Mystery Night Sound – Ulu Muda, Malaysia

by | Apr 27, 2018 | Malaysia

Recorded around midnight on remote microphones left in primary rainforest along the banks of the Sungai Muda river. The sound appears to come from at least two individuals close to the microphones (one to the left and another in front or above) and at least two more in the far distance. I think it could be a Banded Langur (Presbytis femoralis) although I’m yet to find this call documented for this species. Dusky Langur (Trachypithecus obscurus) can also be heard in the background making alarm calls, and Pig-tailed Macaque were also present. Not sure what else it could be – a list of some mammals recorded in the reserve is available here – https://www.earthlodgemalaysia.com/mammals-of-ulu-muda
