By the midday heat, the Green-billed toucan has retreated to a shaded area of the treetop. Its huge but lightweight beak serves among others things as the regulator of its heat balance. Depending on the ambient temperature, the blood that flows through its bill can be cooled or heated. This natural air conditioner allows the Toucan to stay cool on the hottest days here in the jungles of South America.
