Humpback whales in the waters off the West coast of the island of Hawai'i near Puako
This is one of the main seasonal breeding grounds of humpback whales. From around the beginning of January, the whales sing elaborate songs in 4 part loops which are evolved collectively during the season. They return to the Arctic around the beginning of May.
The Jupiter Research Foundation has a long standing project to make the sounds available to researchersa and the public. They have designed and built dedicated remote controlled mobile platforms to support the hydrophones, from which the audio is sent to a base station via Ultra High Frequency networks and from there via a radio repeater to the internet.
In a seminar on humpback whale song at the Cornell Lab of Ornithology, Katy Payne demonstrates that when recordings of whales singing are speeded up X 10, they sound a lot like birds.
