Spix's disc-winged bats (Thyroptera tricolor) can be seen at Overbridge if you are lucky. These bats roost in leaves of the Heliconia plant at the stage where the leaf is not fully unfurled but in a cone shape. When walking on the wanderway, keep your eyes open for such leaves. Carefully have a look down ones that are still cone shaped and maybe you will be rewarded with seeing a small colony of very cool bats. As always, keep disturbance to a minimum but enjoy an awesome bat-watching experience.
