Food habits of the grosbeaks

Two distinct groups of finches or sparrows are commonly known as grosbeaks. One of these, which includes the pine and evening grosbeaks, is of little practical importance, since its members breed and pass most of their lives in mountainous regions, or in the northern parts of North America. The other group includes the cardinal, gray, rose-breasted, black-headed, and blue grosbeaks, which spend either the summer or the entire year within agricultural regions of the United States. Hence their food habits are of considerable importance to the farmer.
