초록

동물의 번식 성공에 가장 큰 요인은 먹이의 선택이고 먹이의 선택은 서식지의 질과 양에 의해 결정되어 지며, 생물량이 높은 습지의 경우 생태계 기능의 지표로서 황조롱이의 사냥 장소의 선택은 서식 장소의 질과 양을 알아보는 중요한 단서가 될 것으로 예상된다. 본 연구는 충남 공주시 유구읍의 황조롱이 사냥장소에 대해 4가지 유형(초지, 논, 밭, 하천변)으로 구분하여, 번식시기인 3월에서 6월까지 3년간 (2014년~2016년) 황조롱이의 행동을 기록하였다. 조사결과, 사냥의 장소는 하천변에서 높은 사냥행동을 보였고, 비행사냥은 5월과 6월에 많이 하는 것으로 조사되었다. 또한 비행사냥의 주요 획득 먹이는 포유류(쥐), 착지행동의 주요 획득 먹이는 곤충류로 조사되었다. 이에 따라, 하천변에서는 주로 비행사냥이 이루어졌으며, 초지나 논과 밭에서는 착지 행동이 비행행동에 비해 높게 조사되었다. 사냥이 이루어지는 지점의 식물이 땅을 덮는 피도는 사냥지역별 차이를 보였으나 식물의 높이는 차이를 보이지 않는 것으로 확인되었고, 사냥 방법에 따른 식물의 높이는 포유류(쥐)를 잡기 위한 비행사냥이 착지사냥보다 낮은 높이를 선호하는 것으로 분석되었다. 이러한 결과들을 바탕으로 황조롱이의 번식기 먹이 선택에서 하천변은 매우 중요한 환경 요소로 판단된다.

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.
