Birds have no teeth. And then what it eats goes to the muscles and stomach, and grinding it is like a tooth, and it eats sand and stones to help grind it.

Eating rocks seems to weigh about the same as teeth, so I think"In the process of evolution, primitive birds lost their teeth. Because it is possible to reduce the weight of the body. If you have teeth, you need a strong mandible to hold them in place.

Why are the beaks of birds diverse

As a result of living in different environments, the birds' beaks have also undergone adaptive changes as a feeding tool. For example, the flat beak of a duck is suitable for filtering aquatic plants in water, and the hooked beak of an eagle is good for tearing apart prey, etc.

This bird is called the pelican. Pelicans are large migratory birds. The mouth is flat and elongated, with a hook at the apex.

In the process of evolution, the wings of birds evolved into the wings of the high hail tree, which took on the function of flying, and the beak of the bird had to do more things to survive. In addition to eating, the function of the beak is often to fight, build a nest and take care of its own feathers, so birds must also evolve a beak that adapts to environmental changes in their own evolution.

Birds have a variety of beaks, and most of them are designed to catch prey in their own environment.
