Cape Weaver Ploceus capensis
IntroductionAfter 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.
