WHAT IS A DOMESTICATED ANIMAL? 
few words upon the subject of domestic birds may be worth 
notice. In this country we have but few species that may 
be regarded as domesticated. They consist of various 
breeds of ducks, geese, fowls, turkeys, pigeons, doves, and 
a few small birds. Swans have not been included, although 
they breed freely in captivity; nevertheless they have 
undergone no marked variety, they retain their wild dis- 
position and habits, and unless they are pinioned or their 
wings mutilated they are liable to fly from captivity ; hence 
it appears they retain sufficient of their original wild habits 
as to place them on the border or margin of domestication.
