These finches are like the societies, in that you can only tell the sexes apart by observation. For the adventurous finch keeper, or simply someone who wants something out of the ordinary, there are other varieties of finches to try. Gouldian Finches sport brilliant colors and come in many color combinations. They are readily available, and are in the mid to high-price range depending on what colors the hobbyist wishes to purchase. Owl finches, also called Bichenos, look like tiny owls with their white faces framed by a black band.
Star finches boast a brilliant red head that stands out against their olive to yellow green plumage.
These are just a few species, chosen to show you the difference in coloration. A quick look through any beginning finch book will show you the wide variety available. For beautiful, low-maintenance birds, finches cannot be beat. These birds offer personality in a pint sized package. After all, they're Mother Nature's perfect little jewels.
