Dalmatian pelican (Pelecanus crispus).
The birds with the largest beak are the pelicans.
They are also one of the largest flying birds on Earth.
The bones of the huge beak, as well as the entire skeleton, have numerous cavities filled with air.
This makes them lightweight without reducing their strength.
Under their lower jaws, the pelicans have a huge leather bag that holds fish caught.
Have you ever seen pelicans in the natural environment?
