It is no hardship for a woodpecker to make its own nesting ca\ity, and ])erhaps it is wiser to allow them to build their own cavity than to provide it for them. A few general rules should j^oxcrn tlie making;" and placinj^ (jf bird-houses. For Bluel)irds, Chickadees, House Wrens, and other species, old nesting cavities of Downy. Hairy or Red-headed Wood- peckers, with a rain-proof roof and securely fastened to a tree or post, will often be successful. A section of tree trunk sawed lengthwise, hollowed out, drilled with i)roi)er entr^uice hole, and then fitted together securely and placed in a suitable situation will admirably meet the needs of wood- peckers, Bluebirds and other species which use cavities. All boxes should be roofed carefully to prevent the entering of rain, and if possil)le the edges of the roof should protrude as eaves, under which ventilating holes should be drilled to make the nest cooler in summer. The interior of boxes should not be ])laned off, but sIkjuM be roughened so as to allow the young birds to clamber about with ease. For Bluebirds, House Wrens, and others it may be wiser to j)lace the box on a ])ole or iron ])ipe in the ojien in a more or less sheltered place rather than on a tree trunk; but in any event a belt of tin should be ])laced about the post or trunk to prevent cats from climbing uj). This tin should be wide enough and at a sufficient distance from the ground to i)re\ent cats from reaching or jumping over it. If many bird-houses are to be erected care should be used not to I)Iace them too near each other, since this will keep some birds from using the boxes, or will cause altercations of one sort or another during the nesting season. Although houses of one kind or another have been used and may be selected by many species of birds for nesting sites, the species listed below
