Dialogues with community constituents are indispensable for scientists whose research fields and applications are closely related with communities throughout the research processes of consensus building on executions of research projects, making decisions on research policies, sharing the products of the projects, corrections. What kind of guidance is required for scientists to maintain a dialogue with the society? Using mailing list and web portfolio, we recorded a process of planning and executing a science cafe with two researchers who research for reintroduction of Crested Ibis (Toki) into Sado Island. Additionally, to understand the reality of the research, we observed the field research by the scientists in Sado Island. This record and analysis about difficulty and the solution of the science cafe serves scientists as a effectively guidance.
