indri feeds in a tree in the moist montane forest of Andasibe-Mantadia National
Park. Indris are pair-bonded lemurs with perhaps the loudest high-pitched
call of any terrestrial animal. Their calls are duets, with either the male
or female leading off and the other chiming in (see Joyce A.
Powzyk, Natural History April 2002, page 82). Once you have heard these
musical calls, which carry for miles in the forest, you will never forget
them. Click on the sound file below to hear a recording we made on the trail,
with a few human voices in the background.
