Young Gray Whale Dies After Swimming Up River in Washington State

A juvenile gray whale was discovered deceased after traveling 20 miles inland into a Washington state river, according to a local marine mammal research group. The Cascadia Research Collective confirmed the death of the whale, which had been seen in the Willapa River over recent days, and suggested starvation might be a contributing factor.

The group is currently assessing the location’s safety to conduct an examination. The whale, affectionately named “Willapa Willy” by locals, was first observed last Wednesday in the north fork of the river, approximately 145 miles southwest of Seattle. At the time, it was described as thin but showing no signs of distress or injury.

Migration Patterns and Food Scarcity

Gray whales typically migrate northward along the Pacific Coast during spring to feed in the Arctic. John Calambokidis, a research biologist with the Cascadia Research Collective, told the Associated Press that such journeys often deplete their energy reserves. “This whale likely faced a more intense search for food,” he noted, implying the animal may have been driven inland due to dwindling resources.

Calambokidis emphasized that the eastern Pacific gray whale population has encountered reduced prey availability in the northern Bering and Chukchi seas off Alaska. “The core issue appears to be their struggle to find sufficient food in the Arctic,” he added, highlighting the species’ ongoing challenges.

Additional Incidents and Population Concerns

Earlier this month, two adult gray whales were found dead in the Ocean Shores area near the Willapa River. Cascadia Research Collective stated that both were malnourished, with the male also suffering head trauma consistent with a ship collision.

According to NOAA Fisheries, the latest winter survey indicates a continued decline in gray whale numbers. The agency estimates the population at around 13,000, the lowest level recorded since the 1970s. These whales, which can reach lengths of 15 meters and weigh up to 40,000 kg, are also vulnerable to vessel strikes and entanglement in fishing equipment during their extensive migrations. The organization notes that long-term bonds between individuals are uncommon, as they usually travel alone.

“When gray whales deplete their energy reserves, they often seek new feeding grounds with greater urgency,” Calambokidis remarked.
