Decoder Ring A team of scientists has a new idea for how to save migrating blue whales from dangerous collisions with ships: shut up and listen. It turns out that there’s a distinct change in the blue whale’s song just before it begins its annual migration south, Popular Science reports . By paying attention to those changes, the Stanford University scientists say, they might be able to warn ship operators in the area of the upcoming migration. Fair Warning Blue whales summer in the northeast region of the Pacific Ocean but travel to the coast of Central America in Autumn, PopSci reports, where they breed and wait out the cold weather. According to the team’s research , published Thursday in the journal Current Biology , the whales sing during the night, but switch to a daytime song right before their migration begins. “There is a near real-time signal of what these animals are doing out in a habitat that’s historically been really difficult to observe,” Stanford biologist and study coauthor William Oestreich told PopSci . Whale Strike Getting advance warning would be great both for whales and the boats in the areas, as collisions can be destructive for vessels […]
