The nest of the baya is one of the most wonderful things in nature. Description is unnecessary. Every one who has been in India has seen dozens of the hanging flask-shaped structures, while those who know not the Gorgeous East must be acquainted with the nest from pictures.
On account of its champagne-bottle shaped nest, the weaver is sometimes known as the bottle bird; I have also heard it called the hedge sparrow.
It makes no attempt to conceal its exquisitely woven nest. It relies for protection on inaccessibility, not concealment. Every animal _badmash_ can see the nest, but cannot get at it. It hangs sufficiently high to be out of reach of all four-footed creatures. The ends of the entrance passage are frayed out so as to baffle all attempts on the part of squirrels and lizards to reach the treasures hidden away in it.
Both cock and hen work at the nest, the cock being the more industrious. The fibres of which it is composed are not found ready-made. The birds manufacture them out of the tall elephant grass which is so common in India. The weaver alights on one of the nearly upright blades and seizes with its beak a neighbouring blade near the base and makes a notch in it; it next seizes the edge of the blade above the notch and jerks its head away. By this means it strips off a thin strand of the leaf; it then proceeds to tear off in a similar manner a second strand, retaining the first one in its beak; in precisely the same way a third and perhaps a fourth strand are stripped off. The tearing process is not always continued to the extreme end of the blade; the various strands sometimes remain attached to the tip of the blade. The force with which the bird flies away usually suffices to complete the severance; sometimes, however, it is not effected so easily, and the bird is pulled back and swings in the air suspended by the strands it holds in its bill. Nothing daunted, the weaver makes a second attempt to fly away, and if this is not successful, continues until its efforts are crowned with success.
The grass which is used in nest construction is impregnated with silicon to such an extent that I experienced considerable difficulty in extricating from my pocket some of the fibres which, on one occasion, I took home with me. The material is thus eminently suitable for weaving purposes.
