Shirish as well as forest Section experienced numbered the caves. Shirish advised me that white-bellied or glossy swiftlets (Collacalia edible nest swiftlet esculenta) and edible-nest swiftlets roost in the same caves, but shiny swiftlets return prior to dusk as they cannot echolocate (navigate using reflected audio). We sat in the forest inside the fading mild, slightly far from mouth-one of your swiftlet cave. His college students and the opposite swiftlet protectors went to gather knowledge from mouth-two. Shirish counted the number of shiny swiftlets getting into the cave — the undertaking designed harder by some people traveling out and returning. This counting was a prelude. Soon it was time to the grand finale — the function for which I had come to the Andaman Islands again.
