鲸群之声 Voices of the pod

奇尔卡特山脉附近的虎鲸，林恩运河，阿拉斯加州

在阿拉斯加东南部白雪覆盖的奇尔卡特山脉映衬下，一头虎鲸浮出林恩运河水面。虎鲸是海豚科体型最大的成员，也是海洋中最具辨识度的捕食者之一。阿拉斯加内湾航道寒冷且营养丰富的水域提供了充足的觅食地，既维系鲑鱼洄游，也滋养种类繁多的海洋生物，为这些非凡动物提供支持。

科学家确认了数个不同的虎鲸种群，各自拥有独特的食谱、狩猎策略和社会传统。有些专门捕鱼，有些则捕食海豹、海狮及其他海洋哺乳动物。虎鲸生活在由经验丰富的年长雌鲸带领、关系紧密的家族群体中，并通过每个鲸群特有的叫声交流——这种声音传统代代相传。林恩运河及其周边水道为这些高度聪明的海洋哺乳动物提供了重要栖息地，也是野外观察它们的壮丽场所。

An orca near the Chilkat Mountains, Lynn Canal, Alaska

An orca breaks the surface of Lynn Canal against the backdrop of the snow-capped Chilkat Mountains in Southeast Alaska. Also known as the killer whale, the orca is the largest member of the dolphin family and one of the ocean's most recognizable predators. The cold, nutrient-rich waters of Alaska's Inside Passage provide abundant feeding grounds, sustaining salmon runs and a rich variety of marine life that supports these remarkable animals.

Scientists recognize several distinct orca populations, each with its own diet, hunting strategies, and social traditions. Some specialize in catching fish, while others prey on seals, sea lions, and other marine mammals. Living in tightly bonded family groups led by experienced older females, orcas communicate through distinctive calls unique to each pod—vocal traditions passed down through generations. Lynn Canal and its surrounding waterways offer a vital habitat for these highly intelligent marine mammals and a dramatic setting for observing them in the wild.
