Pteroglossus erythropygius

Pteroglossus erythropygius, Pale-mandibled aracari, is a medium-sized climbing bird.

The soft-billed Tucan is also the noisiest of the forest birds, producing loud rumbles, trumpets, and screeches. Its nest is built in a hole high in a tree. When eating, always peck the food with the tip of the mouth first, then tilt the neck, throw the food upward, and then open the big mouth to accurately put the food into the throat, without having to go through the long mouth and spend time in the process of "swallowing". It is omnivorous, feeding on fruits, seeds, and insects, and sometimes raiding the nests of small birds, eating eggs and chicks.

The margin of the beak is usually clearly serrated, black or ivory in appearance, and looks somewhat like a tooth. Despite its large beak, the Toucan weighs less than 30 grams. The structure of the mouth bone is very special, it is not a dense entity, the outside is a layer of crust, through the middle of extremely fine fibers, porous spongy tissue, filled with air, so that it does not feel heavy pressure.
