WHOOPING SWAN. 



Gardens of London, and one year wlien the cygnets, only a few- 

 days old, were sunning themselves on the margin of an island

 of the young birds. In an instant the old male Whooping Swan

 held the bird there until it was drowned. 



THE BEWICK SW^\N. 



Cygiiiis bcii icki ( Yarr.). 



Closely related to the Whooping Swan and for a long time 

 confused with it is the Bewick Swan. Its habitat is much the 

 same as that of the former bird, except that it has never been 

 found in Greenland. Its breeding grounds are more to the east-

 winters. In appearance it is considerably smaller than the 

 Whooping Swan, and the yellow on the bill covers only the lores 

 and the basal third of the upper mandible, not extending as far 

 down as the nostrils. 



The call note is a loud, deep whistle, very unlike the notes of
