The foreign finches family can be divided in two groups, Australian Estrildid and African Estrildid
The Australian Estrildid with the zebra finch and gouldian finch as the most important examples. In aviculture these birds have an established value.
The African Estrildid declined significantly with the import ban several years ago. Breeding in aviculture has become very important.
All mixture for tropical finches contain a high amount of round seeds, like millet and panicum.
