Haunting

YKWIA shared a video with me tonight of Indri lemur calls from Madagascar, which sound somewhat like whales. This isn't the video he showed me, but it will give you the idea:



The lemur, also called a Babakoto ('baba-koot') is endangered due to loss of habitat and hunting, the latter despite cultural taboos and legends of a common ancestry. According to the Wikipedia article on the Indri:

Most legends establish a closer relationship between the Indri and humans. In some regions it is believed that there were two brothers who lived together in the forest until one of them decided to leave and cultivate the land. That brother became the first human, and the brother who stayed in the forest became the first Indri. The Indri cries in mourning for his brother who went astray.
