The Spectacled Caiman (Caïman à lunettes), can be observed at night. This is a traditional night excursion made at the Kaw swamp.
We embarked on a pirogue from the "floating camp" at 20:30 sharp in the complete dark. Our guide, Gilbert, had only a light halogen torch mounted on his head. He was standing at the rear side for piloting the pirogue. As the boat was moving, he was regularly sweeping the river bed from left to right and right to left with the beam of his lamp. The trick is that, in the complete dark, the eyes of the caiman strongly reflects the light when on the surface of the water. With such a technique we were able to approach a young caiman after 15 minutes. Great!
We continued our way for further observations. Then, after another evidence of the presence of a caiman, Gilbert re directed swiftly the pirogue in right direction without engine power to reach the targeted place. The boat slided silently in the complete dark toward the flooded bank while he was getting to the front. All passenger lights were switched off according to his instructions, but suddenly we just eared a noise as if someone fell in the water...
No panic, Gilbert just told us that we can now switch on our torches as he just caught the caiman to show us.
