None of these six specimens hadeaten grain, which usually enters into the blue jay*- food to someextent, and in certain localities in New Hampshire that came underdirect observation furnished a significant part of it. The blue jaytakes about three times as much vegetable as animal food. It appearsto do no harm at Marshall Hall and consumes a fair quantity of injuri-ous beetles, grasshoppers, and caterpillars. The common crow ((orvus americanus) was much more numerous onthe farm than the fish crow ((orvus ossifragus). Four stomachs of theformer species were collected. In the case of this bird, which, as hasbeen shown, attacks poultry and grain (see pp. i) and*).)), protection. ?^0m i is not desirable at Marshall Hall. Elsewhere the species may do asmuch good as harm, perhaps even more, but here local conditionsmake encouragement of its presence incompatible with prudent farming. ME ADO WL ARKS, BOBOLINKS, AND COWBIRDS. The meadowlark {SturneUa magna) is one of the class of highly use-ful birds. It is commonly supposed to be largely vegetarian, but itreally takes about three times as much animal matter as of this major part is usually composed of grasshoppers,though these insects were not abundant enough at Marshall Hall toenter largely into the food of the 7 meadowlarkscollected. Injuriousbeetles and caterpillars, however, were taken in customary meadowlark, which is commonly regarded as a game bird at 8PECIE8, 95 Marshall Hall, is frequently shot, and its valuable work as a destroyerof weed seed and insects is thus often cut off.
