Why do birds have beaks instead of teeth?

Quick Answer

Beaks are lighter than teeth and jaws full of heavy chewing surfaces, which helps birds fly efficiently. Different beak shapes evolved for different diets.

The Full Story

Birds lost teeth over evolutionary time and replaced them with beaks, which are lighter and easier to specialize. A beak can be shaped for cracking seeds, tearing meat, probing mud, sipping nectar, or filtering water. This flexibility helps birds exploit many ecological niches without the weight of teeth. Fossil evidence shows that early birds and their dinosaur relatives went through major changes in skull structure over time. Beaks are one of the defining features of modern birds.
