- Species: Guttata
- Subspecies: Taeniopygia guttata
The zebrafincf (Taeniopygia guttata) is the most common and the most familiar of all the plants in central Australia.
2. Subspecies and distribution
There are two distinct subspecies.
Taeniopygia guttata guttata, the zebrafinch of Timor, extends from Lombok in the Sunda Islands or Nusa Tanggara in Indonesia to Sermata, in addition to the coastal areas around the Australian mainland. The other subspecies is Taeniopygia gutatta castonatis. The latter is found over most of mainland Australia and some of these varieties are considered domestic.
Morphological differences between the two subspecies include differences in size. Taeniopygia guttata guttata is smaller (8 cm) than Taeniopygia guttata castanotis and does not have the same distinctive mark on the throat and upper chest.
This bird measures 8 to 10 cm (wild form) or 12 to 14 cm (domestic form) for a mass of about 15g. The male utters a rather nascent song and call cry.
This bird can live from 7 to 10 years. It is a robust bird that can withstand temperatures of -15 ° C, knowing that it can survive at least + 40 ° C. 5. Habitat zebrafinch inhabit the open steppes of Australia with scattered bushes and trees, but have adapted to human disturbances, taking advantage of human-made waterholes, and open spaces through deforestation. They go to cities and come to Australia everywhere.

6. Reproduction in the wild
The zebrafinch breeds after heavy rains have occurred in its natural habitat at any time of the year. Adaptable and versatile in the construction of their nests, wild zebrafinch can settle in niches, caves, bushes, maquis, rabbit terriers, on termite nests, see in the holes present in human manufacturing structures. Outside breeding periods, nests are also used for nocturnal bird rest. The laying can range from 4 to 6 eggs with a frequency of one per day, the incubation is provided by both the female and the male and lasts about 13 days. 3 weeks later, the cubs leave the nest. At the juvenile stage the beak is black. In captivity, zebrafinch nest in all kinds of nests, and can breed all year (if the right conditions are reproduced). It's birds are reputed to breed easily.
Zebrafinch have extremely gregarious behavior, and it is extremely rare to see an isolated individual. zebrafinch therefore prefer to evolve in groups.
zebrafinch are sometimes used to model avian populations. They are also a model for studying the brain's ability to interpret sounds, thanks to their ability to recognize and respond to the songs of their peers. Their popularity as a subject of study also comes from the ease of reproduction.
