown-up plumage there are none to be seen.
The thrush family get around by hopping, and do not walk, though some of them run, as you have seen the robin do on the lawn. Most of them live in the woods, and feed on the ground, and all of them eat insects. Because their feeding grounds freeze up in winter, most of these birds go to a warmer climate, or migrate. They are all good singers, and some of them among the best in America.
