Oriental Pied Hornbill

Identification

The Oriental Pied Hornbill is a medium-sized hornbill measuring 55–60 cm from head to tail, with a wingspan of 23–36 cm. It is considered one of the smallest and most common of Asian hornbills. The plumage is striking: the head, neck, back, wings and upper breast are black with a subtle green sheen, while the lower breast, abdomen, thighs and underwings are white. The tail is black with white tips on all feathers except the central ones. Males are noticeably larger than females, with a yellow bill (black at the base) and bright red eyes, while females are slightly smaller with a yellow bill and casque marked by black and brown patches, and grayish-brown eyes. Both sexes possess a laterally flattened casque that may form a protruding horn. Juveniles resemble adults but have an underdeveloped casque and lack the green gloss of adult plumage. Their calls are distinctive: crowlike sounds, braying notes, and harsh crackles and screeches.

Range & Habitat

This species has the largest distribution of any hornbill in its genus, occurring across the Indian subcontinent and throughout Southeast Asia, including eastern and northern India, Nepal, Bangladesh, Bhutan, Tibet, Myanmar, Thailand, Laos, Cambodia, Vietnam, Peninsular Malaysia, Singapore, Indonesia, Brunei and the Sunda shelf islands. It inhabits subtropical and tropical moist lowland forests, including dry and semi-evergreen forests, dry and moist deciduous forests, subtropical broadleaf forests, secondary forests, plantations and woodlands—making it adaptable to a range of forested environments.

Behaviour & Diet

Oriental Pied Hornbills are predominantly frugivorous, feeding on wild figs, melanoxylon berries, rambutans, palm fruit, papaya and fruits of liana plants. They supplement their diet with large insects such as grasshoppers, small birds including finches, small reptiles like lizards and snakes, amphibians, fish, bats, and occasionally eggs and hatchlings from other birds' nests. During the non-breeding season they feed more heavily on non-fig fruits and forage in flocks, selecting preferred trees from families including Annonaceae, Meliaceae and Myristicaceae. In breeding season, they shift toward lipid-rich fruits and invertebrates. As large seed dispersers, these hornbills play a crucial ecological role, translocating seeds to new microsites and shaping forest communities through their feeding behaviour.

Best Time & Places to See It

Oriental Pied Hornbills breed from January to June, typically commencing in February when rains arrive and fruit abundance peaks—making this an excellent time to observe breeding activity and pair behaviour. They occur across a vast range of lowland forest habitats throughout Southeast Asia and the Indian subcontinent. During the non-breeding season, look for them feeding in flocks in fruiting trees, particularly in secondary forests, plantations and moist deciduous woodlands where they select favoured fruiting trees repeatedly.

Photography Tips

The Oriental Pied Hornbill's striking black and white plumage and distinctive casque make it a rewarding photographic subject. The sexual dimorphism—particularly the males' bright red eyes and yellow bills contrasting with females' brown-patched bills—offers good opportunities for comparative shots. When photographing, focus on fruiting trees during non-breeding season flocking behaviour, and watch for their characteristic crowlike calls and harsh screeches to locate feeding birds in the canopy. The white-tipped tail feathers and white underwings create strong compositional elements in flight photographs.
