White-headed capuchin
The diet can vary between the rainy and dry season.  Some tribes will eat many types of fruits in the rainy season  and during the dry season, they eat mostly  insects, ant and wasp larvae and vertebrates.  Access to water can also be a problem during the dry season.  The white-headed capuchin likes to drink every day. In forests where water holes dry up, there can be competition between troops over water holes.
