White
A variant of Zebra finch (Taeniopygia guttata)

Representative Zebra finchphoto — a dedicated image of this exact morph isn't available yet.
A recessive mutation producing an all-white bird that still has a normal dark beak and (in males) cannot show the cheek/flank pattern.
Keeper tips for this variant
Heavy selection for pure white has weakened some lines, so buy robust, well-sized whites and outcross periodically to coloured birds to keep vigor.
