Introduction

The Taveta Golden Weaver was formally described by Richard Bowdler Sharpe, an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history.

The Taveta Golden Weaver was collected by HCV Hunter, an English zoologist and hunter who is better known for discovering and collecting the Critically Endangered antelope, the Hirola or "Hunter's antelope", in 1888 along the Tana River in Kenya.

Hunter collected the Taveta Golden Weaver along the Useri River (Shelley 1905b) near Taveta. Hunter collected a large number of birds in the Mt Kilimanjaro area in June to August 1888. The collection was written up in 1889 by Shelley, who described several new species. However, he listed the weaver as an Eastern Golden Weaver and it was only in 1890 that Sharpe realised that Hunter's weaver was a new species.

The first illustration of the Taveta Golden Weaver was of the head of the type specimen, published by Sharpe (1890) with the heads of similar species. The next illustration was of an adult male in Reichenow (1902), considered to be a new subspecies at the time.

Identification. The Taveta Golden Weaver is a bright yellow weaver with a very restricted range in southern Kenya and northern Tanzania. The male is golden yellow, with chestnut crown ending in sharply defined crescent on nape, and chestnut band on breast. The female is yellow without orange and has a heavily streaked back and 2-tone bill (dark above, yellowish below). The juvenile is browner above and buffy below. In captive birds, male nestlings on day 14 were heavier than female nestlings, with little overlap, but sample sizes were small (7 males, 13 females - see Sex of Taveta Golden Weaver chicks).

More measurements are needed for this species - a sample of 7 males ringed near Arusha had larger wing and tail and shorter bills than the measurements provided for 8 males (possibly museum specimans) in Birds of Africa). It was first collected near the town Taveta, giving rise to its English name.

Distribution. In Kenya, the The Taveta Golden Weaver is found in the Amboseli and Taveta areas, and Lake Jipe. In Tanzania, it occurs along the Pangani River, around Mt Meru and Kilimanjaro (see map right, based on Birds of Africa). No subspecies of the Taveta Golden Weaver are recognised, although one other has been proposed. It is common but very local.

Habitat. The Taveta Golden Weaver inhabits woodland and dry bush country, and moves into swampy lowlands to breed.

Food. The diet of the The Taveta Golden Weaver is seeds, including grass seeds, and maize, and ants have been recorded.

Breeding. The Taveta Golden Weaver is probably polygynous. It breeds in colonies in swampy or flooded areas. Breeding areas may be deserted suddenly and completely, for weeks or months at a time. It is not clear if this follows a regular pattern in Tanzania.

The nest is spherical or ovoid with no entrance tube but a slight porch. The nest is woven of strips of reed leaf-blades. Nests are usually suspended over water in reedbeds or bulrushes, and sometimes in low trees overhanging water. It sometimes nests is association with other weavers.

The eggs are olive green with fine darker flecks. Not much more is known about breeding.
