USE OF THE KEYS. 



If you are a beginner with a bird to identify, and do not know the 

 orders into which birds are divided, go first to the Key to Orders, 

 pp. 1,2. If your bird is a plover, you may not be sure whether it is 

 classed with the water or land birds ; so begin with the Key to 

 Water Birds. This key, as all others in the book, is dichotomous, 

 that is to say, at every step the birds are divided into two classes, 

 which have or have not a given character — birds are black or they 

 are not black, they have crests or they have not crests, their feet are 

 webbed or their feet are not webbed. At each step of the key a 

 number and its prime are used to set apart the two classes. In the 

 case of the Key to Orders of Water Birds the first two classes are 

 birds which have 



1. Feet fully webbed.
