The Dolphin Communication Project studies a group of Atlantic spotted dolphins living near the island of Bimini in The Bahamas. Using a special video camera equipped with underwater microphones (i.e., hydrophones), we are able to record their behavior as well as the myriad of sounds they produce. Our equipment makes it possible for us to determine which dolphin is producing which vocalization. This is how we know for sure that the below audio file is a whistle produced by Freckles! As a proud adoptive parent of Freckles, you can now download a recording of her whistle to your computer, mp3 player or cellular phone. Freckles and the other Bimini dolphins use whistles primarily to communicate with each other under water – a very useful way to stay in touch at night when the ocean is dark, or when diving into deeper waters.
