THE BIRD'S HOME
Each bird mother has her own way of making the nest, but there is one thing almost all of them try to do, and that is to hide it.
They cannot put their little homes out in plain sight, as we do our houses, because so many creatures want to rob them. Squirrels and snakes and rats, and some big birds, and cats and many others, like to eat eggs and young birds.
So most birds try, first of all, to find good hiding-places. Some tiny warblers go to the tops of the tallest trees, and hide the nest among the leaves. Orioles hang the swinging cradle at the end of a branch, where cats and snakes and naughty boys cannot come. Song sparrows tuck the little home in a tuft of weeds, on the ground, and bobolinks hide it in the deep grass.
After a safe place is found, they have to get something to build of. They hunt all about and gather small twigs, or grass stems, or fine rootlets, and pull narrow strips of bark off the grapevines and the birch-trees, or they pick up strings and horsehairs, and many other things. Robins and swallows use mud.
