Genus Ploceus - 3. Baglafecht Weavers

There are 8 subspecies of the Baglafecht Weaver, which differ mainly in the colour of the male head and upperparts, and also in the existence or absence of seasonal plumage changes. Females and juveniles differ from the males.

Weaver Wednesday 4 [282] - Weaver themes [19]: Genus Ploceus - 2. Golden weavers

Genus Ploceus - 2. 'Golden' weavers

6 weavers are in the tropical 'golden' weaver group, ie they are yellow or golden with varying amounts of orange, and no black or brown masks. The Cape and Bocage's Weavers are similar, and are thus added in the list below.

Links to species texts for the 'golden' weavers:
Golden Palm Weaver Ploceus bojeri
Taveta Golden Weaver Ploceus castaneiceps
Eastern Golden Weaver Ploceus subaureus
Holub's Golden Weaver Ploceus xanthops
Orange Weaver Ploceus aurantius
Principe Golden Weaver Ploceus princeps
Cape Weaver Ploceus capensis
Bocage's Weaver Ploceus temporalis

The greatest overlap of these weaver species is in East Africa, with 3 species showing much overlap: Golden Palm Weaver, Taveta Golden Weaver, and Eastern Golden Weaver. These 3 species usually have small colonies. Golden Palm Weavers nest mostly in trees (especially palms), and Taveta Golden Weavers nest mostly in reeds (sometimes in trees low over water); Eastern Golden Weavers nest in a wide variety of sites, including trees and reeds, and sometimes have large colonies.
Adult male 'golden' weavers:

Golden Palm Weaver

Eye dark, extensive orange on head
Taveta Golden Weaver

Eye brown, orange crescent on head
Eastern Golden Weaver

Eye red, face orange

Adult female 'golden' weavers:

Golden Palm Weaver

Yellow below, back lightly streaked
Taveta Golden Weaver
from phown 3483
Yellow below, back heavily streaked
Eastern Golden Weaver

Eye reddish, belly white

Holub's Golden Weaver is easy to distinguish from these weavers by its heavy bill and pale eye, and has minimal overlap in range with the above 3 species.

The Orange Weaver occurs from West Africa to Lake Victoria, and overlaps with Holub's Golden Weaver, but not with the other weavers shown above.

The Principe Golden Weaver, Cape Weaver and Bocage's Weaver do not overlap with any other golden weaver.

There may be an unrecognised species in Tanzania, known locally as the Ruvu Weaver, to add to the difficulty of identification of the golden weavers in East Africa.

Weaver Wednesday 4: Weaver themes (Series)

Genus Ploceus - 1. Asian weavers

There are 5 Asian weaver species and they are all in the genus Ploceus. The Baya Weaver is the most widespread and common species. Two Asian weaver species have IUCN threat status as shown below. The Asian weavers are found in savanna, grassland and swampy areas - there are no Asian forest weaver species. The Asian weavers feed on seeds, insects and sometimes nectar. All five species lay plain white eggs.

Finn's Weaver (or Yellow Weaver) Ploceus megarhynchus - Vulnerable
Asian Golden Weaver Ploceus hypoxanthus - Near Threatened
Baya Weaver Ploceus philippinus - Least Concern
Black-throated Weaver (or Bengal Weaver) Ploceus benghalensis - Least Concern
Streaked Weaver Ploceus manyar - Least Concern

Discovery of the Asian weavers

The 5 Asian weavers were described over 111 years, by 4 different authors, from 2 countries. To read more about the discovery of each of these species, click on the name.
Original name Author and year Type locality
Loxia benghalensis Linnaeus 1758 Bay of Bengal, India
Loxia philippina Linnaeus 1766 Pondicherry, India

PHOtos of Weaver Nests in Asia

map
Mosaic of PHOWN records in southern Asia

PHOWN (PHOtos of Weaver Nests) is a Virtual Museum, citizen science project of the Animal Demography Unit, to collect and monitor breeding distributions and colony sizes of weaver birds globally. As of 9 June 2016, there are 26 PHOWN records of Asian weavers, and 18 with colony size information. The statistics of colony sizes from PHOWN are as follows:

Species Min Mean Max n
Asian Golden Weaver 14 17.7 23 3
Baya Weaver 3 14.4 70 15

Many more records are needed to obtain better data on current breeding ranges, nest sites, and colony sizes of the Asian weavers. Please consider taking part in PHOWN - To take part, register and upload records at Virtual Museum (read the "How to" pdf for help).

Weaver Wednesday 4 [280] - Weaver themes [17]: Genus Amblyospiza

Weaver Wednesday 4: Weaver themes (Series)

Genus Amblyospiza

The Thick-billed Weaver is a unique weaver, placed in its own genus. Although a few early authors placed it in a variety of genera (eg. Pyrenestes or Coryphegnathus), for the last century it has consistently remained in Amblyospiza. The sexes are dissimilar. It is polygynous. The nest is woven with thin reed strips and plced between upright reeds. The nest is globe shaped with a side entrance near the top. The entrance is narrowed down in breeding nests. Thick-billed Weavers feed on insects, fruit and hard-shelled seeds. They breed in wetlands but forage in forest edges and gardens when not breeding.

Figures from: capitalba - Shelley 1905b; melanota - PHOWN 8334; montana - PHOWN 8334; unicolor - specimen ZMB_25661; albifrons - Smith 1840a.

Some subspecies differences in male plumages:

subspecies head upper under other
capitalba rufous-brown dark chocolate-brown grey-brown white forehead patch to crown; large contrasts
melanota dark brown black dark brown to grey dark head contrasts with black upperparts,
link between montana & unicolor
montana black black blackish very dark, nearly black
unicolor black but brown wash black-brown black-brown smaller, no obvious colour contrast
albifrons brown dark brown grey-brown  

There is less variation in female plumage, but generally they are paler in populations with rufous-headed males.

Weaver Wednesday 4 [279] - Weaver themes [16]: New weaver longevities

2017-10-18 (804)

Weaver Wednesday 4: Weaver themes (Series)

New weaver longevities

To see the greatest elasped times for southern African weavers, see here.

Red-billed Buffalo-weaver

This species is harder to catch than most weavers, and thus the longevity record was a mere 4 years (ring 5H17931). On 21 Oct 2006 Frik du Plooy ringed a Red-billed Buffalo-weaver at Wolfhuiskraal Farm, north of Pretoria, South Africa, as an adult female. Nine years later Frik was near the farm when he observed a Pearl-spotted owlet that caught this weaver. The new longevity record for this weaver is 9y 9m 25d (ring D55851).

Thick-billed Weaver

The longevity record was 10 years (ring 4H16349), for an adult female. On 18 Sept 1995 Susan Schoeman ringed a Thick-billed Weaver in Lydenburg, South Africa. The bird was sexed as an adult female but with mass 49g, indicating that it should have been listed as a male (and presumably an immature male, else it would have been listed as an adult male). Brian Jones found this bird dead 21 years later, near the aviary at the Moholoholo rehab centre, 76kms from the ringing site. A photo of the bird and ring were sent to SAFRING, confirming that the ring number was not misread. The photo also shows that the bird was an adult male.

The new longevity record for this weaver is 21y 6m 2d (ring 493950).

This is a new world record for any weaver in the wild, increasing the previous record by several years (16.5 years for a Seychelles Fody). There are several records of weavers exceeding 20 years in captivity.
