RAMPHASTIDiE. 



95 



The Ramphastidae all inhabit the southern hemi- 

 sphere of the globe : they are known by their enor- 

 mous beak ; they fly in small troops, and are nou- 

 rished upon fruits and insects, and during the period 

 of incubation they devour eggs and small birds. They 

 represent the Hornbills of the old world.
