The rose-breasted grosbeak, while it eats a few green peas, is to be classed among the wholly beneficial birds, for it is the great natural destroyer of the Colorado potato beetle. In fact, it eats enough potato-bugs at a single meal to pay for all the peas eaten in a whole season. One family of grosbeaks, nesting near the field, will keep an entire patch cleared of potato-bugs throughout the season. In some parts of the country the grosbeak feeds largely on the plum scale, the hickory scale, the locust and oak scales and on the tulip scale, which is very destructive to shade trees. The black grosbeak is another variety that deserves encouragement in every way, for it eats the chrysalis of the codling-moth that is so serious a foe to our apple crop. It eats also many other injurious insects, such as wire-worms, many of the most harmful of beetles, caterpillars, and scales. Among the most useful birds, we must mention the phoebe, which nests near houses and lives almost entirely on harmful insects which it catches on the wing. Night hawks eat flying ants in great numbers, as many as eighteen hundred having been found in a single stomach. They eat insects that fly by night and are classed among our most useful birds. Quails are almost unequalled as weed-destroyers. Throughout the fall and winter they spend the time destroying weed seeds. In summer they eat Colorado potato beetles, chinch-bugs, cotton boll-weevils, squash-beetles, grasshoppers and cutworms. The mother quail, with her family of twelve to twenty little ones, patrols the fields thoroughly for insects. Quails should be prized as among a farmer's most valuable helpers and protected at all seasons. Similar in the good work it does is the meadow-lark. Grasshoppers, caterpillars and cutworms form a large part of its diet, and its vegetable food consists of weed seeds or waste grain. King-birds are useful in protecting poultry and song birds from hawks, and are also great fly catchers, taking many beetles on the wing. Doves eat great quantities of seeds of harmful weeds. They also eat some grain, but almost altogether after the crop has been gathered. Old damaged corn and single grains scattered along the roads are eaten, but there is no complaint of doves doing injury to fields of growing grain. The orioles are beautiful, are sweet singers, and no exception can be taken to their food habits. Caterpillars are their principal article of food, but plant-and bark-lice, spiders and other insects are also eaten. Orioles do not eat much vegetable food. They have been accused of eating peas and grapes, but there seems no evidence to show that this habit is general.
