 Similar species
The Yellow-fronted Canary has a more brightly contrasting yellow rump, duller yellow underparts, a white-tipped tail, and is smaller.
Brimstone Canary is larger with a heavier bill and green (not yellow) forehead; more green overall (but notice geographic variation in Yellow Canary with birds from the Cape area being greener). Brimstone Canary has a much shorter supercilium that quickly narrows behind the eye.
White-throated Canary is similar to the female Yellow Canary, but larger, has a heavier bill, is less streaked, and the yellow-green rump contrasts more with the greyish-brown back and mantle.
Southern Africa: Lesotho, South Africa, Botswana, Namibia and south-western Angola.
Introduced to the island of St. Helena and Ascension.
There are four subspecies:1,2
- Highveld (high-altitude plateau) of east-central South Africa and lowlands of western Lesotho
- Male has lemon-chrome rump and underparts and greenish-tellow crown.
- North-central South Africa, Botswana, Namibia and south-western Angola
- Yellower upperparts than nominate, face markings less contrasting, and rump lemon-chrome.
- Lesotho highlands
- Larger than nominate; broader dark centres to crown and back feathers. Female: The sides of the face are darker grey than the nominate, and the throat and breast more heavily striped.
Shrublands, semi-arid savanna, fynbos (a distinctive natural shrubland or heathland, occurring in the Western Cape of South Africa). Also thickets of alien Acacia, gardens, dune vegetation, coastal wetlands and beaches with seaweed.
Conspicuous; in flocks when not breeding, sometimes with other granivores.
Forages on the ground and in forbs (an area of broad-leaved herbs, other than grass) and shrubs, eating flowers, seeds, nectar, insects and small crustaceans.
Monogamous and probably territorial. The nest is built by the female in as little as three days using a variety of plant material. Two to five eggs are laid and incubated for 12-16 days by the female.
Sings from the top of a bush or a tree, also does a display-flight. The song is a fairly long and varied series of warbled phrases and rapid muscial twitters, including "chissick" and "cheree" notes in random manner. Calls "peeoo", "peetyo" and "peelee", also an upslurred "peclyip" and a distinctive "chirrup" or "tirriyip"
