notscientific writes "Each wolf has a unique howl, which scientists can now decipher through voice recognition (audio), allowing them to identify wolves individually. The scientists developed sound analysis code that can tell which wolf is howling with 100% accuracy. Previously, pitch was used to tell wolves apart, but these only achieved a relatively low accuracy rate. This sound analysis is important because it could well give researchers the first proper way to effectively monitor wolves in the wild. Interestingly, this research comes after the recent finding that dolphins have names for one another. In the case of wolves, their howls are essentially their names."
