| Plaintive Cuckoo | Cacomantis merulinus | https://www.inaturalist.org/observations/256469576 |
The Plaintive Cuckoo (Cacomantis merulinus) is one of the birds from the Cuculidae family, often heard but rarely seen. Its unique, melancholic calls resemble a lament, which is why it is aptly named "plaintive."
Habitat and Distribution
The Plaintive Cuckoo has a wide distribution across South and Southeast Asia, including Indonesia. It can commonly be found in habitats such as scrublands, gardens, rice fields, secondary forests, and mangrove areas. Its remarkable adaptability allows it to thrive without reliance on primary forests.
Physical Characteristics
Adult Plaintive Cuckoos exhibit predominantly gray plumage on their head and chest, while their underparts are white with slight barring patterns. Their back feathers are brown. This species is relatively small to medium-sized, measuring approximately 22–23 cm in length.
Behavior and Habits
As a brood parasite, the Plaintive Cuckoo is well-known for laying its eggs in the nests of other birds, such as Prinias or Cisticolas. The young Plaintive Cuckoo competes with the host’s chicks for food and often pushes the host’s eggs or chicks out of the nest to ensure its survival.
This bird frequently produces distinctive calls that sound like “pi-pi-pi-pu-pu-pu,” which serve as an auditory marker of its presence in the wild.
Ecological Significance
As part of the ecosystem, the Plaintive Cuckoo plays a vital role in controlling insect populations, particularly caterpillars, which are its primary diet. Its presence contributes to maintaining the balance within the food chain.
Observation Notes
To observe the Plaintive Cuckoo, the best times are early morning or late afternoon when it is most vocal. Using binoculars can aid in spotting this elusive bird, as it often hides among shrubs or trees.
Why Is It Fascinating to Study?
The Plaintive Cuckoo serves as an intriguing example of brood parasitism in birds. Moreover, its distinctive calls make it easy to identify, even for novice birdwatchers.
