Experience has shown that they may be prevented from pulling up young corn by tarring the seed, which not only saves the corn but forces them to turn their at- tention to insects. May beetles, " dor- bugs," or June bugs, and others of the same family constitute the princi- pal food during spring and early sum- mer, and are fed to the young in immense quantities. Ricebird.—The annual loss to rice growers on account of bobolinks has been estimated at §2,000,000. Meadow Lark. — Next to grasshop- pers, beetles make up the most impor- tant item of the meadow lark's food, amounting to nearly 21 per cent. May is the month when the dreaded cut'^worm begins its deadly career, and then the lark does some of its best work. Most of these caterpillars are ground feeders, and are overlooked by birds which habitually frequent trees, but the meadow lark finds and devours them by thousands. Sparrows. — Examination of many stomachs shows that in winter the tree sparrow feeds entirely upon seeds of weeds. Probably each bird consumes about one fourth of an ounce a day. Farther south the tree sparrow is replaced in winter by the white-throated sparrow, the white-crowned sparrow, the fox spar- row, the song sparrow, the field sparrow, and several others; so that all over the land a vast number of these seed eaters are at.
