Great Indian one-horned rhinoceros can communicate very systematically with other rhinos in spite of being solitary in nature. Having poor eyesight they rely more on their acute sense of smell and on auditory signals. For that reason, they can emit ten types of vocalisations every one of which has a separate meaning. By sniffing dung piles they can understand who had defected there before, what are their reproductive status and can understand the details of their age and sex categories. The sounds emitted during aggression and foreplay with the opposite sex are quite distinguishable. In 38.5% cases, the cows were the first defecators and next followed by the bulls. Only in 18.3% of cases, the opposite was true. Before and after defecation they broadcast some communicable signals like, earth scrapping over their own dung, dung scrapping, foot-dragging etc. which are very much meaningful. Recently discovered hidden chemical clues in the dung piles are also very informative to them. The least important communication system in them is the visual and tactile signals.
