Zebra Finch

The Zebra Finch is a small, common estrildid finch native to the dry interior of Australia, and one of the most intensively studied songbirds in the world for research on vocal learning and behavior. Wild populations are found across most of the Australian mainland, avoiding only the wettest coastal forests.

Males are strikingly patterned, with fine black-and-white barring on the throat and upper breast, a bright orange cheek patch bordered in black and white, chestnut flanks spotted with white, and a red-orange bill. Females are plainer overall, lacking the chestnut flanks and orange cheek patch, with gray-brown upperparts and an orange bill.

Plumage

• Male: black-and-white barred throat/breast, orange cheek patch, chestnut flanks with white spots
• Female: plain gray-brown, orange bill, no barring or cheek patch
• Both sexes: black tail with white barring, red-orange bill

Key field marks

• Very small finch with a red-orange bill
• Male: fine black-and-white barring on the upper breast, orange cheek patch, chestnut side patches with white spots
• Female: plain gray-brown body without barring or cheek patch, but same red-orange bill shape
• Black tail with fine white bars, visible in flight or when perched

Similar species

No other Australian finch shares the male's combination of barred breast and orange cheek patch, making adult males unmistakable. Females can be confused with other plain brown estrildid finches, but the orange bill and small size are useful clues.

Range

The Zebra Finch is found across most of mainland Australia, particularly the arid and semi-arid interior, and is largely absent from the wet tropical and temperate coastal fringes. A separate subspecies occurs on Lesser Sunda islands in Indonesia.

Habitat

It inhabits open grassland, scrub, spinifex country, and dry woodland, usually near water. It is highly nomadic and opportunistic, moving in response to rainfall and can breed rapidly whenever conditions are favorable.

Behavior

Zebra Finches are highly social, gregarious birds usually seen in flocks that forage together on the ground and gather at waterholes, sometimes in large numbers in arid regions.

Voice

The song is a short, distinctive series of nasal, trumpet-like and buzzing notes; the contact call is a loud, repeated "tya" often heard from flocks in flight.

Feeding

They feed mainly on small grass seeds gathered on the ground, and take insects opportunistically, particularly to feed nestlings.

Nesting

Zebra Finches build bulky, domed grass nests in shrubs, tree hollows, or other cavities, and can breed opportunistically at almost any time of year when conditions allow, laying clutches of around 4-6 eggs.
