A variant of Domestic goose (Anser anser domesticus)
Representative Domestic goosephoto — a dedicated image of this exact morph isn't available yet.
A slim, upright goose with a prominent forehead knob, in white or brown, descended from the swan goose. The best laying goose and a vocal 'watchdog'.
Keeper tips for this variant
Loud and alert — great natural alarm/weeder geese, but the knob can frostbite in hard winters, so provide draft-free shelter in cold climates.
