Abstract

The social behaviour of the nocturnal prosimian Loris tardigradus lydekkerianus in its natural habitat was studied for 21 months in a scrub jungle in Dindigul, southern India. A total of 22,834 scans were collected during 2,656 hours of observation on identified and unidentified lorises. Social interactions were observed between individuals of all age-sex classes, both during the night and at dawn, when the animals met to sleep together. The majority of aggressive encounters between individuals occurred in territorial and mating contexts. Individuals also communicated with each other through chemical and vocal signals. Adults and sub-adults of both sexes were observed to immigrate into the study area, leading to social interactions with resident individuals.
