Guojiang Cormorant

The Guojiang Cormorant or Syltör Cormorant, Nannopterum littorum, is a species of aquatic diving bird native to Syltör. It has a black body with dull brown wings, and yellow markings around its pale beak. Males have white tufted "eyebrows" during the breeding season.

The bird is known for being tamed by Aurlûnoren Humans, and more recently Celestial Elves, who use them to assist in fishing. The practice dates back to the Guren kingdom of Yi'yen several thousand years ago, and is still practiced today in some rural villages in Nir Province.
