This is a cute little modestly colored bird. Japanese amadina is bred in Japan at home. Scientists suggest that its ancestor is the bronze amadine, or it is the product of crossing several species of amadine. As a result of domestication, Japanese amadins have lost caution, are indifferent to the control of the nest, get used to caring people. They are absolutely undemanding to the conditions of detention. They can live and reproduce in the smallest cells. They are also unassuming in feeding.
The total length of the body together with the tail of the Japanese amadina is about 15 cm . Breeders have bred several color variations (morphs) of the Japanese amadina. For example, black and white, yellow-white and white. Crested individuals look charming, but in no case can they be mated with each other.
Visually, the female and the male do not differ from each other in the color of the plumage, but the male usually looks more slender. In addition, the males of Japanese amadines sing a simple, quiet song, and during the courtship they talk in front of the female.
To stimulate the nesting behavior of birds, it is necessary to hang a nest house of the blueberry type with a removable roof. Ideally, it is suspended from an additional cage door from the outside.
After mating, the female lays 4 to 8 white testicles. The incubation period is usually 14-17 days. Both parents take care of the chicks. After 21 days, fully fledged chicks leave the nest house. For about 10 more days, the parent couple feeds the grown-up chicks. They become sexually mature at the age of about 9 months.Due to their uncomplicated breeding and their gullibility, Japanese amadines are very often used as foster parents of rare species of amadines and astrilds.
