White-headed Buffalo Weaver (Dinemellia dinemelli)

Of the huge variety of birds that we see in nature, this small, seed eating finch with a rounded conical bill, which we identify with building nests, is truly a gifted craftsman.  Weaver birds build nests of such intricate design, that no amount of human ingenuity can replicate it, in spite of the numerous architectural designs that man is capable of.
