澳洲菲利普島上渡鴉會成對攻擊正在繁殖的小藍企鵝！其中一隻烏鴉會分散成年企鵝的注意力，另一隻負責挖企鵝的巢穴取蛋或雛鳥。研究人員還觀察到有些渡鴉會將成年企鵝扔下懸崖，或騷擾牠們好幾個小時直到企鵝放棄巢穴。這種新的威脅大約20年前才開始出現，而且只發生在菲利普島的渡鴉身上，而這個島是小藍企鵝最大的繁殖地。
Ravens are working in pairs to attack breeding little blue penguins! one of the ravens will distract the penguin parent while the other one dig holes into the penguins’ burrow to grab their eggs or chicks. Researchers also observed ravens throwing the parent penguins off a cliff or harassing them for hours until the penguins gave up and abandon their nests. This new threat only started about 20 years ago, and only happens to the ravens in the Phillip Island , which is the largest breeding site for little blue penguins.
