We went out on a Nighttime tour into the forest in Tangkoko National Park.

We had the same group: our guide Roy and 2 Australians and 2 Austrians off to find Tarsiers. 

We saw a cuscus much closer and then we got to the hollow where Roy said the Tarsiers were. One popped out hung on to the side for 5 minutes before it jumped to a branch.

And then there were 3 more.
