NAVAL sonar makes whales flee from prime feeding sites, leaving them hungry when they finally return. Peter Tyack of Woods Hole Oceanographic Institution, Massachusetts, and colleagues tracked the activity of Blainville’s beaked whale (Mesoplodon densirostris) during operations at a US navy centre near Andros Island, Bahamas. The area encompasses an underwater canyon that is a prime hunting ground for these deep divers. By satellite tagging one whale and listening out for the echolocation clicks of others using underwater microphones, the team found that whales stopped echolocating and moved away from the area during the tests (PLoS One, DOI:
