Representative Sebastopol Goosephoto — a dedicated image of this exact morph isn't available yet.
Gray-patterned or saddleback-marked Sebastopols, combining the curled feathering with gray coloring over the back and head. Uncommon and prized by breeders.
Keeper tips for this variant
Markings are hard to fix in a curled-feather bird, so select breeders carefully — and as with all Sebastopols, never house them without dry shelter, since curled feathers shed rain poorly.
