Woodpeckers attack borers and bark insects ; creepers, nuthatches and titmice search out those insects peculiar to trunk and limbs; warblers and all the smaller birds assail insects injurious to foliage. Crows, robins, sparrows, woodcocks, sandpipers, meadowlarks and other ground - feeding species unearth insects in the fields; while all birds of the open take insects from the grass. Grasshoppers and caterpillars, the most conspicuous enemies of grasses and trees, respec- tively, form a staple food for nearly all land birds. Birds may be quite as serviceable to man in orchard and shade trees as in field or woodland, if they receive protection and are provided with safe nesting-places and sufficient shelter at all seasons ; but they are not ordinarily so useful in gardens and cultivated fields, for there they find no safe nesting-places, and the frequent operations of til- lage during the time when insects are most destruc- tive tend rather to drive them out. A few species, however (notably the robin, house wren, chipping sparrow, song sparrow and quail), are very destruc- tive to garden insects; while swallows, nighthawks and martins, which catch insects in the air, are serviceable about the garden and cultivated field. The hairy woodpecker, the downy woodpecker and their allies are among the most useful birds of woodland and orchard. These birds peck into the trees and abstract wood-boring ants, the larvae of wood-boring beetles and the hibernating larva? or pupa? of injurious moths. The downy woodpecker is par- ticularly destructive to the white pine weevil, the cod- ling-moth, the apple-tree borer, the woolly aphis and other enemies of the or- chard. These woodpeckers should not be confounded with the red-bellied sap- sucker, which is sometimes injurious to trees in the more northern parts of the United States. Warblers are insect-eaters chiefly
