NUN 



The striking feature of the Nun is the great contrast 

 in color ; the body and shoulders being pure white with 

 face, bib, and tail black. It is the size of an ordinary- 

 pigeon, compact and graceful. Head and beak are like 

 a flying Tumbler but in proportion are hearvier. The 

 important point of this bird is tlie shell which rises 

 from the base of the skull extending on either side to 

 the level of the eyes, full feathered, and upright, ris- 

 ing perpendicularly at back of head. The flight's are 

 black with nine or ten feathers each; the eye, pearl, 

 with the cere fine, small and dark colored.
