For developing a policy to control a crow population, we determined a planning area based on the characteristics of the Minimum convex polygon (MCP) method. The calculated MCP home-range size indicates that control policy measures should be conducted in conjunction with neighboring municipalities. We also used the fixed kernel method to estimate crow's core area, and then determined the land-use characteristics of this area. Crows used Lefy residential area, forest, fruits farm in Summer, they used fruits farm, urban area, forest in Autumn, and they used urban area, fuits farm, forest, grass farm in winter.
