weaver bird name for the Ploceidae, a family of Old World seed-eating birds closely resembling finches (hence the alternate name weaver finch). It includes a number of so-called goldfinches and waxbill finches that are actually weaver birds, rather than true finches of the family Fringillidae. The weavers are named for the highly complex woven nests built by many species, though others build only crude nests, and the parasitic widow weavers build no nests at all. Most weavers are sedentary, noisy, gregarious, and polygynous, with elaborate courtship rituals. The weaver group is divided into the buffalo, sparrow, typical, and widow weavers. The African buffalo weavers are black-and-brown birds 8 to 10 in. (20.3-25.4 cm) long, that travel in small flocks and build bulky compartmented nests with separate chambers for two or more pairs. Of the 35 sparrow weavers the best known, and in fact one of the most widely distributed and familiar small birds in the world, is the English sparrow native to Europe, W Asia, and N Africa. It is the most successful town and city dweller among birds, and has followed European civilization wherever it has gone; it was introduced to North America in 1852. As common in Asia is the Eurasian tree sparrow (also introduced in the United States), a nuisance in rice fields and sold in great quantities for food. These birds build untidy domed nests with side entrances. Most specialized of the sparrow weavers is the social weaver of Africa, famous for...
