Norwich Cropper
A variant of Pouter (Columba livia domestica)

Representative Pouterphoto — a dedicated image of this exact morph isn't available yet.
A British cropper-type pouter: a rounder, shorter-legged bird than the English Pouter with a balloon-like crop, often crested and feather-marked. More functional in build.
Keeper tips for this variant
Less extreme than show pouters, so most pairs rear their own young — still provide deep, secure nest bowls as inflated-crop cocks can be clumsy on the nest.
