Bird Houses Boys Can Build

Excerpt

Certain varieties of birds will nest in homes built for them if these houses are of the right shape and dimensions. Other birds may be just as desirable but do not build nests and rear their young in boy-made nesting boxes. We are therefore mainly concerned with the first group which select cavities in trees for their homes if nothing better is to be found.

FIG. 1. BLUE BIRDS, ADULTS AND YOUNG BIRD.

This bird may be found during the summer months in most of the states east of the Rocky Mountains, Figs. and . It spends its winter in the southern states and southward, returning north in March and April. The principal items of food are grasshoppers, caterpillars and beetles. It should have a house measuring about 5" in length and width, inside measurements, and 8" or more in depth. The entrance hole should be 1-1/2" in diameter and placed near the top, so that the young birds cannot get out until strong enough to have some chance of escape from their enemies after they leave the nest. While authorities differ as to the need of cleaning after a season's use, it seems wise to provide the house with some device whereby the bottom may be removed for such purposes. Houses for this species are shown in Figs. , , and .

FIG. 2.

Robins usually announce the coming of spring when they return to their breeding grounds in the northern states, where they are general favorites. Figs. and . The nest is usually built of mud and lined with grasses; placed in the fork of a tree or on some sheltered ledge. Robins take kindly to nesting shelves put up for them and it is well to put up several since but one brood is reared in each nest built. This old nest should be removed after the young birds have gone. A simple shelf is shown in the lower left hand corner of the photograph, Fig. , as well as in Figs. and .

FIG. 3.

The chickadee is one of the brave little spirits who spends the entire winter with us, Fig. . We can be of considerable service to him during the cold weather by providing food shelters. During the summer months his home is usually found in some decaying stump, hence nesting boxes of the rustic type placed in some remote spot of the orchard or park are most attractive to him.

When all other song birds fail to take advantage of a house built for them, the wren may still be counted on. Almost any sort of home from a tin can or hollow gourd on up is satisfactory if put in a safe place and provided with an opening 1" or slightly less in diameter, so the sparrows must stay out, Figs. and . Good homes are shown in Figs. , , , and others.

FIG. 4. WREN AND RUSTIC HOUSE.

The house finch has made many enemies because of its fondness for cultivated fruits and berries. However, it has some redeeming features in its song and beauty. The nest is usually placed in the fork of a limb—evergreens being favorite nesting places. The house shown in Fig. is suitable for these birds but is also acceptable to wrens.

FIG. 6. FLICKER.

The favorite of this interesting family is the little downy, Fig. . Living largely upon harmful grubs and insects, this bird does an immense amount of good by protecting our forests from insect scourges. Woodpeckers do not build nests as most birds do, but excavate a deep cavity in some dead tree leaving a quantity of chips at the bottom on which the eggs are laid....
