==Description==
The South Georgia shag is medium-sized, about 29.5 inches in length.  Males are larger than females.  The undersides are white from the chin and throat to the lower belly.  Upper plumage is black with a slight bluish or green-bronze tinge, and a single white horizontal bar on the upper wing coverts.  A slight tuft of feathers on the head gives it a crest; a small mass of yellow-orange, warty caruncles at the base of the upper beak and the blue eye ring are the only other colors.
