A solitary life
All these ground-living forest dwellers, large and small, are solitary since the forest floor seldom produces sufficient leaves to sustain a large group in one area for any length of time. Further if several animals are to maintain a relationship they require some kind of communication. It is not possible to see far into the forest and signalling by sound would attract the attention of potential predators. These animals also maintain territories which they mark with dung or secretions of a gland close to the eye and rely on concealment to protect themselves from predation.
The hunters that seek them such prey are also solitary. Examples are the jaguar preying on the tapir, and the leopard (Panthera pardus) preying on the duiker. A wandering Brown Bear (Ursus arctos) will eat most things including a small antelope. The smaller hunters such as genets (Genetta species), jungle cats (e.g. Felis chaus), civets (e.g. Viverra species) and weasels (e.g. Mustela) prey on small rodents as well as birds and reptiles.
