Bird Houses and How to Build Them

Bird Houses and How to Build Them

Date: 1914
Creator: Dearborn, Ned, 1865-
Description: "A few years ago only four species were commonly regarded as house birds -- the house wren, the bluebird, the tree swallow, and the martin. Since the movement to protect birds and make neighbors of them began, however, their natures and needs have become better understood, and it is now known that many other species will avail themselves of houses constructed for them by their human friends. The practice of erecting bird houses in this country, while now nation-wide, is not so common and uniformly distributed as it should be, and more extended provisions of this nature can not fail to result in a largely increased number of house birds." -- p. 2
