Indri indri | Indri


Good spot: Andasibe-Mantadia National Park, Toamasina Province, Madagascar



Taxonomy & Occurrence

Indri indri is a monotypic species. Its geographic range extends along the eastern lowland and montane forest belt of Madagascar, as far south as the Anosibe an’ala Classified Forest and as far north as the Anjanaharibe-Sud Special Reserve [1].


IUCN Conservation Status

Critically Endangered


The Indri is recognised by its trademark wailing calls which echo across its range. The largest lemur and a tremendous leaper, the Indri is one of the flagship primate species and a highlight of any visit to Madagascar.

Seeing this Species


The Indri varies in colour; from predominantly black, especially towards the northern extent of its range, to a pied black-and-white variant towards its southernmost range. Aside from its tell-tale vocalisations and size, the Indri is otherwise identified by its vertical clinging position, its stunted tail, and prominent, tufted ears.


Andasibe-Mantadia National Park, Toamasina Province, Madagascar 

This is one of the most popular national parks in Madagascar, and is accessible from the small village of Andasibe on the tarred road of RN2, about 3 hours’ drive from the capital, Antananarivo. There are numerous hotels neighbouring the national park and a well-run park office, from where compulsory guides can be arranged. The national park is divided into two parcels: the smaller and more accessible Analamazaotra Special Reserve, and the much more expansive Mantadia National Park to the north.


There are various trails with numerous offshoots throughout both sections of the Andasibe-Mantadia National Park. The best time for seeing the Indri is early morning, between 7 am and 11 am, when the morning calls are at their most frequent [2]. Follow your ears! And look out for 11 other species of lemurs in this national park!
