FAMILY ANATIDA).—THE SWANS, GEESE AND DUCKS. 
Of the family Anatidze we have in Ontario a very large representation, for 
_ birds of this group are generally most numerous in the northern portions of the 
earth, hence Ontario, on account of her great extent northward toward their 
breeding grounds, comes in for a large share of them. The representatives of this 
S: family of birds in North America may, for convenience, be divided into three 
groups, viz. :— | 
The Cygninz, or Swans. 
The Anserine, or Geese. 
The Anatinz, or Ducks. 
=r Of the sub-family Cygninz or swans there are two varieties which inhabit 
America, the Olor Columbianus or Whistling swan, and the Olor Buccinator or 
_ Trumpeter swan.
