Gelbscheitelgirlitz Serinus canicollis

Rather plain seedeater with a gray nape, yellow underparts, and olive-green back. Found in fynbos, woodland, grassland, and gardens. Usually in small flocks. Distinctive call is a short, high-pitched trill, often given in flight. Song is a frantic, warbled jumble of notes. Separated from similarly sized seedeaters by gray nape and lack of facial markings.
