PHOWN (PHOtos of Weaver Nests)

PHOWN (PHOtos of Weaver Nests) is a citizen science monitoring project aimed at determining the distribution of colonies or nests of all weaver species globally, and studying the variation in their colony sizes. Counting weaver nests and taking photos allows tracking of changes in weaver breeding effort. This project provides an easy way of monitoring common weavers, while helping the conservation of threatened weavers. Download PHOWN flyer here. To take part, read here.

Total stats possible: There are 117 living species of weavers (species list). There are about 60 countries in Africa, Asia and the Indian Ocean where weavers occur naturally. The current world population is about 6.9 billion humans. The number of records that can be submitted is unlimited (not really, but rather many!).

Introduction

Linnaeus thought this species came from India, or the [East] Indies ("in Indiis"), a common mistake in his day, as the ship bringing this specimen probably came from the far East but stopped at African ports along the way, where African specimens could have been added to the cargo. Gyldenstolpe (1924) first noticed the error, and restricted the type locality to Senegal as the type specimen matched other specimens from Senegal.

Linnaeus noted the source of the type specimen as "mus ad fr", ie. the Museum Adolphi Friderici, a collection maintained by the King of Sweden, Adolf Fredrik.

Swainson (1837) obtained described a specimen from Senegal as a new species (Crimson-crowned Weaver Euplectes flammiceps), but this was later discovered to be the same species as the Black-winged Bishop. Nevertheless, his painting is the first published illustration of this species, many decades after Linnaeus first described it.

Scientific citation

Loxia hordeacea Linnaeus 1758a Syst. Nat., ed. 10, p173 'in Indiis', errore = Senegal, vide Gyldenstolpe 1924.

Meaning of names

hordeaceus (Latin) - of barley; referring to its diet.

Alternate names

Fire-crowned Bishop

Collector

Unknown, but kept in the Museum Adolphi Friderici.

Date collected

Before 1754, since Linnaeus studied the collection from 1751-1754.

Locality collected

Unknown, type locality restricted to Senegal.

Type specimens

The type is in the Swedish Museum of Natural History (Naturhistoriska riksmuseet) in Stockholm. Modern photos of the type are at here.
