2 of the 65 weavers can be found in Western Cape.
9 of the 65 weavers can be found in South Africa.
60 of the 65 weavers can be found in Africa.
5 of the 65 weavers can be found in Asia.
You are most likely to spot these weaver birds in sub Saharan Africa, and specifically in DRC, Tanzania and Angola.

Ploceus is a genus of birds in the weaver family Ploceidae.

I have only photographed two of the numerous 65 of weaver birds in this genus; The Southern Masked Weaver and the Cape Weaver. These are the only two species of weaver birds that can be found in my home province of Western Cape. The next weaver bird I will target is the Village Weaver, which can be found in our neighboring province of Eastern Cape. The biggest city there is Port Elizabeth, and will be probably the most accessible for most people. The Cape Recife in Port Elizabeth looks like a good bet to go and look for Village Weaver. I will update this blog post as soon as I get to photograph this bird.  

The Southern Masked Weaver is probably the most common weaver in South Africa. Some of the places where I have photographed the Southern Masked Weaver are;
Paarl Bird Sanctuary, Paarl, Western Cape,
Strandfontein Bird Sanctuary, False Bay, Western Cape,
Val de Vie, Paarl, Western Cape,
Rondevlei Nature Reserve, False Bay, Western Cape

A non-breeding male Southern Masked Weaver photographed at Inthaka Island, in the Western Coast area of Cape Town, in the Western Cape.
The southern masked weaver is 11-14.5 cm long with a short, strong, conical bill and pinkish brown legs. The adult male in breeding plumage has a black face, throat and beak, red eye, bright yellow head and underparts, and a plain yellowish-green back,
The female has a pinkish-brown bill, brown or red-brown eye and is dull greenish-yellow, streaked darker on the upper back. The throat is yellowish, fading to off-white on the belly. The non-breeding male resembles the female but retains the red eye. The juvenile of this species is like the female.
The call is a harsh swizzling, similar to other weavers. It also utters a sharp chuk alarm note.
The southern masked weaver nests in colonies, mainly from September to January. Males have several female partners, and build a succession of nests, typically 25 each season. The nests, like those of other weavers, are woven from reed, palm or grass. A female will line a selected nest with soft grass and feathers. The nest is built in a tree, often over water, but sometimes in suburbia. This weaver also nests in reeds.
The southern masked weaver lays eggs of a various colour and this helps it to evade parasitisation by cuckoos because the cuckoo has no way of knowing what kind of eggs are inside the weaver's nest until it has entered the nest to attempt to lay one itself. Eggs of the wrong colouration are ejected by the nest owners.
The southern masked weaver is usually seen singly or in small groups. It may also form larger flocks, alone or with other seed eating species. It eats insects, seeds and nectar, and will come to feeding tables.
The Southern Masked Weaver is almost present everywhere in the southern African coubtries as seen in the map below.



The Cape weaver is the second weaver species that can be found in Western Cape. Some of the places I have photographed the Cape Weaver are;
Val de Vie, Paarl, Western Cape,
Helderberg Nature Reserve, Helderberg, Western Cape,
Rondevlei Nature Reserve, False Bay, Western Cape

A Cape Weaver photographed at Helderberg Nature Reserve, situated in Somerset West, on the eastern side of Cape Town.
The Cape weaver (Ploceus capensis) is a resident breeding bird species endemic to South Africa.
This common species occurs in grassland, agricultural and fynbos habitats, often near rivers. It breeds in noisy colonies in trees (often willows oreucalyptus, rarely palms) and reedbeds.
This weaver builds a large coarsely woven nest made of grass and leaf strips with a downward facing entrance which is suspended from a branch or reed. The hadada ibis will sometimes nest in the weaver colonies. The Cape weaver feeds on a wide variety of seeds, grain and insects. The calls of this bird include a harsh azwit, azwit.
The Cape weaver is a stocky 17 cm long bird with streaked olive-brown upperparts and a long pointed conical bill. The breeding male has a yellow head and underparts, an orange face, and a white iris.
The adult female has an olive-yellow head and breast, shading to pale yellow on the lower belly. Her eyes are brown. Young birds are similar to the female.
The Cape Weaver is endemic to South Africa, as can be seen in the distribution map below.
The next weaver on my list will be the village weaver. The village weaver (Ploceus cucullatus), also known as the spotted-backed weaver or black-headed weaver (the latter leading to easy confusion with P. melanocephalus), is a species of bird found in much of sub-Saharan Africa. It has also been introduced to Hispaniola, Mauritius and RĂ©union.
This often abundant species occurs in a wide range of open or semi-open habitats, including woodlands and human habitation, and frequently forms large noisy colonies in towns, villages and hotel grounds.
This weaver builds a large coarsely woven nest made of grass and leaf strips with a downward facing entrance which is suspended from a branch in a tree. 2-3 eggs are laid. This is a colonial breeder, so many nests may hang from one tree.
The village weaver is a stocky 15–17 cm bird with a strong conical bill and dark reddish eyes. In the northern part of its range, the breeding male has a black head edged by chestnut (typically most distinct on the nape and chest). Towards the southern part of its range, the amount of black and chestnut diminish, and the breeding males of the southernmost subspecies only have a black face and throat, while the nape and crown are yellow. In all subspecies the breeding male has a black bill, black and yellow upperparts and wings, and yellow underparts.
The non-breeding male has a yellow head with an olive crown, grey upperparts and whitish underparts. The wings remain yellow and black.
The adult female has streaked olive upperparts, yellow and black wings, and pale yellow underparts. Young birds are like the female but browner on the back.
Village weaver feeds principally on seeds and grain, and can be a crop pest, but it will readily take insects, especially when feeding young, which partially redresses the damage to agriculture.
The calls of this bird include harsh buzzes and chattering.

The distribution of the Village Weaver stretches over most of the sub Saharan Africa, as well as in some of the Caribbean islands in North America. This species of weaver is not found in the area where I stay, with the closest area to me,  being Eastern Cape.
