Spotted
The Black-billed Koel is an endemic species of Indonesia, known for its entirely black bill distinguishing it from other koels. Males are glossy black with a unique dark bill, while females are barred and spotted.
Where to spot
Endemic to the island of Sulawesi and nearby smaller islands in Indonesia. Inhabits forests, forest edges, and often gardens or cultivated areas, adapting to human-modified landscapes.
How to spot
The key identifier for this species is its entirely black bill in both sexes, which sets it apart from other koel species. Listen for its characteristic loud, repetitive calls, similar to other koels but possibly with regional variations. Look high in trees, especially where potential host nests might be.
When to spot
Observable year-round within its range. Most vocal during the breeding season, which can vary depending on local conditions and the breeding cycles of its specific host birds.

This species is a classic example of brood parasitism, relying on other bird species, likely crows, to incubate its eggs and raise its young, showing a fascinating evolutionary strategy.
