The Zebra Finch, Taeniopygia guttata is the most common and familiar estrildid finch of Central Australia and ranges over most of the continent, avoiding only the cool moist south and the tropical far north. It also can be found natively in Indonesia and East Timor.
The ground-dwelling Zebra Finch grows to a size of about 10 centimetres (3.9 in) long and usually eats grass seeds and spray millet.
Zebra Finches are loud and boisterous singers. 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.
Zebra Finches, like most estrildid finches, are primarily seed-eating birds, as their beaks are adapted for dehusking small seeds. They prefer millet, but will consume many other kinds of seeds, as well.
The number of eggs ranges from two to seven eggs per clutch, with five being the most common number. The time from laying until a fledgling adventures outside will vary with each clutch, but generally good eggs will hatch within 14 to 16 days of laying and young will begin to venture out within about three or four weeks of hatching, and will look full-grown in about three months.
