As winter approaches these snowbirds become more plentiful, hopping about in the small bushes in quest of food. A great deal of pleasure and interest may be found in studying these birds, especially when the ground is covered with snow. By casting bread crumbs on the snow, the little fellows flock around, and are easily tamed. In winter their only note is a sort of chirp, sometimes uttered several times in quick succession when alarmed. With the warm days of spring they begin their song, sometimes many singing at once, and soon the majority disappear to a higher altitude to breed. The Oregon Junco builds its nest in hollows in the ground under low bushes. The nest is constructed flush with the surface and in holes among the roots of bushes and trees, and under woodpiles. Usually, the nest is made of dry grasses rather loosely placed together, with a lining of cowhair, and contains four and sometimes five handsome greenish-white eggs, spotted and wreathed with purple.--J. Mayne Baltimore. * * * * * Olive Thorne Miller, in her fascinating little book, "The First Book of Birds," speaking of how the birds work for us, says: "Chickadees like to eat the eggs of cankerworms; and for a single meal one of these tiny birds will eat two hundred and fifty eggs, and he will take several meals a day. Now, cankerworms destroy our apples. When they get into an orchard in force, it looks, as Miss Merriam says, as if it had been burned over. Robins, cat-birds, and shrikes, and several others, like to eat cutworms, which destroy grass and other plants. As many as three hundred of them have been found in the stomach of a robin, of course for one meal. Ants are very troublesome in many ways, and three thousand of them have been taken from the stomach of one flicker." Why kill these birds that are so useful to us and so beautify nature? Many others are just as useful and some that occasionally do damage amply repay us in other ways. [Illustration: THE CALICO BASS. (Pomoxys sparoides.) COPYRIGHT 1900, BY A. W. MUMFORD, CHICAGO.] THE CALICO BASS. The Calico Bass (Pomoxys sparoides) is so called because of the mottled and variegated coloring of the body and fins. It is also called the Strawberry Bass, the Grass Bass, the Bitter Head, the Lamp-lighter and the Barfish. It is abundant in all the lakes and ponds of the region of the Great Lakes and the upper Mississippi river, where it shows a preference for quiet, cool and clear water and grass covered bottoms. The Calico Bass is closely related to the Crappie (Pomoxys annularis) of the lower Mississippi valley. It is, however, seldom seen where the Crappie is abundant, as the latter prefers muddy sloughs and bayous and is not found as far north as the former.
