摘要

我们描述了 2019 年澳大利亚夏季一群 A 型虎鲸捕食南极小须鲸（Balaenoptera bonaerensis）这一罕见事件。在南极半岛北部的布兰斯菲尔德海峡（Bransfield Strait），人们观察到一个由 11-13 头小须鲸组成的鲸群，并用照片和视频记录了它们捕杀和喂食小须鲸的过程。对这个鲸群的观察持续了大约一个小时，当时发现一些虎鲸个体正在进行狩猎行为。这种行为持续了大约 10 分钟，最后小须鲸被杀死。观察到三种不同种类的海鸟在小须鲸尸体上觅食。我们提供了这次邂逅的视频。

Killer whale predation on an Antarctic minke whale in the northern Antarctic Peninsula.

We describe the seldom observed event of a group of type A killer whale (Orcinus orca) predating on an Antarctic minke whale (Balaenoptera bonaerensis) in austral summer 2019. A pod of 11-13 individuals was observed - and documented by photographs and video - as they killed and fed on the minke whale in the Bransfield Strait, northern Antarctic Peninsula. The pod was being observed for about one hour, when some killer whale's individuals were noticed to be performing hunting behaviour. This lasted about 10 minutes, at the end of which the minke whale was killed. Three different species of seabirds were observed feeding on the minke carcass. A video of the encounter is provided.
