Even though I had been engrossed in building notes in the endemic birds that I could listen to and see, Shirish and his scholar cautioned me about 9-10 “wild” elephants that occupy this 134-sq-km island. Although we noticed dung piles in several places, we didn’t face any elephants. A further animal introduced through the British inside the Andamans (including on Interview Island) was the chital or noticed deer (Axis axis). We listened to a handful of chital phone calls and saw dung pellets in several places but did not see the animal.
