Sometimes, a fierce eagle may come swooping down for a baby bird. When this happens, the whole isle will burst out cracking and cawing in angry protest and thousands of birds will take wing together, ready to defend their young and drive out the predator.

• 有时，凶猛的老鹰会突然飞来，企图扑食雏鸟，遇到这种情况，整个鸟岛就会发出愤怒的呼叫，数千只成鸟腾空而起，奋力将强敌逐出。
