About Crithagra symonsi (Roberts, 1916)
The Drakensberg siskin (Crithagra symonsi) averages 13–14 cm in length. Both sexes have a diagnostic white-sided tail, a feature that is especially visible when the bird is in flight. The adult Drakensberg siskin male has a faintly streaked light brown back, light brown wing coverts, rump, and upper tail, with yellow underparts. The sides of the head and nape are yellowish grey and olive. The throat is bright yellow, while the rest of the underparts are a somewhat duller yellow shade. The female Drakensberg siskin has similar upperparts to the male, but they are duller, and she has no yellow in her plumage at all. Her head and underparts are buff, with many fine dark brown streaks across the head and breast. Juvenile plumage is very similar to the female's, but it has heavier streaking. The Drakensberg siskin does not share a range with the slightly smaller Cape siskin, which has white spots on its flight feathers and tail, plus more uniform upperparts. The Drakensberg siskin's call is a schwee, often made in flight. Its song, like that of the Cape siskin, is a weak, pleasant warble similar to the song of the yellow-fronted canary.
