Taxonomy

This species has two subspecies:1

  • S. a. alario
  • S. a. leucolaemus
  • Range overlaps with S. a. alario, but extends further north in Namibia, and not as far south or west in South Africa.
  • Male has a pied (rather than black) head, with a white eyebrow, cheeks, chin and throat; female has a faint whitish head pattern similar to that of the male.

Some authorities2,3 consider S. a. leucoleamus a separate species, the Damara Canary, Serinus leucolaemus.
This species was formerly placed in genus Alario by Clements.

Habitat

Arid to semi-arid shrublands and grasslands; also weedy road verges, croplands and gardens.

Behaviour

Found in pairs or family groups when breeding; when not breeding, forms flocks of up to several hundered birds.

Diet

Forages on the ground and in shrubs, trees and grasses for seeds; also eats buds, petals, fruit and termites.

Breeding

Probably monogamous and territorial. The nest is a cup built by the female using dry grass, twigs and bark and lined with plant down; placed within a metre of the ground in a shrub or small tree. Two to five eggs are laid; incubated for 13-14 days by the female.
