The long, slender boughs of the willow are the favorite resort of the oriole; and here, in the midst of a storm, the bird may sit in its swinging nest, fearing no danger. What is there to dread? The trees rock in the wind, but the oriole’s habitation is strong and well secured. Unless the branch from which the nest hangs be torn from the tree, the nest will endure the tempest and prove a safe shelter for the blithe little bird.
Many weaver-birds in Asia and Africa hang their nests from the ends of twigs and branches overhanging the water. This is to keep away monkeys and snakes, which abound in hot countries and are the greatest enemies birds have. The wise little weaver knows that the cunning monkey will not trust his precious life to a frail branch that may break, and drop him into the water; yet the same frail branch is strong enough for the bird and its nest. In this case, the monkey is obliged to admit that the bird’s wisdom is more than a match for his.
A very curious custom exists among a class of birds found in Africa, called “the social weavers.” They begin their work in companies, and build immense canopies, like umbrellas, in the tops of trees. These grassy structures are so closely woven that the rain cannot penetrate them. Under this shelter the birds build their nests, but no longer in company; the nest for each pair must be made by the pair without assistance from their neighbors.
The tailor-bird of India makes a still more curious nest than that of the weavers: it actually sews, using its long, slender bill as a needle. Birds that fly, birds that run, birds that swim, and birds that sing are by no means rare; but birds that sew seem like the wonderful birds in the fairy-tales.
Yet they really exist, and make their odd nests with great care and skill. They pick out a leaf large enough for their nest, and pierce rows of holes along the edges with their sharp bill; then, with the fibres of a plant or long threads of grass, they sew the leaf up into a bag. Sometimes it is necessary to sew two leaves together, that the space within may be large enough.
This kind of sewing resembles shoemakers’ or saddlers’ work; but, the leaf being like fine cloth and not like leather, perhaps the name “tailor-bird” is the most appropriate for the little worker. The bag is lined with soft, downy material, and in this the tiny eggs are laid—tiny indeed, for the tailor-bird is no larger than the humming-bird. The weight of the little creature does not even draw down the nest, and the leaf in which the eggs or young birds are hidden looks like the other leaves on the trees; so that there is nothing to attract the attention of the forest robbers.
Another bird, called the Indian sparrow, makes her nest of grass, woven like cloth and shaped like a bottle. The neck of the bottle hangs downward, and the bird enters from below. This structure, swinging from a high tree, over a river, is safe from the visits of mischievous animals.
