Chequered
A variant of Ice Pigeon (Columba livia domestica)

Representative Ice Pigeonphoto — a dedicated image of this exact morph isn't available yet.
Ice ground overlaid with a dark chequer pattern across the wing shield instead of simple bars, derived from the checker wing-pattern allele.
Keeper tips for this variant
Aim for even, sharply-defined chequering — muddy or uneven checks on the pale ice ground stand out badly to a judge.
