Book excerpt: Excerpt from Birds of America, Vol. 1 To the technical descriptive matter of especial interest to the systematic ornithologist, and the popular characterizations intended particularly for the non-scientific student Of birds, has been added wherever it is called for much very important and interesting matter concerning the actual usefulness of birds. This subject of economic ornithology has been carefully investigated by the United States Bureau Of Biological Survey, whose experts have gathered and compiled a great mass of statistics and other data concerning the food habits of birds, the object being to convey precise information as to which are the useful and which are the harmful species. It would be difficult to overstate the value of this work if its results were generally understood, for these researches demonstrate beyond peradventure the enormous usefulness of the birds in destroying insect pests which, but for this check of their natural rate of increase, would ruin every year many millions of dollars worth of crops, and threaten with defoliation and death many kinds of trees.
