English Short Faced Tumbler
A variant of Tumbler (Columba livia domestica)

An ancient exhibition breed bred for an extremely short, fine head and tiny beak, giving a delicate doll-like face. Centuries of selection for the cobby, short-faced look pushed it far from the wild rock dove form.
Keeper tips for this variant
The reduced beak means most pairs cannot feed their own squabs reliably — keep robust foster/feeder pigeons (or hand-feed) so chicks don't starve.
