Zebra Finch

The Australian zebra finch has the most extensive mainland distribution of the Australian estrilids, being found in about 75% of mainland Australia. This species is generally not found on the coasts, except for the arid western edge.
The zebra finch primarily eats grass seeds, feeding mostly on semi-ripe and ripe seeds (although it also takes dry seeds).

Australian zebra finches are loud and boisterous singers. Their calls can be a loud beep, meep, oi! or a-ha!. Their song is a few small beeps, leading up to a rhythmic song of varying complexity in males. Each male's song is different, although birds of the same bloodline will exhibit similarities, and all finches will overlay their own uniqueness onto a common rhythmic framework. Sons generally learn the song of their fathers with little variation. There is a critical sensitive period during which juvenile males learn their songs by imitating a mature, male tutor. Subsong (early, poorly structured vocalisations) evolve into 'plastic song'. This plastic song is variable between renditions but begins to incorporate some recognisable elements of tutor songs.
