Toucan
Toucans are known for their huge beaks, which can grow larger than their bodies. The beak may also be used to cool the bird off. They use their beaks for reaching over and plucking fruit from branches of trees. The bright colors (usually orange) on the beak may help the toucans to recognize each other, and to scare off other birds. The structure of their beaks consists of a keratin exterior and a bony foam interior. The beak is loaded in bending and foraging and fencing activities, although it has a low compressive strength.
