Cool, thanks for the information! I know you can see sportive lemurs during the day roosting, but they tend to be nocturnal animals, so It would be a more interesting experience to see them at night, right? I think also seeing animals at night is a lot more exciting in any scenario.Yes, looking for mouse lemurs at night works, but for sportive lemurs, the best way to see them is to find the resting spots during the day (or be shown these spots by the local guides). Obviously, if you were there for a significant period, then nocturnal observations become more of an option.
The other thing to look out for at night is resting chameleons; easier to detect small arboreal species sleeping on the ends of narrow branches.
