Some of the members of this group are known to all; indeed,

created in your mind an idea that bird study is very simple — 
that you know at least one of each of the groups of birds. One 
further advantage of bird study is that so few birds are found in 
any district. Thus, only 880 birds have ever been recorded 
from Australia, whereas there are over 9,000 kinds of native 
flowering plants, not to mention non-flowering plants. In very 
few districts could a list of 100 different kinds of birds be compiled 
in one year.

because they have no common names, that does not apply to birds, 
for bird-lovers have given a simple name to each bird. Even 
children, therefore, can talk definitely and exactly about the differ-
