 The East Indian butterfly, shown in the middle front 

 of the case, is one of the most striking illustrations of

Animal Life : Securing Food. — The case on the right 

 shows some of the ways animals have of getting food. 

 On the top shelves are a series of birds, showing 

 how the different classes of birds are adapted to dif- 

 ferent kinds of food or different methods of obtaining 

 it. Notice that the woodpecker has not only a stout 

 bill for digging the worms and grubs out from under 

 the bark of trees, but his feet are specially adapted - 

 for clinging to the perpendicnlar face of the tree. 

 The kingfisher has a large bill for catching fish. The 

 hawk, as a type of the birds of prey, has not only a 

 hooked beak for tearing his prey, but stout claws 

 for seizing it. The duck has webbed feet for swim- 

 ming and the flat spoon-like bill for digging up the 

 mud. Notice the long, slender, curved bill of the 

 humming bird for getting the nectar of flowers, and 

 the medium-sized bill of the blue bird for worms and 

 seeds.
