Also described as the rainbow-billed toucan, these birds are gregarious in both coloration and behavior. Known for croak-like calls that can be heard a mile away, keel-billed toucans like to be social and playful and are considered one of the noisiest birds in the jungle. While this South American bird reflects the effervescence of his native land, his aerial acrobatics cannot be described as having any Latin rhythm. Keel-bill toucans are notoriously awkward fliers and prefer to hop- perhaps to better show off their lovely blue pedicure.
The hallmark of the toucan is their colorful bill and yet the origin of its unusual size (it can be almost as big as the bird) and color are not fully understood. Some experts propose the beak is used for thermoregulation. Others theorize that the beak may intimidate smaller birds or it allows the toucans to exploit a feeding niche by being able to pluck fruit off of branches too small to bear their weight. What is known is that while the bills appear heavy- they are actually hollow and lightweight and made out of thin rods of bone and keratin.
