Humpback whales lost near Vacaville, California!

A humpback whale mother and her calf made the 90-mile river journey from the San Francisco bay to the Port of Sacramento in the Sacramento River.

Biologists hope to get the whales back into the ocean, where food is more plentiful and the saltwater can heal their cuts. Recorded whale sounds worked in 1985 with a humpback nicknamed Humphrey, which swam in the delta for nearly a month before returning to the Pacific.

The two likely had been on their northward migration from Mexico up the California coast when they were sidetracked, biologists said. Because they are at the end of their hibernation season, they have less blubber to rely on for fuel than they would later in the summer or fall.
