Measuring 63.5 cm (25 in.) in length, the toco toucan is the largest of all toucans. Its black body and white throat are overshadowed by its most recognizable trait: a large colorful beak.
Furthermore, recent research has concluded that toucans regulate body temperature by adjusting the flow of blood to their beak. More blood flow means more heat is released. When toucans sleep, they tuck their beak under their feathers to keep them warm.
Toco toucans also use their beaks to pluck and peel fruit, their main source of food. In addition, the beak houses a flat tongue of the same length, which helps the toucan catch insects, frogs, and reptiles. Toco toucans also occasionally eat the eggs of other birds.
