The Nun was once known as the Dutch Shell Pigeon. As will be apparent, the
name comes from its head markings, which bear a resemblance to the religious
garb a nun wears. The tail and the ten most outward flight feathers are the
same color as the head. British fanciers played an important part in creating
the Nun as we know and you see it here today..
Ed Schubert bred this champion red Nun.

Each breed is judged on its specific desirable characteristics. These generally include markings, size, and shape, but may also include the pigeon's carriage, demeanor, and overall impression. For instance, a perfectly marked Voorburg Cropper that was shy would lose to one that might have a slight imperfection in markings, but was very responsive to the judge. Voorburgs are supposed to show themselves off. In breeds with very distinct markings, like this Nun, a few colored or white feathers out of place can detract severely from the overall impression
