A juvenile gray whale that amazed Washington state residents after it swam 20 miles up a small river was found dead, and an official with a marine mammal research group suspects hunger may have driven the whale to new hunting grounds as the species’ population declines. The whale was discovered Saturday near Raymond, Washington, in the Willapa River, which feeds into the ocean at Willapa Bay. A number of gray whales are currently in the bay on their 5,000-mile spring migration from birthing grounds in Baja California, Mexico, north to feeding grounds in Alaska.
