 Mergus Merganser,  Linn. 
 Le Grand Harle. 
 P ke-eminently  distinguished  by the  breadth  and boldness  of  its colouring,  and the  delicacy of some of  its  
 tints,  the Goosander,  both  from  its beauty and  its superiority of  size,  is  entitled  to rank as  the  finest of  its  
 genus ;  admirably adapted for diving,  it possesses great power  and agility in  the water;  its flight also, when  
 once fairly on the wing,  is strong and rapid. 
 Its  native  locality appears  to be  the  northern  regions o f  the  continents of Europe  and  America, where,  
 among large and unfrequented lakes, it finds an asylum  and breeding place:  from these,  its summer haUnts,  it  
 migrates southwards  on the approach of the severities of winter,  seldom appearing in  our latitudes unless the  
 season  indicates  an  extremely low  temperature  in the  Arctic  circle;  at such  times  it frequents  our shores  
 and  unfrozen  lakes,  either in  pairs or  in small  flocks of  seven or  eight:  but the  extensive inland  waters  of  
 Holland and Germany appear to be its favourite  place o f resort. 
 The form of the body is long and compressed;  the total length  twenty-six inches;  the weight four pounds. 
 Beak  red  on  the  sides,  darker  above,  edges  serrated;  armed at  the  end  with  an  abruptly hooked  nail.  
 Head ornamented with  slender elongated hair-like feathers, forming a voluminous crest of a rich glossy black  
 with green reflections, which colour is continued half-way down the neck, where it terminates abruptly.  The  
 back and scapulars  of a fine black; wing-coverts and secondaries white.  Quills blackish-brown;  rump and tail  
 grey,  the sides  irregularly marked with  fine waved freckled darker lines ;  tail-feathers eighteen.  The whole of  
 the  under surface of the body of a delicate yellowish  cream-colour.  Legs placed  very far back.  Tarsus and  
 toes  of a  rich  orange-red ;  interdigital membrane rather darker. 
 The  trachea  presents  two  enlargements  o f  the  tube  before  it  enters  the  labyrinth  or  inferior  larynx,  
 which consists of two irregular cavities divided from  each  other by a membranous partition. 
 The  female is  considerably less  than  the  male,  and  differs  from him  not only in plumage  but also  in  the  
 anatomical  structure of the  trachea, which  wants  the enlargement  both of  the tube  and  the  bony labyrinth.  
 The beak,  irides  and  feet  are less  brilliant in colour.  Head,  neck  and crest  rufous brown ;  chin white;  the  
 uppersurface of the body uniform dark ash grey; the under part lighter with a tinge of cream-colour. 
 These  differences in  the  female,  connected  with  the similarity of  plumage characterizing  the young  males  
 of  the year,  (which are only to  be distinguished  by the masculine structure of  the trachea,  and rather larger  
 size,) have induced early writers  to consider  them as a distinct species,  to which  they have applied the name  
 of Dundiver;  an error corrected by more recent observation. 
 Its food consists of fish,  small Crustacea,  and molluscous animals.  Its flesh is rank and unpalatable. 
 The female is said to lay twelve whitish eggs,  but the  nidification of this bird is little known. 
 Our Plate represents  a male and female in full plumage,  two  thirds of the natural  size.
