RESTING BEHAVIOUR POSTURES OF INDIAN SPOT-BILLED DUCK (Anas poecilorhyncha)

This study presents different resting postures of Indian spot-billed duck. Four resting postures were observed namely: Sleep posture, Rest-sleep posture, Rest posture and Unipedal posture. In every resting posture, ducks remained vigilant which is crucial for its survival from predators. Vigilant actions such as “peeking” and “pseudo sleep” were also observed. Sometimes, lotus leaves were used for sleep. Invariably, resting period was high during mid-day compared to morning / evening.
