The Flying Rhino is not a prehistoric dinosaur but it does look like one, with its large, mad staring eyes.
The rhinoceros hornbill is the largest hornbill, aka the flying rhino. It has one of the largest and most impressive casques — a feature they share with hadrosaurids from more than 60 million years ago.
The flying rhino and other hornbills practise one of the most ingenious nesting rituals of any bird. When the female is ready to lay her eggs, she goes into a hollow tree cavity and helps the male seal the entrance with a paste made of fruit, mud, and feces. The pair leaves only a small slit, through which the male feeds the female (and later the chicks) for the next four to five months. The female keeps the inside of the nest cavity clean by pushing uneaten food and fecal matter back out through the same slit. When the chicks are about three months old, the female breaks herself out…and both parents and offspring collaborate to re-seal the chicks inside for another three months. Both parents continue to care for the chicks until they are old enough to break out of the nest on their own and fly free.
The cry is a hollow honk. The Rhinoceros Hornbill’s casque is an amp! The cry of the hornbill is amplified so they can be heard all throughout the rainforest. This feature has led paleontologists to believe that maybe harosaurs used their fancy head crests in the same way. So when you hear a Rhinoceros Hornbill’s echoing honk from somewhere out of sight, you might just be hearing the voice of this great bird’s inner dinosaur. They call only to defend their territories from other breeding pairs. It is warning, so you have been warned what Cry of the Flying Rhino is about!
