My research is focused on conservation behavior which integrates behavioral ecology and conservation biology. In my previous research, I studied on a threatened tropical magpie: Sri Lanka Magpie (Urocissa ornata) to understand the significance of behavioral traits in conservation of tropical avian species. Specifically, I am interested in studying of the cooperative breeding behavior, habitat/nest site selection and vocalization of tropical ‘blue green magpies’. In addition, I investigate social information sharing between avian heterospecifics by using vocalization and vocal mimicry in collaboration with Assoc.Prof. Eben Goodale and Prof. Sarath Kotagama.

In my current research, I investigate social information use between migratory Pied Flycatchers (Ficedula hypoleuca) and resident Great tits (Parus major) in collaboration with Dr. Robert Thomson and Dr. Toni Laaksonen. I focus on answering following questions.

a)      How local conspecific density influences social information gathering in Pied Flycatchers.

b)      Understanding the mechanisms of heterospecific social information gathering between Pied Flycatchers and Great tits.
