We sat during the forest during the fading light, a little bit from mouth-1 on the swiftlet cave. His learners and one other swiftlet protectors went to collect facts from mouth-2. Shirish counted the number of glossy swiftlets moving into the cave — the endeavor built more difficult by some folks traveling out and returning. This counting was a prelude. Soon it was time for your grand finale — the function for which I'd arrive at the Andaman Islands all over again.
