Bird Bill of Fare

Have you ever tried to eat soup with a fork or salad with a spoon? People have learned to use the utensil that works best for different foods they are eating: soup—spoon, salad—fork, and even fries—fingers. Birds do the same thing, only instead of using utensils they use their beaks. Birds have very different types of bills depending on what food they primarily eat. There are beaks for snatching bugs, spearing fish, probing flowers, cracking seeds and tearing meat. All of these beaks have evolved to fit the birds’ diets perfectly.
Seed eaters and bug eaters have similar beaks. They are strong enough to crack seed shells, and thin enough to capture bugs from tight spaces. The size of the beak varies greatly among these birds, ranging from the small, dainty beak on this Eastern Towhee to enormous toucan beaks used for feasting on fruit and insects.
