HOW BIRDS USE THEIE BILLS. 



The birds do not have hands, 

 but they have something' that 

 answers just as "well. Their bills 

 are as useful to them as your 

 hands are to you. 



They are not all made alike, or 

 used in the same way. The duek 

 has a very queer bill. It is made 

 so because this bird has to find its 

 food under water. It cannot see 

 what it gets, and must feel in- 

 stead. 



So this bill is tilled with nerves 

 for the purpose. It has a I'ow of 

 little points, too, all around the 

 edge, something like teeth. But 

 how does the duck use it? Let 

 us see. 



When searching for food it 

 thrusts this bill down, and brings 

 it up full of mud. ^N'ow, in the 

 mud are the very things the bird 

 lives upon.
