This is a species of cuckoo in the Cuculidae family and another Sulawesi, Indonesia endemic. Sometimes seen feeding near troops of Sulawesi Macaque monkeys. Breeding habits have been little studied and its nest has never been described. Occurs in primary and secondary rainforest. One reason for its doing well is its ability to survive in secondary forest. Garden birds are not common in Sulawesi as many of the birds are more secretive and adaptive to primary forest. Destruction of this primary forest is a large concern for the many primary forest endemics. Local people in Sulawesi also know of associations between macaques and certain birds, particularly hair-crested drongo (Dicrurus hottentotus) and yellow-billed malkoha (Phaenicophaeus calyrhynchus). The farmers call these birds ‘burung monyet’ (monkey birds) and use the conspicuous calls of drongos and malkohas as signs of macaques' approaches to their fields journals.cambridge.org/action/displayAbstract;jsessionid=...
