9.3.3.1. Bird beaks

Types of bird beaks

The beaks are a typical structure of some vertebrates, such as tadpoles, reptiles when they  hatch, turtlesplatypuses and birds.

Birds do not have teeth, but they do have a beak, which is much lighter than the teeth, so it does not hinder flight. The beak has two holes, which are the nostrils, through which the breathing air passes. With the beak, the birds cannot chew, so they swallow their food whole. The gizzard is responsible for grinding food.

They not only use their beaks to eat, but also have other uses, such as grooming, killing prey, fighting, foraging, courting their mates, or feeding their young.


Carnivorous

Carnivorous birds have a curved, hook-shaped beak, which allows them to tear off the meat.

Examples: eagles, falcons, vultures, owls, barn owls, tawny owls.
