Introduction

After Linnaeus published his 10th edition of Systema Naturae, he came across many more species. His 12th edition (Linnaeus 1766) contains several more weavers, the first being the Cape Weaver. Linnaeus gave a very short description, based on the longer description in Brisson 1760.

Mathurin Jacques Brisson, a French zoologist, wrote his book on birds in several volumes, each page having 2 columns (one in French and one in Latin). Brisson gave the names "Le Carouge du Cap de Bonne Esperance" (French, for Oriole of the the Cape of Good Hope) and Xanthornus Capitis Bonae Spei (Latin). Many of Brisson's Latin names for birds were given before Linnaeus, but they were not constructed as binomial names, and thus do not qualify as scientific names.

Brisson noted that the Cape Weaver originated from the Cape of Good Hope. This could be from anywhere in the Cape but most likely the Cape Weaver was taken from the Cape Peninsula. The Cape Weaver specimen was housed in the Aubrey abbey in Paris.

The Cape Weaver was first illustrated by Francois-Nicolas Martinet, under the supervision of Edme-Louis Daubenton, a French naturalist, in 1783. Martinet engraved and painted over 1000 colour plates for the Histoire naturelle (1749-89), providing the largest collection of bird paintings in the world at the time. Troupiale olive de Cayenne

The earliest written record referring to an African weaver that is identifiable, is a record of a Cape Weaver from 1630. Friar Francisco dos Santos was a Portuguese priest on the ship San Gonzales which became stranded in Formosa Bay (=Plettenberg Bay, South Africa) in June 1630. While stranded on land for 9 months, Santos wrote about the fauna and flora, the earliest record for the region. He described hanging weaver nests and the only known Ploceus weaver in Plet at that time was the Cape Weaver. Read the fascinating story here.

Two other interesting early records are paintings of weaver nests by Lady Anne Barnard from 1797 in Stellenbosch (PHOWN 4953) and 1798 a farm dam near Porterville (PHOWN 4954). Again, these can only belong to the Cape Weaver, since the Southern Masked Weaver did not occur in the Western Cape before 1900.

PAPER: Frog nest in weaver nest

African foam-nest tree frog

Abstract. We report that the Afrotropical anuran Chiromantis rufescens may use empty forest weaver bird nests above water for deposition of foam-nests with eggs. Our observation was made in January 2008 at a temporary pond in primary rainforest of Salonga National Park, Democratic Republic of Congo. To the best of our knowledge this is the first ever report of utilization of bird nests by amphibians. We expect that bird nests with their tube-like entrance were difficult to access for frogs and that the choice of this oviposition site was non-random. If so, it may be a response to strong egg predation, e.g. through primates, as known in C. rufescens.

The authors found two cases where African foam-nest tree frogs used the deserted nests of the Blue-billed Malimbe to build their foam-nest. This frog usually builds its nest on branches overhanging water. Read more about the Blue-billed Malimbe.

Weavers eating frogs

Spectacled Weaver eating frog

Weavers generally feed on seeds and insects, although some unusual diet items have been recorded, including small frogs. Four weaver species have been recorded as eating small frogs (from Handbook of the Birds of the World, Vol. 15).

Recently Spectacled Weaver was added to the list as Birdpix record 11090. An adult male Spectacled Weaver snatched a Painted Reed Frog from a bench, and flew up into a tree where it shared the frog with a juvenile (click on the record to see more photos).

Weavers that have been recorded as feeding on small frogs:
Baya Weaver Ploceus philippinus
Black-billed Weaver Ploceus melanogaster
Thick-billed Weaver Amblyospiza albifrons
White-billed Buffalo-Weaver Bubalornis albirostris
Spectacled Weaver Ploceus ocularis

Introduction

Linnaeus 1758 described the quelea with a Latin text, but did not provide a reference. He noted that the species came from India, again an error based on ships from the East Indies picking up bird specimens along the African coast on their return to Europe. In his updated 12th edition of Systema Naturae (Linnaeus 1766), he presented the same plumage description in Latin but corrected the type locality to Africa, and listed Brisson as a reference.

Presumably Linnaeus had access to Brisson's 1760 draft in 1758. Mathurin Jacques Brisson, a French zoologist, wrote his book on birds in several volumes, each page having 2 columns (one in French and one in Latin). For the quelea, Brisson gave the names "Le Moineau à bec rouge du Sénégal" (French) and Passer senegalensis erythrorynchos (Latin). Brisson noted that the quelea originated from Senegal, from where it had been sent to RAF de Reaumur in France by Michel Adanson (the generic name of the Baobab, ie Adansonia, was named after Adanson). Brisson's book has a few engraved illustrations by François-Nicolas Martinet, including one of the quelea.

Edwards 1760 also illustrated the Red-billed Quelea (in colour) in the same year as Brisson. George Edwards called it the Brazilian Sparrow, not being sure if it came from Brazil or Angola. The painting by Edwards was based on a living male in the collection of Mrs Clayton in England, being a different individual to the type specimen.

Linnaeus described many or most of the birds in Edwards, but does not seem to have used the quelea in Edwards (at least not under Linnaeus' genera Loxia or Emberiza).

Scientific citation

Emberiza quelea Linnaeus 1758 Syst. Nat., ed. 10, p.177 "India". Senegal, ex Brisson (see Linnaeus, 1776, Syst. Nat., ed. 12, 1, p.310)

Meaning of names

The origin of the name 'quelea' is unclear and several authors have debated this without there being enough information to come to a definitive conclusion. No African origin of the name has been found despite extensive searches. Linnaeus probably derived quelea from the Medieval name for quail, ie 'qualia' and 'qualea'. The reason for this is also not clear, and the following possibilities have been suggested by different modern authors:
  • quelea and the quails of the Old Testament were both found in enormous flocks.
  • both quail and quelea have similar streaked upperparts and buzzing flight.
  • from quell or to quail meaning "to torment", referring to the destruction of crops by quelea.

Alternate names

Blackfaced Dioch, Cardinal, Common Dioch, Latham's Weaver-bird, Pink-billed Weaver, Quelea Finch, Quelea Weaver, Red-billed Dioch, Red-billed Weaver, Russ' Weaver, South African Dioch, Sudan Dioch, Uganda Dioch

Collector

Michel Adanson, a French naturalist who undertook a collecting expedition to Senegal.

Date collected

Between 1748-1754, the time that Adanson spent in Senegal.

Locality collected

Senegal.

Type specimens

No type specimens known to survive, but the painting of Brisson serves as a type.

Weavers and waterbirds

2014-10-14 (581)
Weavers sometimes breed in association with waterbirds, especially colonial waterbirds. Weavers have nested in heronries including various combinations of the following waterbirds: Reed Cormorants, Darters, Black-headed Herons, Grey Herons, Cattle Egrets, Marabou Storks, Pink-backed Pelicans, and other species. There are also many records of weavers nesting with solitary waterbirds, especially Hadeda Ibis, and also Hamerkop.

Village Weaver colony with heron nest

Seven weaver species have been recorded nesting with waterbirds, based on records scattered through the scientific literature. The PHOWN database has many records for the Cape Weaver and some for the Village and Southern Masked Weavers (see PHOWN records). However, there are likely to be more weaver species that nest with waterbirds.

Weavers that have been recorded as nesting in association with waterbirds:
Southern Masked Weaver Ploceus velatus
Baya Weaver Ploceus philippinus
Cape Weaver Ploceus capensis
Lesser Masked Weaver Ploceus intermedius
Orange Weaver Ploceus aurantius
Village Weaver Ploceus cucullatus
Vieillot's Black Weaver Ploceus nigerrimus
