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.
A clean paper should be placed at the bottom of the cage and changed on a daily basis. Grass and hay form good nest box substrates.
The star finches are sensitive to temperature changes and do not like cold, damp weather. They should be kept at a temperature of about 55 degrees Fahrenheit in winter. During breeding a temperature of 70 to 75 degrees Fahrenheit is best suited. They need proper sunlight, without which their feathers may become dull.
These active birds get along well with their own group as well as birds of other species provided they have a temperament similar to theirs. They are not shy to people and are good to be observed as well as appreciated.
Like most finches, they too thrive well on seeds. The Siberian, proso, Japanese and German millets are well suited for them. Their diet should also comprise of kale, broccoli tops, grated carrot, lettuce, chopped spinach and apples. Boiled egg or egg food, cuttlebone, and grit provides adequate nutrition. Fresh water should be provided at the foot of their cage on a regular basis.
