Chestnut-flanked white (CFW)
A variant of Zebra finch (Taeniopygia guttata)

Representative Zebra finchphoto — a dedicated image of this exact morph isn't available yet.
A sex-linked mutation that whitens the body but retains the chestnut flank, cheek, and tear markings, giving a clean white bird with crisp accents.
Keeper tips for this variant
CFW markings dilute easily if outcrossed carelessly; breed CFW to CFW or known splits to preserve the bold flank color, and keep nutrition high to maintain it.
