Scientists have tracked a critically endangered western gray whale from its native habitat in the chilly Pacific Ocean off Russia for thousands of miles to balmy lagoons off the coast of Mexico — a first for the rare whales.
Now, the 9-year-old female — dubbed Varvara, the Russian equivalent of Barbara — is making her way back up the west coast of North America, and appears to be returninghome.
On Friday (March 16), Varvara was near the Canadian border, and traveling about 100 miles (160 kilometers) a day.
