What Happened
- The Chhattisgarh Forest Department is establishing six "hornbill restaurants" within the Udanti Sitanadi Tiger Reserve (USTR) in Gariaband district — designated forest patches enriched with fruit-bearing trees to sustain the Malabar Pied Hornbill.
- The Malabar Pied Hornbill (Anthracoceros coronatus), traditionally associated with the moist forests of the Western Ghats, was first documented in USTR in 2017. Its presence has grown steadily — by 2023, sightings occurred once or twice a month; currently, one or two individuals are spotted almost every week.
- The "restaurant" concept involves planting and nurturing fig trees (Ficus species) and other fruiting species that form the primary diet of hornbills, creating reliable food-source patches that encourage sustained habitation and breeding.
- The initiative also aims to support natural forest expansion by leveraging the hornbill's unique ecological role as a keystone seed disperser.
- USTR is also notable for hosting other Western Ghats species beyond their traditional range — making it an emerging biodiversity hotspot in central India.

Malabar Pied Hornbill — Ecology and Conservation Status
The Malabar Pied Hornbill is one of India's nine hornbill species and is distinguished by its distinctive black-and-white plumage, large casque (hollow projection on the bill), and obligate dependence on old-growth forest with large-diameter trees for nesting. Its conservation status and ecological role make it a significant indicator species for forest health.
- Scientific name: Anthracoceros coronatus.
- IUCN Red List status: Near Threatened (2024 assessment); global population estimated at 3,000–32,000 mature individuals.
- Range: Traditionally, the Western Ghats and Sri Lanka; found in moist deciduous and evergreen forests.
- Nesting behaviour: Hornbills nest in natural tree hollows; the female seals herself inside with mud and droppings during incubation, relying entirely on the male for food. This makes them vulnerable to tree-felling and hollow-tree scarcity.
- Diet: Primarily frugivorous (fruit-eating), especially figs; also takes insects, small vertebrates.
- Protected under: Schedule IV of the Wildlife Protection Act, 1972 (India).
Connection to this news: The "hornbill restaurant" concept directly addresses the primary threat — food availability — by artificially enriching habitat quality in a reserve where the species is newly establishing itself beyond its traditional range.
Hornbills as Keystone Seed Dispersers
Hornbills play a disproportionately important role in forest ecosystem functioning relative to their population size — the defining characteristic of a keystone species. Their seed dispersal services are essential for the regeneration of large-seeded tree species, particularly in tropical forests.
- Hornbills ingest large fruits whole, fly considerable distances (up to several kilometres), and deposit seeds in their droppings — facilitating seed dispersal for plant species unable to disperse their seeds by wind or smaller animals.
- Key tree species dependent on hornbills for dispersal include Myristica (nutmeg family), Polyalthia, and large-seeded Ficus varieties.
- In fragmented forests, the loss of hornbills leads to "ecological extinction" of large-seeded plant species even before the plant itself disappears — a phenomenon called "empty forest syndrome."
- Other keystone seed dispersers in Indian forests: elephants (for even larger-seeded species), fruit bats, and large frugivorous primates.
Connection to this news: By establishing hornbill restaurants to sustain a growing hornbill population at USTR, the Forest Department is not merely conserving a bird species — it is actively maintaining a critical ecosystem service that supports forest self-renewal across the tiger reserve.
Udanti Sitanadi Tiger Reserve and the Tiger Reserves Network
Udanti Sitanadi Tiger Reserve (USTR) is one of India's designated tiger reserves under Project Tiger, located in the Gariaband district of Chhattisgarh. It is significant both for its tiger conservation mandate and for its biodiversity value as a transitional zone between the Deccan Peninsula and central Indian forests.
- Area: USTR covers approximately 1,842.54 sq km (core: 1,093.32 sq km; buffer: 749.22 sq km).
- Established as a Tiger Reserve under Project Tiger in 2009.
- Location significance: USTR lies at the ecological transition between the Eastern Ghats and the Deccan Plateau, supporting species from multiple biogeographic zones — including, as recently documented, species associated with the Western Ghats.
- Wildlife: Wild buffalo (Bubalus arnee) — USTR is one of the last refuges of the wild gaur and the Indian gaur; also home to leopards, sloth bears, giant squirrels, and the newly documented Malabar Pied Hornbill.
- Project Tiger: Launched 1973; currently 57 tiger reserves across 18 states; administered by the National Tiger Conservation Authority (NTCA) under the Ministry of Environment, Forest and Climate Change (MoEFCC).
Connection to this news: The hornbill restaurant initiative illustrates how tiger reserves, originally conceived for a single flagship species (tiger), increasingly function as multi-species biodiversity conservation landscapes — justifying the broader "landscape conservation" approach now embedded in India's wildlife management philosophy.
