Conservation breeding programmes as an essential tool for conservation of endangered species require a sound knowledge on behaviour of the species. At present time, knowledge of behaviour and biology of Indian pangolins is inadequate and inconsistent. During the present study, an ethogram was developed based on the behavioural observations of seven Indian pangolins (Manis crassicaudata) at Pangolin Conservation Breeding Centre, Nandankanan Zoological Park, Odisha, India, between February 2012 and January 2013. A total of 27 behaviours of seven distinct behavioural categories (stationary body positions, locomotory patterns, maintenance behaviours, explorative behaviours, defensive behaviours, reproductive/social behaviours, and others) were described and illustrated. The results offer a consistent frame of reference for further studies on behavioural patterns of Indian pangolins. Besides, these preliminary observations could be useful in management and breeding of the species in captivity. 1. Introduction Indian pangolin (Manis crassicaudata; family Manidae; order Pholidota) is one of the eight living species of pangolins of the world. They are toothless mammals with 11–13 rows of large overlapping horny scales, long protrusible tongue, and prehensile tail with a terminal scale on its ventral side [1, 2]. They are solitary, fossorial, nocturnal, and insectivorous. Indian pangolin occurs throughout peninsular India [3, 4]. Its range extends as far west as Pakistan, east to West Bengal (India) and Yunnan (Southwest China), south to Sri Lanka, and north to Nepal [5]. Their populations are increasingly under threat throughout their range due to domestic and international demand for live pangolins and their skin, scales, and meat. The biology of Indian pangolins particularly low reproductive rate and a wide distribution make them vulnerable to overexploitation [6]. Captive breeding programme, which is essential for the conservation of the species requires detailed knowledge about the behaviour of the species. The Indian pangolin is a poorly known species. Little effort has been devoted to understanding its biology, ecology, and behaviour, perhaps due to nocturnal and secretive habit of the species. Available published information on Indian pangolin is primarily from natural history observations, rescue reports, reports of illegal trade, and captive studies. Many practical questions remain unanswered because of incomplete information on ecological and behavioural biology of the species. Comprehensive knowledge of pangolin behaviour will be central to assess
