The star finch (Bathilda ruficauda) is a seed-eating bird species found in northern Australia. It has a distinctive red face and bill, and broad white spots down its flanks. One of its three subspecies may be extinct.
The star finch is an estrildid finch, between 10 and 12 cm in length, with crimson fore-parts of the head and a scarlet bill. The upper and lower plumage is yellow-green, white spotted on the underparts, the belly more yellow. The upper tail coverts are scarlet, tail feathers are brownish scarlet. The female has less crimson on the head, and generally duller than the male, the immature star finch is olive to brownish with a grey face and head. The broad white spots under its chin and down its flanks give rise to its common name.
