Oriental Pied-Hornbills
Ever wondered what that huge horn-looking structure on the top of their beak might be? It is called a casque! As massive and heavy as it looks, it is actually hollow inside. The casque signifies their sexual maturity and you can identify their gender by the size of it. Males tend to have a bigger casque than the females. It is also said to make their calls louder. That's all folks! Till the next sighting :)
