Yellow canary


The yellow canary is a small passerine bird in the finch family. It is a resident breeder in much of the western and central regions of southern Africa and has been introduced to Ascension and St Helena islands.

Taxonomy

The yellow canary was formerly placed in the genus Serinus but phylogenetic analysis using mitochondrial and nuclear DNA sequences found that the genus was polyphyletic. The genus was therefore split and a number of species including the yellow canary were moved to the resurrected genus Crithagra.
For an overview of finch phylogeny see the entry on finches.

Description

The yellow canary is typically 13 cm in length. The adult male colour ranges from almost uniform yellow in the northwest of its range to streaked, olive backed birds in the southeast. The underparts, rump and tail sides are yellow. The female has grey-brown upperparts, black wings with yellow flight feathers, and a pale supercilium. The underparts are white with brown streaking. The juvenile resembles the female, but has heavier streaking.
This species is easily distinguished from the yellow-fronted canary by its lack of black facial markings, and its bill is less heavy than that of other similar African Crithagra species.
The brimstone canary, with overlapping range, is a known confusion species.

Distribution and habitat

Its habitat is karoo and coastal or mountain valley scrub. It builds a compact cup nest in a scrub.
The yellow canary is a common and gregarious seedeater. Its call is chissick or cheree, and the song is a warbled zee-zeree-chereeo.
