There are also silvers which are pale silvery gray and fawns which are light milk chocolate. Add pied markings to all of these mutations and a rainbow of colors emerge. The females color is a duller version of the males lacking the chestnut ear patches, chestnut flanks and black chest striping. With some color mutations males and females may look very similar. They are easy to sex however when you remember that all males have bright red beaks while the females beak is always orange.
Zebras also occur in a crested variety.
The ideal crested will have a perfect circular swirl of feathers on its crown. The crested zebra can be found in all color varieties. For best results when raising cresteds, do not breed two crested together. The crested mutation is dominant and only one crested parent is required to produce crested chicks. A healthy zebra finch will be active, bright and alert.
