Gray whales learn daring feeding strategy in Puget Sound: Digging for ghost shrimp at high tide

Print article
SEATTLE Every spring, a small group of about a dozen gray whales pauses along an epic migration from calving lagoons in Baja California to their feeding grounds in the Arctic. They travel more than 170 miles off their coastal migration route, to stop off in northern Puget Sound. There, they linger from about March through May.
Now scientists think they know why the Sounders, as this beloved group of regulars is known, likes to visit and hang around.
New research confirms these whales have figured out a brilliant feeding strategy.
Combining drone photography with long-term data on the Sounders has enabled scientists to track the body condition of these whales from when they first enter Puget Sound, until their departure to rejoin the migration north along the coast. ....

As global temperatures rise and warm the coldest parts of the world, scientists are watching for changes to species that live there. A new study has found evidence connecting the rapid warming of the region with a physical decline in three species of Alaska seals.
For 12 years, researcher Peter Boveng with the National Oceanic and Atmospheric Administration led a team that monitored ribbon and spotted seals in the Bering Sea. They were specifically monitoring body condition, or how fat the seals were. Boveng says what they found was the youngest seals were getting smaller. ....
