The howl is one of the most fearful sounds to hear in the dead of night. While any human can identify the long mournful wailing sound as belonging to that of a predatory creature in general, it is very difficult to tell a werewolf howl specifically apart from a wolf howling…they both sound incredibly similar to the human ear. A good way to try to learn is to record howls, werewolf howl and wolf, slow them down, and listen to the pitch, tone, and length. The best time to listen for howling is during early morning or near dusk time.
Werewolf legend sometimes can be tracked by the werewolf howl.
