forest animals offer another important source of protein for the machiguenga.y the men go hunting -- with bow and arrow, like their fathers and grandfathers before them. it might be easier with guns, but the park administration persuaded the hunters to do without firearms so they would not kill too many animals too quickly. the machiguenga know their hunting grounds very well. today these men are after a woolly monkey. the trees are tall here, and the branches are dense, so they don't have a clear aim. after four hours of being chased, the monkey is exhausted. it is perched on a lower branch over a swamp. the machiguenga and the park administration have made a deal -- they help preserve the ecosystem in return for certain benefits. the hunters keep a list of the animals they bag. >> basically, the idea is that communities can really have an idea about how much they are hunting and what the state of the population is in the area they are hunting. and then hopefully they can take some decisions towards managing that resource to ensure that it is there forever. >>
