WEST SACRAMENTO, Calif. — Biologists tried unsuccessfully Thursday to use recorded siren songs of humpback whales to lure an injured female and her wounded calf from a shipping channel and back toward the Pacific Ocean 90 miles away.

When the researchers played the underwater recordings from an 87-foot Coast Guard cutter, the whales swam away from the sound rather than toward it.

Hours later, the whales were still swimming at the Port of Sacramento, where they have been since Tuesday. Scientists then decided to move the sound equipment to a 25-foot Coast Guard vessel, believing the noise from the larger ship's generator may have interfered with the whale sounds.
