The Duck. 



77 



The duck's bill is broad and flat. The duck 

 has no teeth ; but there are little notches on the 

 edges of the bill. This bird is very fond of gather- 

 ing some of its food under the water. These 

 notches are used to drain the water from the 

 food it gets in this way. 



Have you ever thought that the flying and 

 swimming birds use their tails as rudders ? 



The flying birds steer themselves through the 

 air by their tails ; the swimming birds through 

 the water. 



Do you know 

 the names of other 

 birds belonging to 

 the family of swim- 

 mers ?
