GBOUP OF HORNBILLS, 



Hornbill {Buceros cristatus), and that on the right is the Two-horned Hornbill (Buceros 

 hicornis). The smaller species at the bottom is the Woodpecker Hornbill {Buceros Pica). 



Peehaps the greatest development of beak and helmet is found in the Khinoceeos 

 HoENBiLL, although there are many others which have these appendages of great size, as 

 may be seen by referring to the group of Hornbills.
