5th Dead Whale Found In Less Than Month Near San Francisco Bay
不到一个月，旧金山湾附近发现了第5头死鲸
SAN FRANCISCO (AP) — A fifth dead whale has been discovered in less than a month around San Francisco Bay.
旧金山(美联社)——不到一个月的时间里，在旧金山湾附近发现了第五头死鲸。
The whale was discovered near Fort Funston on Friday, south of the San Francisco Zoo. A cause of death has yet to be determined.
这头鲸鱼是周五在旧金山动物园南部的Funston堡附近被发现的。死因尚未确定。
April is the beginning of the gray whale’s northern migration, so finding dead whales near the bay is not unusual, but experts were especially concerned when, a few weeks ago, four dead whales were found in the span of nine days.
4月是灰鲸向北迁徙的开始，因此在海湾附近发现死鲸并不罕见，但几周前，在九天内发现了四只死鲸时，专家们特别担心。
“It’s alarming to respond to four dead gray whales in just over a week because it really puts into perspective the current challenges faced by this species,” Dr. Pádraig Duignan, director of pathology at The Marine Mammal Center, said earlier this month.
海洋哺乳动物中心(Marine Mammal Center)的病理学主任Pádraig Duignan博士本月早些时候说:“一周多的时间里就有4头灰鲸死亡，这很令人担忧，因为这确实让我们看到了灰鲸目前面临的挑战。”
The carcass of a 41-foot (13-meter) adult female gray whale landed at San Francisco’s Crissy Field on March 31.
3月31日，一只41英尺(13米)长的成年雌性灰鲸的尸体在旧金山克里希菲尔德上岸。
A second adult female was found April 3 in Moss Beach in San Mateo County. A third was found April 7 floating near the Berkeley Marina and the following day another whale washed up in Marin County’s Muir Beach.
4月3日，在圣马特奥县的莫斯海滩发现了第二只成年雌性海豚。第四只鲸鱼于4月7日被发现漂浮在伯克利码头附近，第二天又有一只鲸鱼被冲上马林县的缪尔海滩。
A video of the fifth dead whale was posted on social media Friday.
周五，第五头死鲸的视频被发布在社交媒体上。
The whales migrate 10,000 miles (16,090 kilometers) to winter off Mexico’s waters, where they mate and birth calves near the coast of Baja California. They head back north and stay off the coast of California in spring and summer to feed on anchovies, sardines and krill before continuing on their northerly migration to Arctic waters.
这些鲸鱼迁徙1万英里(16090公里)到墨西哥水域过冬，在那里，它们在下加利福尼亚海岸附近交配并产下幼崽。它们会返回北方，在春季和夏季停留在远离加利福尼亚海岸的地方，以凤尾鱼、沙丁鱼和磷虾为食，然后继续向北迁移到北极水域。
In 2019, at least 13 dead whales washed ashore in the Bay Area and scientists said they feared it was because the animals were starving and couldn’t complete their annual migration from Mexico to Alaska. Biologists have observed gray whales in poor body condition during their annual migration since 2019, when an “unusual mortality event” was declared by the National Oceanic and Atmospheric Administration.
2019年，至少有13头死鲸鱼被冲上了海湾地区的海岸，科学家们表示，他们担心这是因为这些动物饥饿，无法完成从墨西哥到阿拉斯加的年度迁徙。自2019年美国国家海洋和大气管理局(National Oceanic and Atmospheric Administration)宣布发生“异常死亡事件”以来，生物学家一直观察到灰鲸在它们的年度迁徙中身体状况不佳。
Malnutrition, entanglement in fishing gear, and trauma from ship strikes have been the most common causes of death found by experts in recent years.
营养不良、被渔具缠住、船只撞击造成的创伤是近年来专家发现的最常见的死亡原因。
A necropsy of a whale found at Muir Beach revealed significant bruising and hemorrhaging to muscle around the whale’s jaw and neck vertebrae consistent with blunt force trauma due to ship strike.
对在缪尔海滩发现的一头鲸鱼的尸检显示，鲸鱼的颚部和颈椎周围的肌肉有明显的瘀伤和大出血，这与船只撞击造成的钝器伤一致。
