The biggest factor in the success of breeding animals is selection of foods, which is determined by quality and quantity of
habitats(Newton, 2003), in the case of This high biomass wetlands as an indicator of ecosystem function about Common
Kestrel's choice of hunting area is expected to be an important clue of quality and quantity of habitats. For this study, it is
divided into four types(Glasslands, Paddy fields, Dry fields, Rparian land) about Common Kestrel's hunting area in
Yugu-eup, Gongju-si, Chungcheongnam-do, Recorded the behavior of Common Kestrel for three years during the
breeding season from March to June(2014~2016). Result of investigation, hunting area showed a high hunting behavior in
riversides and flight-hunting was frequently investigated from may to June. In addition flight-hunting's main food
acquisition is mammal(the vole), while perching behavior's main food acquisition is insect according to the fact
flight-hunting were mainly done in riversides, perching behavior were highly investigated than flight-hunting at glasslands
and paddy fields and dry field. Hunting spot's coverage rate of plants covering the ground showed differences depending on
hunting areas, but height of plants were not significant. Height of the plant according to hunting methods of flight-hunting
to catch mammal(vole) was analyzed to prefer lower height than perching behavior Based on these results riversides are
considered as a very important environmental factors for Common Kestrel's prey selection in breeding session.
