This handsome species is common inland upon the streams 

 and ponds, but I have seldom met. with it upon the salt water. 

 The birds are swift in flight, graceful upon the water, and active 

 divers. Their food consists of small fishes, crawfish, frogs, and 

 all forms of insect life. 



Their nests are placed in shallow holes and trough-like cavi- 

 ties in trees near the streams, and are lined with grasses, leaves", 

 feathers and down. Soon after the young are hatched, the 

 mother carries them by the neck or wing to a secluded retreat 

 at the waters edge. Eggs six to ten, 2.10x1.72; pure ivory 

 white, with a few neutral tints; in form, ovate to rounded ovate.
