io8 Birds Every Child Should Know

whatever conditions they meet. How wonder- 
fully that saucy little gamin, the English spar- 
row, has adjusted himself to this new land! 
Members of the more aristocratic finch and 
grosbeak branches of the family, however, who 
wear brighter clothes, pay the penalty by de- 
creasing numbers as our boasted civilisation 
surrounds them. Gay feathers afford a shining 
mark. Naturally grosbeaks prefer to live 
among protective trees. They are delightful 
singers, and so, indeed, are some of their plain 
little sparrow cousins. 
All the members of the family have strong,

gizzards, like a chicken’s, to grind them fine. 
These little grist-mills within the birds’ bodies

seed. The sparrow tribe, you will notice, do
