Yellow canary

Yellow canary
The yellow canary (Crithagra flaviventris) 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 (including canaries) 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.

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.
The Canary bird is set aside from other pet birds because of their beautiful singing ability.
Canaries are known for their beauty and their song and have been kept as pets since the 1400s. They are not companion birds and are better admired from afar, but this doesn't make them any less of a great pet. They do spend a lot of time in their cages, so you need an adaquately sized cage with perches on either end to provide them with maximum flying space.

If you want a Canary that sings, you will need to find a male. If this is very important to you, you should arrange ahead of time with the breeder to be able to return the bird if it proves to not be a singer. Keep in mind that males sing to attract females, so they should not be kept in pairs. They also don't sing in the summer because it is molting season. We have also heard to not put mirrors in their cages because Canaries are very territorial and they may see this "second bird" as a threat.

The most commonly kept Canary birds are the American Singer, the Border Fancy, and the Red Factor. The American Singer is a song Canary (well known for singing), the Border Fancy is a type Canary (a popular type), and the Red Factor is a color Canary (well known for color--the more red, the more valuable).
