Michigan bird life : a list of all the bird species known to occur in the State together with an outline of their classification and an account of the life history of each species, with special reference to its relation to agriculture ... .

LAND BIRDS. 459 the birds pull up sprouting grain, either corn, wheat or oats, and theyalso pick up any grain left uncovered; but it is during the harvest season,and especially during the time when corn is in the milk, that their attacksare most important. These facts show conclusively that the Crow Black-bird or Bronzed Grackle is a serious foe to the farmer whenever it occursin large numbers. Many instances are on record of flocks numberingthousands, or even tens of thousands, which have visited cornfields andgrain fields, doing a vast amount of damage in a short time. The Grackle also eats considerable quantities of fruit at certain times,the figures furnished by stomach examinations being 13 percent in Juneand 10 percent in July. The fruits most commonly attacked are rasp-berries, blackberries, cherries, and mulberries, but ordinarily no greatdamage is done.
