The bird seemed to know the exact spot at which to drill for each larva, for it always cut a small hole directly over the insect. The cut (Fig. Ill) gives a view of the outer surface of a section of bark taken from a small oak. From this small piece of bark the bird probably se- cured at least six of the larvae that were found in its stomach. The holes at a, b, c, d, e, f, indicate those from which the larvae were taken. Fig. 112 gives a view of the inner surface of the same piece f"--JlW Hl'lilH"""" of bark, showing how true was the stroke of the bird, for its beak, piercing from the outside, went di- rectly to the cen- ter of the burrow where the dormant insects lay, entirely hidden from view. The letters a, b, c, d, e, f, indicate the holes where the bird's beak came through to the inner surface. Twelve ants and seventeen larvse of boring beetles were found in its stomach. The Downy Woodpecker is one of the most useful of all birds to the lumberman, for it feeds on such destructive insects as the bronze birch borer, the maple borer, and the pine weevil,—an insect of such importance that its habits merit some description here. This little insect (Pissodes strobi) deposits its eggs on the topmost shoots of the finest and most vigorous young white pines, and the young larvae.
