초록

조류 종별로 과수원의 과실을 가해하는 행동 특성을 확인하고자 본 연구를 수행하였다. 각 조류별로 특징적인 경향을 확인할 수 있었는데, 까치는 부리로 과피를 수직으로 쪼며 물까치와 직박구리는 큐티클층에 부리가 미끄러진 흔적과 과실 내부에 주머니 모양으로 원형 흔적을 남겼다. 봉지재배를 하는 배와 사과 과실은 조류의 종류에 따라 다른 섭식행동을 유발시킬 수 있다. 까치의 경우 봉지의 존재 여부를 떠나 과실을 가해 할 수 있으나 물까치와 직박구리는 건전한 봉지로 씌워져 있을 경우 가해하지 않았다. 그리고 사육상 시험에서 물까치와 직박구리는 온주밀감과 사과 과실보다는 배 과실을 더 선호하였다. 물까치와 직박구리의 피해를 경감시키기 위해서 봉지재배를 하는 과실의 경우 봉지가 훼손되지 않도록 할 필요가 있다. 또한 제주지역에 물까치가 유입되지 않도록 해서 감귤 과실피해를 막아야 한다.

To investigate the bird's dieting behavior for several fruits in orchards, this study was carried out in 2008. Black-billed magpies (Pica pica), azure-winged magpies (Cyanopica cyanus), and brown-eared bulbuls (Hypsipetes amaurotis) made their unique marks on the surface of pear and apple fruits; black-billed magpies pecked fruits strongly and left round holes with perpendicular angle, whereas those of azure-winged magpies and brown-eared bulbuls were sack-shaped with narrow neck and marked unique stripes on the skin. For the fruits of pear and apple from bagging practices, the birds showed different foraging behavior; black-billed magpies could injure all kinds of fruits whether with paper bags or not, but azure-winged magpies and brown-eared bulbuls could not attack the fruits with paper bag. Azure-winged magpies and brown-eared bulbuls preferred pear fruits to those of apples and satsuma mandarins in the cage trials. To reduce the injuries by azure-winged magpies and brown-eared bulbuls on pear and apple fruit, wrapping bag should not be impaired. Introducing azure-winged magpies to Cheju should be prohibited for the potential citrus injury by them.
