About Green-billed Coucal

The Sri Lanka Green-billed Coucal (Centropus chlororhynchos) is a unique and elusive bird species found only in Sri Lanka. This bird is known for its distinctive green beak, and it has rich brown and black plumage. The Sri Lanka Green-billed Coucal is one of the rarest and most enigmatic species in the country, with very little known about its behavior and ecology.

Appearance and Range of Green-billed Coucal

The Sri Lanka Green-billed Coucal is a large bird, measuring around 40 cm in length and weighing approximately 200 grams. The bird’s most distinctive feature is its bright green beak, which contrasts sharply with its dark plumage. The bird’s feathers are primarily brown and black, with a slight iridescence in certain lighting conditions.

The Sri Lanka Green-billed Coucal is endemic to Sri Lanka, meaning it is found nowhere else in the world. Its range is limited to the island’s lowland forests and wetlands, where it is most commonly found in dense thickets and undergrowth. Despite its limited range, the bird is thought to be relatively common in some areas, although it is rarely seen due to its secretive nature.

Behavior and Ecology of Green-billed Coucal

Very little is known about the behavior and ecology of the Sri Lanka Green-billed Coucal, as the bird is notoriously difficult to observe in the wild. The species is believed to be primarily arboreal and is thought to feed on a variety of insects and small invertebrates found in the dense undergrowth of Sri Lanka’s forests.

The bird is also believed to be monogamous, with pairs defending territories and constructing large, domed nests in thick vegetation. The nesting habits and breeding behavior of the Sri Lanka Green-billed Coucal remain largely a mystery, however, and more research is needed to fully understand the species’ reproductive biology.
