Bird Houses, Baths and Feeding Shelters: How to Make and Where to Place Them

by Edmund J. Sawyer

[Plate III] illustrates a wren house and gives directions for building. Distance from the ground to the entrance of the house should be from 8 to 18 feet. The place safest from cats is on the side of a building. If the box is on a tree or wooden post, protection is afforded by a band of smooth sheet metal such as zinc, 2½ feet high, starting not less than 4 feet from the ground or other point that is within reach of cats.

Two or three wren houses spaced as far apart as the yard or garden allows will provide for the duplicate, unused, nests which these birds often build, or for a possible second brood.

Other Wrens

For the Bewick’s Wren, which commonly nests around gardens, barns, and dwellings, the building directions are the same as for the House Wren.

The Carolina Wren of the south, more inclined to seek woods and thickets than to court man’s society, is not ordinarily a bird house tenant. Still, a home like that described for the House Wren, but with the entrance having a diameter of 1¼ inch, is not unlikely to be selected by the Carolina if placed in a brushy area frequented by him and not much frequented by humans.

The Black-capped Chickadee

Lacking the semi-domestic status of wren and martin, the Black-capped Chickadee is not a regular bird-house addict. He prefers the seclusion of some unfrequented wood. Yet, not uncommonly, he is enticed by a bird house. The specifications and illustrations for the wren house will do for the chickadee. However, a cylindrical and smaller chamber with somewhat larger entrance (1⅛ inch) is more likely to appeal to his uneducated taste. He is still a bird “with the bark on,” and his house should be quite literally in keeping. The author personally much prefers to select a hollow branch, from which he cuts a foot-long section. He then drills an entrance hole near one end, nails a piece of slab in place for the bottom, provides a removable lid of the same material, and thus constitutes himself a proxy for the Downy Woodpecker in providing the chickadee with a home. (See [Plate II].)
