. Farm friends and farm foes : a text-book of agricultural science . Agricultural pests; Beneficial insects; Insect pests. RELATIONS OF BIRDS TO ORCHARDS 287 sects, leaf hoppers, and many other true bugs suck out the sap; leaf miners of many sorts mine the leaves.; while beetles, grasshoppers, crickets, and numberless caterpillars devour the blades. Set over against these myriads of leaf-feeding insects, we find the great majority of our familiar birds. Watch the birds in an orchard on a summer day and you will be convinced of their great value as insect destroyers. If you are keen-eyed and patient, you will see the warblers and other smaller birds searching leaf after leaf for aphides and tiny caterpillars, while vireos, bluebirds, robins, thrushes, sparrows, cedar birds, cuckoos, catbirds, blackbirds, and others are devouring the larger en- emies. If you watch these birds at their nests, you will see that the young are fed with vast numbers of such insect foes. Even in winter the eggs and pupae are con- tinually eaten by birds. The enemies of the fruits of orchard trees are less numerous than those of the leaves, but still their name is legion. Scale insects, beetles, bugs, caterpillars, maggots, midges, and other pests all attack one kind of fruit or another, often destroying the bulk of the crop. The birds that attack these enemies are nearly as numerous as those that attack leaf-feeding insects, and the good they do is Tent-caterpillar Nest at- tacked BY Birds.
