- There are over forty species of toucans found in the tropical rainforests of Central and South America.
- Their bright colorful markings provide them with excellent camouflage in the rainforest.
- Toucans have larger bills, in comparison to the size of their body, than any other bird in the world.
- Their large bill helps them keep cool in the hot environment in which they live. This adaptation is one of the best heat regulating systems in the entire animal kingdom. Arteries in their bills expand when the bird gets hot; and release heat.
- Their bill is big and may look heavy but it is actually extremely light. It is made of a spongy substance called keratin. Nails and hair of many mammals (including humans) is made of keratin.
