Nelapattu: Southeast Asia's Premier Spot-Billed Pelican Breeding Sanctuary

Ecological Stature: One of Southeast Asia's Largest Pelicanries

Located in Doravarisatram mandal of Tirupati district, just 18 kilometers north of Sullurpeta, Nelapattu Bird Sanctuary (officially designated as Nelapattu Wildlife Sanctuary in 1997) is universally recognized by international conservation bodies as one of the most vital avian breeding habitats in Asia. The sanctuary spans a total protected area of 458 hectares, centered on an 82-hectare seasonal freshwater irrigation tank surrounded by dry-evergreen scrub forest.

Nelapattu holds global conservation prominence as one of the largest communal breeding colonies (pelicanries) of the Spot-Billed Pelican (Pelecanus philippensis) on earth. The species, listed as Near Threatened by the IUCN, finds an extraordinary natural sanctuary here, with annual breeding populations exceeding 1,500 individuals.

The sanctuary functions in close ecological symbiosis with nearby Pulicat Lake (located just 15 km away): pelicans, storks, and egrets build their nests and raise their young on the safe freshwater trees of Nelapattu, while making daily foraging flights to feed on the rich marine fish and shrimp of the Pulicat brackish lagoon.

Botanical Habitat: The Water-Loving Barringtonia Swamp Trees

The ecological linchpin of Nelapattu is the dense forest of Barringtonia acutangula trees that grow directly within the shallow waters of the freshwater tank. These water-tolerant trees possess extraordinary adaptations, flourishing with their lower trunks and root systems submerged beneath three to five feet of water for over six months each year.

As the monsoon fills the tank between October and November, thousands of waterbirds converge on these semi-submerged trees. A single large Barringtonia tree often hosts dozens of distinct nests belonging to multiple species: Spot-Billed Pelicans occupy the uppermost central boughs, Painted Storks build platform nests on intermediate branches, while Asian Openbills, Little Cormorants, and Night Herons claim the lower foliage.

The cooperative multi-species nesting creates a bustling, lively avian metropolis where the calls of chicks, the clattering of stork bills, and the whoosh of pelican wings fill the forest air.

Avian Census: Resident Breeders and Winter Visitors

Over 180 species of birds have been documented at Nelapattu, including both colonial nesting waterbirds and winter migrants from the northern hemisphere. In addition to pelicans and painted storks, the heronry supports large breeding colonies of White Ibis (Black-headed Ibis), Glossy Ibis, Darter (Snakebird), Little Egret, Intermediate Egret, Cattle Egret, and Grey Heron.

The open water areas are filled with whistling ducks, common teals, garganeys, and northern pintails. The surrounding terrestrial dry evergreen scrub provides habitat for woodland birds including the Indian roller, Asian paradise flycatcher, spotted owlet, golden oriole, and various species of cuckoos.

A designated deer park within the sanctuary compound houses a thriving herd of spotted deer (chital), which can be seen grazing peacefully beneath towering banyan and tamarind trees near the visitor pathways.

Visitor Infrastructure: Watchtowers, Interpretation Center, and Walking Trails

The Andhra Pradesh Forest Department has developed exemplary eco-tourism infrastructure at Nelapattu that facilitates world-class birdwatching while minimizing ecological disturbance. Well-paved, shaded walking paths skirt the southern embankment of the freshwater tank.

Several elevated multi-story observation watchtowers are strategically positioned along the tree line, equipped with high-powered spotting scopes and binoculars that allow visitors to look directly into pelican nests at eye level without disturbing the birds. Interpretive signage along the trails illustrates bird identification keys, migration routes, and ecological life cycles.

The sanctuary entrance houses a modern Environmental Interpretation Center, a library, an audio-visual screening theater, and clean restroom facilities, making it an exceptional educational destination for school groups, families, and professional ornithologists.

Transit Gateways, Road Logistics, and Regional Hubs

Nelapattu is situated along National Highway 16 (the Chennai-Kolkata highway), approximately 18 km north of Sullurpeta and 50 km south of Gudur. Doravarisatram is the local village access point located 3 km from the sanctuary gate.

Sullurpeta Railway Station (SPE, 18 km) and Nayudupeta Railway Station (NYP, 20 km) on the Chennai-Vijayawada mainline provide frequent express rail access. Chennai International Airport (MAA) is situated 105 km to the south (about a 2 to 2.5-hour drive along the smooth expressway).

APSRTC buses running between Chennai, Sullurpeta, and Nayudupeta stop on request at the Nelapattu highway junction. Taxis and auto-rickshaws can be easily chartered from Sullurpeta for half-day excursions, frequently combined with an afternoon visit to Pulicat Lake.

Community-Based Conservation and Field Etiquette

Nelapattu stands as an inspiring global model of community-based wildlife conservation. For generations, the villagers of Nelapattu and surrounding hamlets have fiercely protected the nesting birds, considering the arrival of pelicans an auspicious herald of good monsoon rains and bountiful agricultural harvests.

Villagers strictly forbid hunting, tree cutting, or setting off firecrackers during Diwali in the vicinity of the sanctuary to prevent scaring the birds, demonstrating centuries of indigenous ecological coexistence.

Visitors must strictly honor this legacy by keeping noise to an absolute minimum, depositing all plastic and food waste in bins outside the sanctuary, and strictly refraining from throwing stones or disturbing roosting birds.
