Representative Booted Bantamphoto — a dedicated image of this exact morph isn't available yet.
Self-black variety with a beetle-green sheen contrasting the long white-or-black booted feet.
Keeper tips for this variant
Provide low roosts so a heavily booted bird can perch without damaging foot feathers; keep out of harsh sun to protect the black sheen.
