Description
The Drakensberg Siskin averages 13–14 cm in length. The tail has white sides, a feature which is diagnostic for both sexes, and especially visible in flight. The adult male has a faintly streaked light brown back, light brown wing coverts, rump and upper tail, and yellow underparts. The head and nape sides are yellowish grey and olive. The throat is bright yellow, but the rest of the underparts are a somewhat duller shade.
The female has similar but duller upperparts and has no yellow in the plumage. The head and underparts are buff with much fine dark brown streaks on the head and breast. The juvenile plumage is much like the female’s but with heavier streaking.
There is no range overlap with the slightly smaller Cape Siskin, which has white spots on the flight feathers and tail and more uniform upperparts.
The Drakensberg Siskin’s call is a schwee, often given in flight. and the song, like that of Cape Siskin, is a weak, pleasant warble similar to the Yellow-fronted Canary.

Famous quotes containing the word description:
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
