The Rhinobill is the descendent of ground-hornbills. Rhinobills have two horn-like projections on their beak that are similar to those of rhinos (hence their name). At birth, a Rhinobills horn-like projections start as small bumps that are barely noticable. As the Rhino bill gets older the horn-like projections grow longer.
Rhinobill use these horn-like projections as weapons or to knock friuts out of trees by ramming their horn-like projections into a tree. Like their ancestors, rhinobills are omnivorous. Their diet consists of fruits that they knock out of the trees by ramming into them, insects, small reptiles, small amphibians and small mammals. The Rhinobills fill the niches of large African mammals such as rhinos, elephants, hippos, wildebeests, and buffalos.
Rhinobills have formed a symbiotic relationship with small mammals that cling on to rhinobills and feed on the parasites. These small mammals sometimes even hitch a ride on rhinobills. The symbiotic relationships between these small mammals and rhinobills is very similar to the symbiotic relationship between rhinos and oxpeckers.
