themselves to pass through. We learn from travellers in Africa that the nests of this species are occasionally found of a much larger size than those described, some measuring from five to six feet in length, and four to five in breadth and height; these enormous structures, however, are not occupied as a residence by one family, but are joint property, some containing as many as from three to eight distinct nests, in each of which may be seen the three or four white eggs, spotted with brown, that constitute the brood. As may well be imagined, the noise and bustle around one of these compound nests must be heard to be appreciated; indeed, the vicinity of a settlement is unmistakably proclaimed by its busy and loud-voiced proprietors. The Black Buffalo Weaver Bird breeds at very various seasons of the year, the time depending on the part of the continent that it inhabits. Its flight is hovering, very light, and produced by a slow motion of the wings, which at each stroke are raised high towards the back. When upon the ground it runs with ease, and is most adroit in its movements among the branches of the trees to which it resorts. THE WHYDAH OR WIDOW BIRDS. The WHYDAH OR WIDOW BIRDS (_Viduæ_) form the group to which we shall next allude, as being most nearly allied to the family of the Weavers. Whether the members of this family have had the name of _Widow_ bird assigned to them by reason of the blackness of their plumage, is a question we shall not attempt to decide; some naturalists affirm that the word _Widow_ is merely a corruption of _Whydah_, the name of the place from which they were first obtained by the Portuguese. These birds are Finches of moderately large size, remarkable from the fact that the plumage they acquire during the breeding season is distinguished by the peculiar form and great length of a portion of the tail-feathers, this decoration being laid aside as soon as the period of incubation is over, and replaced by another of less striking appearance. The other distinguishing characteristics of this family are the short, conical, and pointed beak, somewhat dilated at its base and compressed at its tip, and the wings of moderate length. The plumage of the male is black above, intermixed here and there with white and red; the lower part of the body is red, gold colour, or white. All the various species of _Viduæ_ are to be met with throughout the entire continent of Africa, though some countries in particular might be mentioned as the actual homes of certain members of the group. In their habits the Widow Birds bear a closer resemblance to the Buntings than is usually observable in the Finch tribe; they live during the breeding season in pairs apart from the rest, or else not unfrequently in a state of polygamy, and only congregate in large flocks and fly about the country after the period of incubation and the moulting season are over. As may be easily imagined, the movements of
