Introduction

The Long-tailed Widowbird was formally named by Pieter Boddaert, a Dutch naturalist, in 1783. Boddaert published fifty copies of an identification table of Edmé-Louis Daubenton's Planches enluminees, assigning Linnean binomial names (scientific names) to the coloured plates. Many of these names were the first scientific names to be proposed, and so they remain in use today.

Georges-Louis Leclerc, Coount of Buffon was the first to describe the Long-tailed Widowbird, but he did not accept the binomial system of Linnaeus and so he is not credited as the formal author of this species. Buffon described many birds and other animals in a series of volumes (see here). The 9 bird volumes were published between 1770-1783 and Buffon commissoned Edme-Louis Daubenton, to supervise a book of illustrations - the coloured engravings by Francois-Nicolas Martinet were published in 1783 as Planches enluminees.

In Buffon's description of the Long-tailed Widowbird in 1778, he provided the French name La Veuve a epaulettes (The Widow with shoulder patches). Buffon noted that the bird originated from Cap de Bonne Esperance, the Cape of Good Hope. Buffon also gave the plate number of Martinet's colour engraving, although this was only published 5 years later.

Buffon listed the Long-tailed Widowbird as coming from the Cape of Good Hope, which could mean the Cape in its broadest sense, ie either the Western or Eastern Cape. Clancey eventually restricted the locality to the Eastern Cape, as the Long-tailed Widowbird does not occur in the Western Cape. Buffon had many correspondents who sent him specimens from different places in the world, but no details are published for the Long-tailed Widowbird as to who collected this species.

Meaning of names

progne (Latin) = a swallow, from Greek mythology = 'Prokne', a daughter of Pandion, who was transformed into a swallow. Read the myth in wikipedia. Presumably Boddaert heard about the display of the Long-tailed Widowbird and likened it to the fluttering flight of a swallow.

Alternate names

Giant Whydah, Great-tailed Widow Bird, Long-tailed finch, Progne Widow-bird, Sakabula (latter is a Zulu name

Collector

Unknown.

Date collected

Before 1778, when Buffon wrote about this species.

Locality collected

Eastern Cape, South Africa.

Type specimens

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

Introduction

The Village Weaver was described by Philipp Ludwig Statius Muller in 1776. Muller was a German zoologist who published a German translation of Linnaeus's Natursystem. The supplement in 1776 contained the first scientific classification for a number of species, including that of the Village Weaver. Muller gives his source as Buffon, a French naturalist who was the director at the Jardin du Roi, now called the Jardin des Plantes.

Although Linnaeus had access to the bird descriptions in Brisson 1760, strangely he did not describe the Village Weaver in his 12th edition.

Buffon based his work largely on that of Mathurin Jacques Brisson. Brisson gave the first names ever to the Village Weaver, as "Le Pincon du Senegal" (French) and Fringilla senegalensis (Latin). Brisson noted that the Village Weaver originated from Senegal, from where it had been sent to RAF de Reaumur in France by Michel Adanson, who also collected the Red-billed Quelea.

The first colour illustration of the Village Weaver is in the book by Edme-Louis Daubenton, containing coloured engravings by Francois-Nicolas Martinet.

Scientific citation

Oriolus cucullatus Statius Muller 1776 Natursyst., Suppl., p.87 Senegal.

Meaning of names

cucullatus (Late Latin) hooded (L. cucullus, a hood or cowl).

Alternate names

Black-headed Weaver, Black-hooded Weaver, Layard's Black-headed Weaver, Mottled Weaver, Mottled-backed Weaver, Spot-backed Weaver, Spotted-backed Weaver, V-marked Weaver.

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

Linnaeus' type description of the Red-billed Quelea (1758)
Linnaeus C. 1758. Systema naturae per regna tria naturae, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis. Tomus I. Editio decima, reformata. pp. [1-4], 1-824. Holmiae. (Salvius).

Linnaeus provided the formal descriptions for 9 weavers. The tenth edition (1748) of Systema Naturae is considered the starting point of zoological nomenclature, making it an important taxonomic work. The translation of the Latin title is "System of nature through the three kingdoms of nature, according to classes, orders, genera and species, with characters, differences, synonyms, places". There are several online copies, e.g. here (55 MB).

Five weavers were formally described by Linnaeus in this edition (and 4 more in his 12th edition in 1766). His descriptions were brief and without illustrations - see text for the Red-billed Quelea (figure right). The table below shows the names, and type localities of the weavers he described. These columns are follwed by type locality corrections published later by other authors, and the current names of the species. Linnaeus did not see all the specimens himself - he compiled descriptions based on earlier works. The links below go to weaver species accounts where you can read the details of how these species were discovered by Europeans.

Linnaeus listed a species, Loxia sanguinirostris (p173) which was also considered to be the Red-billed Quelea by early workers but is now considered indeterminate. A full list of all bird species in his 10th ed is here.

The nine earliest weavers to be described are relatively common, widespread species, but a key characteristic is that they occur near the coast and on the trading route of the early ships from the far east to Europe. Thus 2 weavers are from the Indian coast, 1 from Madagascar, 2 from the Cape Peninsula, 1 from Angola, 1 from Gambia and 2 from Senegal.

PAPER: Weaver movements in Cape Town

Abstract. Urbanization, a fast growing and destructive human land use, causes local extinctions, biotic homogenization and fragmentation of natural habitats. Understanding how the nature of the urban matrix affects the species residing within a city’s fragmented habitats is an important founding component of urban conservation. This study investigated the influence that the urban matrix, as well as patch isolation, size and quality, had on weaver bird movement into and out of wetland sites in Cape Town, a growing city within a global biodiversity hotspot. Weaver bird movement data from 42 wetland sites were obtained through a long term mark-release-recapture project. Distance-based linear models revealed that site proximity was important as a predictor of weaver movement into and out of sites, while the site variables (wetland size, bird abundance and weaver colony size) had limited and inconclusive influence. Once the variation explained by the proximity and site variables had been accounted for, the composition of the urban matrix and the presence of rivers as potential movement corridors (measured at three spatial scales) had little influence on weaver movement. The finding that proximity (or site isolation) influences weaver movement has important implications for maintaining current landscape connectivity. Habitat isolation, resulting from further habitat removal or destruction, could be expected to reduce movements of weavers, and potentially other species, among patches of favourable habitat. Weavers are robust, vagile birds that do well in the presence of humans and may not be highly sensitive to the nature of the urban matrix. Research into how other, less resilient and vagile species respond to the degree of urbanization in the matrix between wetlands would contribute further to our knowledge of urban biodiversity in this global biodiversity hotspot.

Bird ringing data was collected between January 2007 and September 2013 for this study. Weaver birds were ringed at 101 locations, associated with 31 wetlands in the Cape Town region. Four weavers were studied:
Cape Weaver Ploceus capensis
Southern Masked Weaver Ploceus velatus
Southern Red Bishop Euplectes orix
Yellow Bishop Euplectes capensis
