Tangkoko Nature Reserve in North Sulawesi is celebrated as a birdwatcher’s paradise, home to an extraordinary array of endemic species—including the elusive and fascinating Yellow-billed Malkoha (Rhamphococcyx calyorhynchus). This unique bird, found only on Sulawesi, is a true highlight for those exploring the region’s rich biodiversity.
The Yellow-billed Malkoha is a cuckoo species endemic to Sulawesi, recognized for its striking yellow bill and distinctive plumage. Unlike many cuckoos, this bird is not a brood parasite but instead stays in the forest canopy, often foraging quietly among the branches. It is typically shy and prefers the dense cover of lowland rainforests, where it feeds on insects, small reptiles, and fruit.

Habitat and Behavior
This malkoha thrives in subtropical or tropical moist lowland forests, making Tangkoko’s lush, protected landscapes an ideal habitat. Observers may spot the Yellow-billed Malkoha as it moves stealthily through the foliage, sometimes following groups of macaques to catch insects disturbed by their activity. Its presence is often revealed by soft calls or the occasional flash of its colorful bill among the leaves.
