Cool Fact:

When these hornbills are ready to breed the female finds a cavity, or hole, in a tree where she lays her eggs.  Her mate closes the opening to the nest with mud, leaving a small space where he can pass food to the female and the chicks.  The whole family depends on the dad until the chicks are old enough to fledge and leave the nest

Conservation Story:

The Greater Hornbill is threated due to habitat loss.  People clear forests to make space for more farmland and new villages.  As the older forests are cleared there are fewer trees that have the cavities these hornbills need to raise their young.  But people donít want to see the hornbills just disappear. 

What is being done now?

Habitat for hornbills and many other species is being preserved in places like Nameri National Park and Kaziranga National Park.

What should be done in the future?

More natural forests should be protected for the hornbill.
