Weaver Species Photo Gallery ... Species Index of Weavers


The Weaver Birds or Weaver Finches (Ploceidae) are small birds that are related to the finches.

They are named for their elaborately woven nests (the most elaborate of any birds).

The weaver group is divided into the buffalo, sparrow, typical, and widow weavers.


Distribution / Range

Most occur naturally in, sub-Saharan Africa. A few species exist in tropical Asia and in Australia.

Within their range, they sometimes cause crop damage and are, therefore, considered agricultural pests.


Description

The Weavers have strong, rounded, conical bills.

The plumage of the males is brightly colored, usually in red or yellow and black.

Some species show variation in color only in the breeding season.

Weaver birds typically breed in bird colonies that are typically found close to water bodies. The malesbuild their nests together, often several to a branch.

Usually the male birds weave the nests and use them as a form of display to lure prospective females.

The sparrow weavers, for example, build apartment-house nests, in which 100 to 300 pairs have separate flask-shaped chambers entered by tubes at the bottom.

Most species weave nests that have narrow entrances, facing upside down.

Male weavers buildelaborately woven nests that vary in size, shape, material used and construction techniques from species to species. Materials used for building nests include fine leaf-fibers, grass and twigs.

Many species weave very fine nests using thin strands of leaf fiber, and some like the buffalo-weavers, however, form massive untidy stick nests in their colonies, which may have several spherical woven nests within.
