抄録

To prevent Brown-Eared Bulbuls Hypsipetes amaurotis damaging kiwifruit buds, their distress call (DC) was played in a kiwifruit orchard during early spring in 1992, 1993 and 1995. The number of bulbuls in the orchard decreased during DC playback. At trees near the speakers, damage in 1992 and 1993 was reduced to levels acceptable to growers. However, in 1995, when damage was generally greater throughout the orchard, severe damage occured even close to the speakers. Damage was always severe at sites close to roosts or perches. In 1995, we also observed Japanese Waxwings Bombycilla japonica damaging the buds. This is the first report of damage to kiwifruit buds by Brown-Eared Bulbuls and Japanese Waxwings.
