Resident species

Comportamento

The Moheli scops owl is strictly nocturnal and becomes active only after sunset. Calling males have been recorded in September. The diet is probably mainly made up of insects.

Conservazione

The species was only described in 1998. It has an estimated population of 400, and is classified as critically endangered due to it being restricted to such a small area, which is being rapidly deforested. In 1995, only five percent of the island still had intact, dense, humid forest. As well as habitat loss, other threats to the Moheli scops owl include hunting and black rats, which may eat its eggs and young but also compete with it for food. At present, the montane forest where the Moheli scops owl occurs is not protected.
