German Nun

Bird

German Nun (German: Deutsches Nönnchen) is a breed of fancy pigeon bred by German pigeon fanciers. German pigeon-breeders have had great success in breeding German Nuns, which originated in the early seventeenth century. These birds are also widespread among the pigeon-breeders of Russia, where they are called Cross Nuns. The breed got its name Nun from a colored cap on its head, and Cross from the colored tail and colored primary wing feathers, which resemble a cross during the pigeon's flight. The rest of the feathering is white.
