The species is an opportunistic feeder, which is why it is most commonly found in habitats with a range of prey.

Movements and Migration

The Moluccan Drongo-Cuckoo is a non-migratory bird. This means that it stays in its range year-round.

However, the bird is known to make irregular movements depending on food availability.

During the breeding season, the Moluccan Drongo-Cuckoo becomes more vocal.

The male birds will perform a courtship display where they will flutter their wings and make a variety of vocalizations to attract a mate. Once the pair bond is formed, the birds will construct their nest, which usually takes the form of a shallow cup built in small shrubs or trees.

The Moluccan Drongo-Cuckoo is known to parasitize the nests of other bird species to ensure their young’s survival. This behavior is common in cuckoo species, and Moluccan Drongo-Cuckoo is no exception.

The birds usually lay one egg per host nest and will abandon their egg-laying duties once the eggs have been deposited. The foster parents do all the work of incubating and rearing the chick.

The Moluccan Drongo-Cuckoo chick hatches first, and it will often throw the host’s eggs and chicks outside the nest to ensure that the host parents only focus on taking care of their young chick. The Moluccan Drongo-Cuckoo chicks grow rapidly and are often ready to fledge the nest within two weeks after hatching.

After leaving the nest, the young bird will call out for the host parents, who will continue to feed and care for it until it becomes self-sufficient.

Conclusion

In conclusion, the Moluccan Drongo-Cuckoo occupies a variety of habitats and is an opportunistic feeder. The bird is non-migratory and makes irregular movements depending on food availability.

During the breeding season, male Moluccan Drongo-Cuckoo will display courtship behavior to attract a mate, and the species has a unique nesting behavior where it parasitizes the nests of other bird species to ensure its young’s survival. Overall, the Moluccan Drongo-Cuckoo is an interesting bird species with unique behavior that is worth studying and protecting.

Diet and Foraging

Feeding

The Moluccan Drongo-Cuckoo is an insectivore and consumes a variety of insects, including caterpillars, beetles, termites, and ants. It forages for food by perching on a tree and scanning its surroundings for any prey movements.

Once it has located its prey, it will fly out to snatch it from midair, or it may search for prey on the ground.

Diet

The Moluccan Drongo-Cuckoo’s diet is adapted to the seasonal changes in the availability of prey. During the breeding season, when the availability of insects is highest, the bird feeds mostly on caterpillars.

This high protein diet is essential for the bird’s growth, development, and reproduction. During the non-breeding season, when the availability of insects is lower, the bird shifts to a diet of termites and ants.

Metabolism and Temperature Regulation

The Moluccan Drongo-Cuckoo is a small bird with a high metabolism, which means that it needs a lot of energy to maintain its body temperature. However, the bird has adapted to regulate its body temperature through behavioral changes, such as perching under the shade during the hottest parts of the day to avoid overheating.

Sounds and Vocal Behavior

Vocalization

The Moluccan Drongo-Cuckoo is mostly heard before being seen. It produces a variety of vocalizations, including a loud and metallic “ting-ting-ting” that lasts for 1 to 1.5 seconds.

The sound is often described as similar to the sound that a metal pipe makes when it hits a hard surface. The bird’s calls are used for communication with other birds of the same species, and it is more vocally active during the breeding season than at any other time of the year.

The Moluccan Drongo-Cuckoo’s crest-raising behavior is a part of its vocal display that is used for signaling purposes. The bird raises its crest by moving its head forward and then backward while making vocalizations.

This display is used to establish dominance during confrontations with other birds and to signal to its mate during courtship.

Conclusion
