The singing of humpbacks at Silver Bank has been documented and studied by behavioral scientists. During mating season, male humpbacks sing to either attract females or defend their territory from other male whales, much like birds do with their own songs. The whale's song is haunting and complex. It sounds like an eerie series of chirps, squeaks, whistles and grunts. It is unlike anything you have ever heard.
Scuba divers can hear the singing if they hold their breath and pay attention.
Snorklers can also hear the songs, but they have to dive at least 10 feet deep to get below the noisy surface layer of water. The song lasts about 10-20 minutes, it has a beginning, middle and end, and all males of the same stock sing the same song. Thus, biologists can identify where a whale comes from by listening to its song. That's all for now. It is believed that these humpback whales migrate well offshore in deep ocean waters.
