Description
The orange-bellied leafbird is a small passerine, measuring approximately 14–16 cm in length. Adults display a predominantly bright green plumage on the back, wings, and tail, with a contrasting vivid orange coloration on the belly and vent area. The throat and breast are typically a paler green, and the undertail coverts may show a slight yellowish hue. The bill is slender, slightly curved, and blackish. Males and females are similar in plumage, with females occasionally exhibiting a slightly duller orange on the ventral side. The species’ vocalizations consist of high-pitched, melodious whistles and rapid series of notes, often delivered from concealed perches within foliage.
Distribution and Habitat
Chloropsis hardwickii is native to the Indian subcontinent, with a range extending across the lower Himalayas, the Western and Eastern Ghats, and into parts of southern India and Sri Lanka. It inhabits subtropical and tropical moist evergreen and semi‑evergreen forests, as well as secondary growth, plantations, and shaded gardens. The bird is typically found from low elevations up to about 1,800 m, preferentially occupying the mid‑canopy and forest edge strata.
Behavior and Ecology
- Diet: The species is omnivorous, feeding on a mixture of insects (including caterpillars, beetles, and hemipterans), other arthropods, and a variety of fruits and nectar. It frequently forages by gleaning insects from leaves and by sallying for aerial prey.
- Territoriality: Pairs or small family groups maintain territories that are defended through vocal displays and occasional aerial chases.
- Social Structure: Outside the breeding season, the orange-bellied leafbird may join mixed‑species foraging flocks, especially in the canopy.
Breeding
Breeding occurs primarily during the pre‑monsoon months (March to May) in most of its range, though timing can vary regionally. The nest is a compact cup constructed from moss, lichens, and fine plant fibers, typically placed on a forked branch or within a dense shrub. Clutch size is usually two to three eggs, which are dull white with brown speckles. Both parents participate in incubation (approximately 12–14 days) and in feeding the altricial chicks until fledging, which occurs about 12 days after hatching.
Conservation Status
The International Union for Conservation of Nature (IUCN) classifies the orange-bellied leafbird as Least Concern. The species is considered relatively common within suitable habitats, and it tolerates a degree of habitat modification. However, ongoing deforestation and conversion of forested land to agriculture pose localized threats, particularly in fragmented landscapes.
