Abstract

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.

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.
