A large canary with different-looking males and females. The male has bright yellow underparts, yellow-green upperparts, and a well-marked face pattern. The female is drab gray-brown with streaky underparts, yellowish edges of the wing feathers, and a yellow rump. Pairs and small groups occupy dry rangelands including coastal scrub, Karoo, and arid thornveld, where they are resident and nomadic, moving when food becomes scarce. The larger Brimstone Canary has a chunkier bill than Yellow Canary and prefers moist coastal thickets and woodland.
