A young gray whale has been found dead after swimming 20 miles (32.2 km) inland up a river in Washington state, as reported by a local scientific research group, which suggested that hunger might be a contributing factor.

We are saddened to confirm that the whale seen in the Willapa River over the past few days is deceased, announced the Econscient Research Collective in a social media update on Saturday.

The group is currently assessing the safety of the location for a potential examination of the whale.

The juvenile whale, affectionately nicknamed 'Willapa Willy' by locals, was first spotted last Wednesday in the north fork of the river, approximately 145 miles southwest of Seattle.

At the time of its sighting, the whale appeared thin but was behaving normally, with no visible signs of injury. Research teams hoped it would find its way out of the river but sadly, it did not.

Gray whales typically migrate long distances along the Pacific Coast for feeding in the Arctic, utilizing their nutritional reserves along the journey. John Calambokidis, a research biologist with the Cascadia Research Collective, explained that diminished food availability in the northern Bering and Chukchi seas off the Alaskan coast could prompt gray whales to seek alternative feeding areas.

Calambokidis stated, Gray whales are facing a major crisis, and a significant part of it is related to their feeding on prey in the Arctic.

This tragedy is not an isolated incident; earlier this month, two adult gray whales washed ashore dead in the nearby Ocean Shores area, both malnourished, with one showing signs of trauma consistent with ship strikes. The National Oceanic and Atmospheric Administration (NOAA) Fisheries has reported a continuing decline in gray whale populations, estimating only about 13,000 remaining— the lowest count since the 1970s.

This situation starkly highlights the threats faced by gray whales during their long migrations, including vessel strikes and entanglement in fishing gear, emphasizing the urgent need for conservation efforts.
