Many mammals roam through the rainforests, often ranging hundreds or even thousands of miles, while others stake a territory and stick to it.  Troops of Howler Monkeys migrate through, sometime staying for days in one place, or just as frequently stopping by for a quick snack while disturbing the peace with their raucous calls.  Sloths move around, too, albeit at a much more measured and quiet pace.  Whether providing habitat and needed food sources for mammals that stay in one place or just use the wildlife corridor highway to move to another space, small rainforests play a critical role to these amazing animals.
