NEST OF ASTRILDA, FROM SENEGAL.
We are now about to enter upon a description of one of the most remarkable groups of African birds, the strange forms of whose very varied nests are no doubt familiar to many of our readers. It would be difficult to imagine a more beautiful sight than that presented by a settlement of these most artistic WEAVERS, their nests hanging not singly, but by dozens, from the branches of a tree, which is generally selected with a view to being in the immediate vicinity of water. So strong and firm is the work of the little architects that the rain and blasts of years will not shake their abodes from their foundations, and it is by no means uncommon to see a tree thickly covered with the consecutive labours of many generations, and literally bending under the weight of these curious and elegant constructions. The central and western parts of Africa are particularly resorted to by these birds, also long accounts are given us of their abundance in Java and Madagascar.
WEAVER BIRDS.
NEST OF WEAVER BIRD SLIT OPEN.
The Weaver Birds (Plocei) are large Finches, with bodies somewhat elongated, having slender, or in some cases, short broad beaks, long wings, tails of moderate length, and very bright coats, the latter often varied during the breeding season by a peculiar kind of plumage. Yellow and yellowish red are usually the principal tints in the coloration of the feathers; but species are found in which black, red, white, or grey predominate. The head and face are generally dark, the back greenish or yellowish red, the lower part of the body dark yellow, or of a light or dark red. Like other Finches, the Weaver Birds are extremely social, living, as we have said, in large settlements during the period of incubation, and flying over the country in company with thousands of their feathered brethren during the remainder of the year. Immense damage is done by these swarms to the fields over which they pass, and about which they remain until the time comes for returning to their old breeding-places. Shortly after the moulting season the work of building commences, and several months are generally occupied in diligent labour before the newly-constructed homes will suit the requirements of the fastidious owners, who frequently tear a whole nest to pieces, and entirely recommence their labours, rather than rest content with a performance that is not quite satisfactory. The nests of the various species of Weaver Birds differ considerably in their shape and general structure, some building a detached residence (see p. 165), in which the male luxuriates, whilst his spouse is busied with the cares of her family; others, again, are so large as to contain numerous compartments, the whole colony working so close together as to form, not many separate nests, but one large establishment (see p. 168). Fibres, slender twigs, or blades of grass, are the materials usually employed in the construction of these edifices, the whole being woven tightly together, after having been rendered more flexible and adhesive by an application of saliva from the little artist's beak. The greater number of such settlements are formed of nests containing merely the chamber for the young and the apartment arranged by the male for his own occupation. Some males, however, build separate nests for themselves. Both are represented in our engravings.
Many tribes of Africans tell wonderful tales about these creatures and their homes, some of which border upon the marvellous. The Malays have a saying that "He who can remove a Weaver Bird's nest without breaking it, will find a golden ball within;" and there is a popular belief in Africa that the lumps of clay so often found in these little dwellings are employed by the tenant as a kind of candlestick in which it fastens the fire-beetle it is supposed to employ to light its tiny apartment by night. The Weaver Bird lays many times during the year, and feeds its somewhat numerous family upon insects; these latter, combined with various kinds of seeds, also constitute the food of the parents. In spite of the injury done to the fields, but few precautions are taken by the natives to protect themselves against the depredations of these ingenious architects, who might live out the full term of their natural life were it not for the attacks made upon them by their numerous enemies, who are ever on the watch around their habitations. Our engraving (p. 175) represents the manner in which the monkey, one of the most formidable of their foes, obtains its prey. It is in hope of baffling the attempts of such unwelcome visitants that the Mahali Weaver Birds insert thorns with the points outwards into the walls of their nests, thus enabling the occupants to rest quietly, without fear of seeing their young carried off by snakes and other intruders. Large numbers of these curious and interesting birds are annually exported and sold at low prices, so that our readers need have no difficulty in witnessing their constructive powers, which are often displayed to great advantage in a cage. One of the most celebrated of this group is
