The Malabar pied hornbill (Anthracoceros coronatus) is a large black-and-white forest bird of peninsular India and Sri Lanka, recognised by its heavy yellowish bill topped with a hollow casque and by the remarkable nesting habit in which the female is sealed inside a tree cavity until the chicks are partly grown. It belongs to the hornbill family, Bucerotidae, and is one of the nine hornbill species recorded in India.
Unlike the better-known great hornbill, the Malabar pied hornbill is a bird of foothill forests, moist deciduous woodland, forest edges and even well-wooded plantations and large village trees. It is noisy, social and easy to notice once its raucous calls and heavy wingbeats are known. This article explains how to identify the species, where it lives in India, what it eats, how it breeds, why it matters to forests and what threatens it.

What is the Malabar pied hornbill?
The Malabar pied hornbill is a medium-to-large hornbill in the genus Anthracoceros, a group of pied (black-and-white) hornbills found in South and South-East Asia. The word “pied” refers to the contrast between its glossy black body and its white belly and tail edges, while “Malabar” points to the Malabar coast of the south-west, the region of the Western Ghats that forms the core of its Indian range.
For many years the Malabar pied hornbill was considered a regional form of the Oriental pied hornbill (Anthracoceros albirostris), which ranges from the Himalayan foothills and north-eastern India across South-East Asia. Later work on differences in appearance, voice and distribution led most authorities to treat the peninsular Indian and Sri Lankan birds as a separate species. In practice, the two never meet in India: one occupies the peninsula, the other the north-east.
Like all hornbills, the Malabar pied hornbill has a long, down-curved bill, a long tail, strong feet and a heavy, slightly awkward flight. It is not a close relative of toucans, although the large bill has led to the two groups being compared. Hornbills belong to an Old World lineage, while toucans are New World birds, and the similarity arises from convergent evolution towards a fruit-eating lifestyle.
How can you identify a Malabar pied hornbill?
A Malabar pied hornbill can be identified by its black upper body, white belly, white outer tail feathers and a large pale yellow bill with a prominent casque that carries a black patch near the front. The bird is about the size of a large crow with a much longer tail, and its profile in flight, with a long neck, large bill and trailing tail, is unmistakable.
Plumage
The head, neck, back and wings of the Malabar pied hornbill are glossy black, sometimes with a faint greenish sheen in good light. The belly and vent are white, and the tips of the outer tail feathers and the trailing edge of the wing show white. These pale patches become obvious when the bird flies from one fruiting tree to another, so that a pair seen in flight appears as a flicker of black and white.
Bill and casque
The massive bill is yellowish-white to ivory, and the casque on top of the upper mandible is large, flattened and blunt-ended, with a dark patch on the front. A ring of bare skin around the eye gives the face a distinctive look. Despite its size, the bill is light in weight because both the bill and casque are largely hollow and internally supported by thin bony struts.
Males and females
The sexes look broadly similar, which is common among hornbills. Males tend to be slightly larger, with a bigger bill and casque, and the eye colour and bare-skin details can differ between sexes, but separating the two usually requires close views. Young birds look duller, with a smaller casque that grows as the bird matures.
Similar species
- Oriental pied hornbill: found in north-eastern India and eastwards; slightly different casque and bill markings, and a separate range.
- Great hornbill: much larger, with a bold yellow casque and a yellow-and-black bill, found in wetter forests of the Western Ghats, the Himalayan foothills and the north-east.
- Malabar grey hornbill and Indian grey hornbill: smaller and mainly grey-brown rather than black and white.
Where does the Malabar pied hornbill live in India?
The Malabar pied hornbill lives mainly along the Western Ghats and the adjoining peninsular forests of India, from the southern Gujarat and Maharashtra region through Goa and Karnataka to Kerala and Tamil Nadu, with additional populations in parts of the Eastern Ghats and hill ranges of the peninsula. The exact limits of its range shift as forest cover changes, so the bird is better described as patchily distributed than uniformly common.
The species prefers lower and middle elevations. It is most often found in moist deciduous and semi-evergreen forests, along forest edges, in river valleys and in areas where wild fig trees (Ficus species) are common. It is less dependent on dense evergreen interior forest than the great hornbill, which gives it a greater ability to persist near human settlements as long as tall fruiting and nesting trees remain.
The bird also occurs in Sri Lanka, which is why it is usually described as a species of peninsular India and Sri Lanka rather than of India alone. Within India, notable places where birdwatchers record it include the forests of the Western Ghats in Maharashtra, Goa, Karnataka and Kerala, as well as several protected areas of the peninsula, though records vary from season to season.
Seasonal movements
Malabar pied hornbills are largely resident, but they move locally in search of ripe fruit. A fig tree in fruit can draw groups of hornbills from some distance, and birds may abandon an area when the fruit is finished. These movements are short and follow food, not fixed migration routes.
What does the Malabar pied hornbill eat?
The Malabar pied hornbill eats mainly wild fruit, with figs forming the most important part of its diet, and it supplements this with insects, lizards, small reptiles and occasionally the eggs or young of other birds. The proportion of animal food rises during the breeding season, when the female and chicks need more protein.
The bird picks fruit with the tip of its bill, tosses its head back and swallows the fruit whole. This feeding technique allows it to handle fruit that is large relative to the bill, and the bill’s length also lets the bird reach fruit at the end of thin branches that would not support its body weight. Seeds are later regurgitated or passed in droppings, often at some distance from the parent tree.
Fruiting trees important to hornbills include several fig species, as well as laurels, nutmegs and other forest trees whose fruit is rich in fat or sugar. Insects such as large beetles, grasshoppers and cicadas are caught among the branches or on the ground, and lizards may be pulled out of bark crevices. In plantations, the bird sometimes visits fruiting trees near coffee and arecanut estates, where it is usually tolerated.
How does the Malabar pied hornbill breed and nest?
The Malabar pied hornbill breeds in a natural tree cavity in which the female is walled in with a plaster of mud, droppings and fruit pulp, leaving only a narrow vertical slit through which the male passes food. The breeding season generally falls in the drier months, from late winter into early summer, though timing varies with locality and food supply.
The sealed nest
The pair chooses a large cavity, often in a tall mature tree with a hollow trunk. The male and female inspect several sites before settling on one. Once the female enters, she uses material brought by the male, along with her own droppings, to narrow the entrance until only a slit remains. This seal protects the nest from snakes, monitor lizards, squirrels and other predators.
Egg laying and incubation
The female lays a small clutch of white eggs, often two or three, inside the cavity and incubates them without leaving. During this period she depends completely on the male, who may make dozens of trips each day, carrying fruit and other items in the tip of his bill or in his throat and passing them to her through the slit.
Moulting and fledging
The female moults her flight feathers while confined, which means she is flightless during part of the nesting period. After the chicks hatch, she eventually breaks out of the cavity, and in many hornbill species the chicks then reseal the entrance and are fed by both parents until they are ready to leave. The whole cycle lasts several weeks, and nests are vulnerable at every stage: if the male is lost, the female and chicks may starve.
What is the casque on a Malabar pied hornbill for?
The casque on a Malabar pied hornbill is a hollow, horn-covered structure on top of the upper bill whose exact function is still debated, with leading explanations being a visual signal of age and sex, a resonating chamber that may amplify calls, and a feature of mate choice. In some other hornbills, such as the helmeted hornbill of South-East Asia, the casque is solid and used in aerial combat, but in the pied hornbills it is largely hollow and relatively light.
Because males typically have larger casques than females, and young birds have small ones, the casque is thought to function as an indicator of maturity and condition. Researchers have also suggested that it may play a role in vocalisation, but evidence for strong amplification in pied hornbills remains limited. It is better to treat the casque as a prominent ornament whose purpose may combine several roles.
Why is the Malabar pied hornbill important for forests?
The Malabar pied hornbill is important for forests because it disperses the seeds of many fruiting trees, particularly large-seeded species that smaller birds cannot swallow, and its presence indicates that old, fruit-bearing and cavity-bearing trees are still standing. Ecologists often describe hornbills as “forest gardeners” for this reason.
Seed dispersal by hornbills helps forest trees colonise new gaps and regenerate after disturbance. Because hornbills fly long distances between fruiting trees, they carry seeds well away from the parent tree, where seedlings are less likely to be eaten by pests or crowded by siblings. This movement connects fragments of forest in a way few other animals can.
The bird is also a useful indicator species. Hornbills require large, old trees for nesting, and such trees take many decades to develop cavities. When hornbills disappear from a forest, it often means that selective logging, clearing for plantations or fragmentation has removed these key trees. Monitoring hornbill numbers therefore provides a rough measure of forest condition.
What is the conservation status of the Malabar pied hornbill?
The Malabar pied hornbill is listed as Near Threatened on the IUCN Red List, which means it is close to qualifying for a threatened category because of ongoing habitat loss and fragmentation. Its numbers are not as low as those of some Asian hornbills, but its dependence on mature trees makes it sensitive to changes in land use.
In India, hornbills are protected under the Wildlife (Protection) Act, 1972, and the family is also listed under the Convention on International Trade in Endangered Species (CITES) to regulate trade. Hunting and capturing the birds, or taking eggs and chicks, is prohibited.
Main threats
- Loss of nesting trees: felling of large, hollow trees removes the cavities hornbills need for breeding.
- Forest fragmentation: roads, plantations, mining and settlements break up forest and reduce the number of fruiting trees available.
- Hunting and capture: in some regions, hornbills are hunted for meat, casques or for the pet trade, though this pressure is more severe on larger species.
- Disturbance at nests: collection of firewood, tree-cutting and honey collection near nest trees can cause failure.
- Loss of fig trees: clearing of fruiting trees in farms and roadsides reduces food in the lean season.
Conservation action
Community-based nest protection has helped hornbills in several parts of India, where local people are engaged to monitor nests and protect nest trees. Artificial nest boxes have been tried for some hornbill species, with variable success. Protecting old trees outside reserves, including trees on private land and village groves, is considered one of the most practical measures for the Malabar pied hornbill.
How does the Malabar pied hornbill compare with other Indian hornbills?
The Malabar pied hornbill is a mid-sized, adaptable hornbill that differs from other Indian species in size, range and habitat, and the table below summarises the main differences. India’s nine hornbill species range from the small grey hornbills of dry country to the huge great hornbill of wet forest.
| Species | Approximate size | Typical range in India | Notes |
|---|---|---|---|
| Malabar pied hornbill | Medium-large | Western Ghats and peninsular forests | Black and white; hollow casque; Near Threatened |
| Oriental pied hornbill | Medium-large | North-east India and Himalayan foothills | Close relative; separate range |
| Great hornbill | Very large | Western Ghats, Himalayan foothills, north-east | Bright yellow casque; Vulnerable |
| Indian grey hornbill | Medium | Much of mainland India, including towns | Grey-brown; often seen in city trees |
| Malabar grey hornbill | Medium | Western Ghats and southern hills | Grey with a pale bill; forest-dwelling |
| Wreathed hornbill | Large | North-east India | Wrinkled throat pouch in males |
| Rufous-necked hornbill | Large | Eastern Himalaya and north-east | Rufous head and neck in males |
| Brown hornbill | Medium | North-east India | Social; lives in groups |
| Narcondam hornbill | Medium-large | Narcondam Island, Andaman Sea | Found only on one small island |
The comparison highlights how the Malabar pied hornbill occupies a middle ground: more widespread and more tolerant of modified habitat than the great hornbill, yet more forest-dependent than the Indian grey hornbill, which regularly nests in the avenues of towns and cities.
How can you watch Malabar pied hornbills responsibly?
Malabar pied hornbills are best watched from a distance near fruiting fig trees in the early morning or late afternoon, using binoculars and staying quiet, because the birds are wary during nesting. Responsible observation matters more for hornbills than for most birds, since a disturbed nest can fail completely.
- Visit fruiting fig trees in forest edges and wooded valleys, where groups gather to feed.
- Listen for loud, cackling calls and the heavy whooshing of wingbeats, which often announce the birds before they appear.
- Keep well away from any nest tree with a sealed entrance, and never play recorded calls repeatedly near a nest.
- Avoid using flash photography or approaching on foot close to nest trees during the breeding season.
- Report sightings to citizen-science platforms so that population and range data improve.
The bird is a good species for beginners because it is large, visible and vocal. It also offers a chance to learn about forest ecology, since the fig trees on which it depends support many other birds and mammals at the same time.
Bottom Line
The Malabar pied hornbill is a striking black-and-white seed disperser of peninsular India’s forests, notable for its sealed nest and its dependence on old fruiting trees. Protecting large trees, forest corridors and nesting sites is the most effective way to keep the species secure.
