Why does a parrot have a strong beak?

Parrot beaks are extremely strong, and one of their primary tools for protecting themselves. The same beak strength allows him to enjoy a varied diet - instead of just eating small or soft foods, he can easily bust open nuts and seeds that have hard outer shells. A parrot can crack a shell that you would need a nutcracker to open. The beak allows them to consume hard foods as easily as they do berries.

The parrot's beak is powerful and it's precise. Parrots use their beaks to eat a variety of foods that require something other than sheer force to consume. For example, a parrot may use the beak like a surgical scalpel to remove seeds from their casings or to peel fruit.

The beak is always growing. It is coated in a hard keratin shell that continually replenishes itself, so it's always fresh. Because the shell is always growing, parrots have to wear the beak down by frequent eating and chewing hard solid foods. Otherwise, the beak can become overgrown.
