Beluga whales, the “canaries of the sea”, have alot to say. Through their wide repertoire of vocalizations they are always chatting, chirping and singing. Their highly sophisticated vocal repertoires and acoustic systems, including echolocation, suggest that they can form very complex relationships and groups. They are very sophisticated when it comes to their communication channels among one another, and in the summer seasons can be found gathering in the hundreds creating a cacophony of sound.

Listen to the sounds of beluga whales! Did you know that a hydrophone is an underwater device that detects and records ocean sounds from all directions? This video shows a hydrophone in use to play the sounds of beluga whales beneath the boat in the Churchill River. Beluga whales are very vocal whales and listening to this video it is easy to hear why they get the nickname canaries of the sea. | Frontiers North Adventures
