Abstract:

Behaviour is the range of actions and mannerisms made by individuals in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the physical environment. Studying the behaviours of the Lion-tailed macaque (LTM) is especially pertinent because it is highly endangered. Of worlds 21 species of Macaques, lion-tailed macaques (Macaca silenus) are one among the most rare species. The Lion-tailed macaque (Macaca silenus) is a flagship species for the many endemic and threatened animal of the Western Ghats, Southern India, and a high priority species in captive propagation. Focal-animal sampling technique was adopted for recording the Active and Passive behaviour of LTM. The following behavioural observations in relation to time spent on Active (Moving, Social, Grooming, Foraging) and Passive (Resting or Sleeping and Sitting Simply) preference are studied with the aim to assess the diurnal active time spent on behavioural patterns of capped lion-tailed macaques. Of 340 hrs of observation (170x2), 170 hrs for On-display and 170 hrs for Off-display were observed. The On-display M. silenus young male totally spent 136 hrs for active and 34 hrs for passive behaviour, the adult male totally spent 109 hrs for active behaviour and 61 hrs for passive behaviour and the older male spent 64 hrs for active and 106 hrs for passive behaviour. The On-display M. silenus young female totally spent 123 hrs for active and 47 hrs for passive behaviour, the adult female totally spent 99 hrs for active behaviour and 71 hrs for passive behaviour and the older female spent 58 hrs for active behaviour and 112 hrs for passive behaviour. The Off-display M. silenus young male totally spent 127 hrs for active and 43 hrs for passive behaviour, the adult male totally spent 97 hrs for active behaviour and 73 hrs for passive behaviour and the older male spent 61 hrs for active and 109 hrs for passive behaviour. The Off-display M. silenus young female totally spent 119 hrs for active and 51 hrs for passive behaviour, the adult female totally spent 91 hrs for active behaviour and 79 hrs for passive behaviour and the older female spent 56 hrs for active behaviour and 114 hrs for passive behaviour.
