Introduction

The Lesser Masked Weaver was formally named by Wilhelm Peter Eduard Simon Rüppell, a German naturalist and explorer, especially in north-east Africa. Rüppell was the first naturalist to travel through Ethiopia and many birds are named after him.

The Lesser Masked Weaver was collected by Major Sir William Cornwallis Harris, an English military engineer, artist and hunter.

Harris led a British diplomatic mission (1841 to 1843) from Bombay to Sahle Selassie, Negus of Shewa, at the time an autonomous district of Ethiopia, with whom they negotiated a commercial treaty. Harris collected birds and other scientific data during the trip. Harris wrote about these travels in 3 volumes (The highlands of Aethiopia) in which he makes occasional reference to birds, but does not appear to have written about the Lesser Masked Weaver which he collected. The type specimen was taken to the East India Company Museum and later [between 1858 and 1971] transferred to the British Museum.

Rüppell illustrated many of the birds he described, but did not illustrate the Lesser Masked Weaver. The first illustration of a Lesser Masked Weaver is a colour painting of its head in Heuglin 1871. Interestingly, the species was not illustrated again for many decades and the second illustration pertaining to this species is a photo of a nest in Hoesch 1936.
