Author(s): Purnima Devi Barman, DK Sharma
Abstract: The Greater Adjutant Stork Leptoptilos dubius, rare stork, is an IUCN Red list endangered bird, has now been confined only to Cambodia and in Assam and Bihar in India. This bird is facing high extinction threat due to rapid loss of habitat. No attempt was made to record the behavior of this bird during forage and breeding. Thus an attempt was made to present an ethogram of the species describing 36 individual behavior, grouped under 14 distinct categories: resting, alert, comfort, maintenance, locomotion, foraging, antagonistic, sexual, chick care, foraging and vocalization. The observation period had been confined to 64 weeks (2012 to 2016) during day time both at forage and nesting sites. All the behavioral characters were sketched in addition to videogram and normal photograph and presented in the text. The data recorded are the base line data, could be used in captive breeding as part of conservation and they may elucidate upon the formulation of strategy for both in situ and ex situ conservation.
