NATATORES — ANATID^E — ANAS. 339 



This is the most beautiful of all the clucks known ; the only one approaching it being the 

 A. galericulata, or Mandarin Duck of China, which indeed it strongly resembles. Its popular 

 name of Wood Duck is derived from the fact that it makes its nest in hollow trees. During 

 the summer only is it seen in this State, migrating southwardly with the cold weather. It is 

 easily domesticated, and one of my neighbors raises numbers of them annually. Its food 

 consists of acorns, seeds of aquatic plants, and insects. It breeds from Mexico to the 

 Columbia river, and eastwardly to Nova-Scotia : its eggs yellowish white. It has been 

 found from 19° south to 54° north latitude. Peculiar to America.
