 lowing morning and for several days after.  They very rarely fly in your  
 presence, and  they leave the ponds at night.  If forced  to rise on  wing,  
 they run paddling on the water for several yards before  they rise, and  
 fly several times round a pond of  thirty or forty  yards before  they attain  
 the level of the tree-tops, for  they never fly through  the woods.  When  
 once high in the air,  they move in a direct course and with speed, towards  
 some other  pond or the nearest river. I do not remember  to have ever  
 met with a bird  of  this species on a narrow creek or bayou, or on muddy  
 waters; and on the Ohio's  rising I have observed that  they abandon the  
 river and betake themselves  to the clear ponds of the interior.  
 By  the  1st of October, scarcely any difference can be perceived  between  
 the young and the old birds with respect  to plumage, only the latter  
 have the under surface of the wings  still dashed  with  the reddish colour  
 of the summer dress. I am not able  to say from observation how  
 long the  young are in  attaining  maturity;  but European writers assert  
 that  they take three or four years.  When these birds leave the southern  
 waters about the beginning of  April, the old already shew their summer  
 head-dress, but seldom have it so perfect as is represented in the plate.  
 The food of  this species consists of fishes, aquatic  insects, and small  
 reptiles, together  with the seeds of water plants.  Dr  RICHARDSON  states  
 that these birds are abundant in all the secluded lakes of the mountainous  
 districts of the fur countries, and adds that their nests are formed of a  
 large  quantity of grass, placed among reeds and carices, and rise and fall  
 with the water. Mr  YARRELL  hasjkindly furnished me with specimens  
 of the eggs, which are generally four, measure two inches and a quarter  
 in length  by one inch and a half, have an oval form, and a smooth surface, 
  of a uniform  yellowish-white colour.
