English Pouter

Bird

As with all breeds of domesticated pigeons, the English Pouter is descended from the Rock Pigeon (Columba livia), and has been developed over years through selective breeding of individuals with specific characteristics. It is a breed of fancy pigeon, that being a type of pigeon kept by pigeon fanciers as part of the fancy pigeon group as opposed to Flying/Sporting Pigeons or Utility pigeons. The Pouter is long limbed with an enlarged crop, and overall a large body.
