This Wren has justly been called a perennial songster. "In Spring the love-song of the Wren sounds through the forest glades and hedges, as the buds are expanding into foliage and his mate is seeking a site for a cave-like home. And what a series of jerks it is composed of, and how abruptly he finishes his song, as if suddenly alarmed; but this is his peculiar habit and common to him alone. In summer we hear his song morning, noon, and night, go forth for very joyfulness, as he wanders hither and thither in his leafy bower." It is only in the moulting season that he does not sing. A lady who used to attract a great number of birds to her garden with crumbs, seeds, and other dainties, said that when the weather became cold the Wrens used to gather upon a large branch of a tree, about four inches beneath another branch. They assembled there in the evening and packed themselves very comfortably for the night, three or four deep, apparently for the sake of warmth, the topmost Wren always having his back pressed against the outer branch as if to keep all steady. Pitying their forlorn condition, she provided a bedroom for them--a square box lined with flannel, and with a very small round hole for a door. This was fastened to the branch, and the birds promptly took possession of it, their numbers increasing nightly, until at least forty Wrens crowded into the box which did not seem to afford room for half the number. When thus assembled they became so drowsy as to permit themselves to be gently handled. [Illustration: From col. Chi. Acad. Sciences. LONG-BILLED MARSH WREN.] THE MARSH WRENS. A happier pair of birds than these little Wrens it would be hard to find. They have just come up from taking their morning bath and are going to sing a while before going to work on their nests. You see I say nests. That is a strange thing about the Wrens, they build several nests. I wonder if you can tell why they do this. If you can't, ask your teacher about it. It is a little too early in the season or I would have one of the nests in the picture for you to look at. I will try to describe it to you, so that you will know it when you see it. These little Wrens make their nests of coarse grasses, reed stalks, and such things, lined with fine grasses. It is round like a ball, or nearly so, and has the opening in the side. They fasten them to the reeds and bushes. If you wish to get acquainted with these birds, you must visit the tall grasses and cat-tails along rivers and creeks and in marshes. You won't have to let them know that you are coming; they will see you long before you see them, and from their little nests they will begin to scold you, for fear that you mean to do them harm. When they see that you mean them no harm, they will begin to entertain you with their songs. Oh, how they do sing! It just seems as though they would burst with song.
