Répartition et habitat

This myna is endemic to the humid forests of hilly districts of the Indonesian island of Sulawesi. Its main habitat here is forest fringes, clearings, scattered areas of woodland and secondary forests, although it is sometimes found in primary forests. It is also present on the smaller islands of Lembeh, Muna and Buton; these are lowland islands and the habitat is mostly grassland savannah with patches of evergreen woodland in which the bird is primarily found.

Migration

Resident species

Comportement

The species usually feeds high in the forest canopy. It usually occurs in pairs or small family groups, but sometimes solitary individuals can be seen. Immature individuals may join flocks of fiery-browed starling (Enodes erythrophris) and it often associates with groups of other fruit-eating birds.<p>Little is known about the breeding habits of this bird. Its diet is estimated to consist of about 44% fruit and 52% invertebrates, the balance being taken up by small vertebrates. It is a non-migratory species but presumably moves about the forest in response to the ripening of fruits on different species of tree.
