Video by joelsartore | The keel-billed toucan is easy to recognize throughout the forests of Central and South America thanks to its massive, colorful bill. Though the bill can grow to nearly six inches (15 cm) in length, it's actually quite light. That’s because it is no more than hollow bone covered in a hard protein called keratin.
