The Dun-bird, Looby or Dun Diver, is rather rare on the coast of this Slate. It is a boreal 

 species, breeding in high northern latitudes, descending along the whole coast of the United 

 States in the winter, and penetrating into the interior. It is frequently called the Saltwater 

 Teal. Its food consists of marine and freshwater plants and seeds, and its flesh is said to be 

 very savory. Its history yet incomplete.
