Red-headed Quelea distribution, type locality circled
Introduction
The Red-headed Quelea was formally described by Karel Johan Gustav Hartlaub, a German physician and ornithologist.
Carl Weiss, a German collector, was the first person to obtain specimens of the Red-headed Quelea (together with other bird specimens, including the Sao Tome Weaver) for The Hamburg Museum. He travelled from 1847-1850 on the ship Adolphus to Sao Tome then to the coast of Ghana, to Principe and back to Sao Tome again. He probably collected the Red-headed Quelea soon after arriving on the island, and sent back many bird specimens which Hartlaub was able to describe in 1848 and later.
The first illustration of a Red-headed Quelea is a colour painting published by Hartlaub in 1850. The second illustration was published by Reichenbach 1863.
