棕熊搶食影響灰狼行為

在美國黃石公園,有些棕熊會搶掠灰狼群獵殺的食物,改變了牠們的行為習慣。當灰狼辛苦狩獵後,棕熊便上前食用,通常灰狼都會屈服退出,或等待棕熊離開。當棕熊出現時,灰狼的獵殺頻率會降低。研究發現,牠們可能會花更多時間處理及捍衛獵物,並來回移動避開棕熊。

In Yellowstone National Park, some brown bears are sealing wolvess kills, changing their behaviours. A research found bears would take over a kill after the wolves success; wolves usually will give-in and wait aside or move on. wolves hunt less when bears were present. Study found that the wolves spending more time defending and handling their kills by moving around more frequent to avoid bears.
