Koonthankulam Bird Sanctuary, in Nanguneri taluk of Tirunelveli district, Tamil Nadu, is a wetland built around two village irrigation tanks where local residents have protected nesting water birds for generations. It is described by the Ramsar Secretariat as the largest reserve for breeding resident and migratory water birds in South India. This guide covers the breeding colonies and the village conservation tradition, the key species and their nesting season, the watchtower and visit arrangements, the best season, how to reach the sanctuary from Tirunelveli and the wider region, entry and permits, where to stay, a budget and the rules.
Koonthankulam Bird Sanctuary is a 129.33-hectare freshwater wetland in Tirunelveli district, Tamil Nadu, formed by the Koonthankulam and Kadankulam irrigation tanks. Declared a sanctuary in 1994 and a Ramsar site in November 2021, it is protected mainly by the Koonthankulam village community and is best visited between December and June, when breeding and migratory water birds gather.
Key takeaways
- Koonthankulam Bird Sanctuary lies in Koonthankulam village, Nanguneri taluk, Tirunelveli district, Tamil Nadu, about 35–38 km south of Tirunelveli on the Tirunelveli–Thisayanvilai road (per the Ramsar management plan and the Tirunelveli district administration).
- The Ramsar Sites Information Service calls it the largest reserve for breeding resident and migratory water birds in South India; it was declared a sanctuary in 1994 and a Ramsar site on 8 November 2021 (Ramsar site no. 2479).
- More than 43 species of resident and migratory water birds visit, and a field study records painted storks nest-building from mid-December, with chicks fledging by about mid-March (Tamil Nadu Agricultural University; Indian Forester, 2021).
- The village is the protector: residents guard nests, run a rescue centre for fallen chicks, and do not burst Diwali crackers so as not to frighten the birds (per Wikipedia and the Tirunelveli district site).
- It is the only traditional nesting colony of the spot-billed pelican, a tradition the Ramsar management plan says has existed for well over a century.
- Facilities include an interpretation centre, a watchtower, a children’s park and a dormitory, open through the year; the nearest railhead is Nanguneri, about 19 km away (per the Ramsar management plan, as of October 2026).
About Koonthankulam Bird Sanctuary: quick facts
Koonthankulam Bird Sanctuary is a 129.33-hectare protected wetland in Koonthankulam village, Nanguneri taluk, Tirunelveli district, Tamil Nadu, made up of two linked irrigation tanks, Koonthankulam and Kadankulam. According to the Ramsar Sites Information Service, the two tanks sit next to each other, joined by a tar road, and were declared a wildlife sanctuary in 1994.
The tanks are not wild lakes but working village reservoirs in the Thamiraparani canal system, which is why the birds and the farmers share the same water. The Ramsar listing records the site as an Important Bird Area (code IN269) and, on 8 November 2021, as Ramsar site no. 2479. It is classed as an IUCN category IV protected area.
What sets Koonthankulam apart is the arrangement that protects it. The sanctuary is managed with the active involvement of the Koonthankulam village community, alongside the Tamil Nadu Forest Department and the state Water Resources Department, which looks after the tanks. Sources differ slightly on figures, so the table below gives the commonly cited numbers with their caveats.
| Location | Koonthankulam village, Nanguneri taluk, Tirunelveli district, Tamil Nadu |
|---|---|
| Area | 129.33 hectares (1.2933 sq km); the Ramsar information sheet cites a smaller figure in one place, so treat the exact area as approximate |
| Declared sanctuary | 1994 |
| Ramsar site | No. 2479, designated 8 November 2021 |
| Managed by | Koonthankulam village community with the Tamil Nadu Forest Department and Water Resources Department |
| Known for | Breeding painted storks, spot-billed pelicans, ibises and flamingos; village-led protection |
| Coordinates | About 8.5810°N, 77.7612°E |
| Nearest railhead | Nanguneri, about 19 km (per the Ramsar management plan) |
| Best time | December–June, with nesting roughly December–March |
The birds: breeding colonies and migrants
More than 43 species of resident and migratory water birds visit Koonthankulam, according to Tamil Nadu Agricultural University’s forestry pages and the Ramsar listing. The headline breeders are the painted stork (a large white-and-pink wading stork with a yellow bill) and the spot-billed pelican, which the Ramsar management plan describes as having nested around the village for a very long period. The Ramsar sheet notes the sanctuary now holds about 15 nesting species, after some colonies shifted from village trees onto partly submerged Acacia stands in the tank.
Koonthankulam is, per the Ramsar management plan, the only traditional colony of the spot-billed pelican, a tradition it dates to well over a century ago. The plan also records how numbers can swing: about 1,000 spot-billed pelicans were counted in the early 1990s, but a January 2003 survey recorded only around 452 breeding, a reminder that colony size varies year to year.
The winter brings large numbers of migrants. The Ramsar listing states that more than 100,000 migratory birds arrive around December and leave for their northern breeding grounds by June or July, once the young can fly. The named migrants include the greater flamingo, bar-headed goose, northern pintail, common teal, common and green sandpiper, greenshank, coot and white stork, several linked to Siberia and Central Asia. The breeding ground is a Babul (Acacia nilotica, a thorny tank-side tree) plantation of about 30 hectares at Koonthankulam, grown in part by the Forest Department’s Social Forestry Division.
| Species | Status here | Notes |
|---|---|---|
| Painted stork | Breeding resident colony | Nest-building from mid-December; a headline nesting species |
| Spot-billed pelican | Breeding colony | Described as the only traditional colony, over a century old (management plan) |
| Ibises and herons | Breeding | Among the roughly 15 nesting species recorded |
| Greater flamingo | Migratory visitor | Among species named by the Ramsar listing |
| Bar-headed goose, northern pintail, common teal | Winter migrants | Arrive from around December; linked to Central Asia and Siberia |
| Sandpipers, greenshank, coot, white stork | Migrants and waterfowl | Part of the 43-plus water bird species that visit |
Nesting season: when the birds breed
The nesting season at Koonthankulam runs roughly from December to around March, which is different from the pure winter birding season elsewhere in India. A field study of painted storks carried out from October 2018 to May 2019, published in the Indian Forester in 2021, found that nest-building began in mid-December, soon after the northeast monsoon filled the tanks; egg-laying started in early January, most chicks hatched by mid-February, and the young fledged by about mid-March.
This timing matters for planning a visit. The birds breed after the rains rather than simply over-wintering, so the busiest, noisiest colonies — nests, eggs and chicks together — fall in the first months of the year. Migratory numbers overlap this window, with arrivals from about December and departures by June or July, per the Ramsar listing. Treat exact dates as weather-dependent: a weak or late monsoon can shift the whole cycle, so reconfirm the current nesting status locally before you travel (as of October 2026).
The village that protects the birds
Koonthankulam is protected chiefly by its own residents, a tradition both the Tirunelveli district administration and the Ramsar documents attribute to the village community rather than to fencing or gates. According to the Tirunelveli district site, villagers protect the birds, their nests and their young, and regard the birds that settle in their backyards as bringing good luck.
The protection is woven into daily life. Fallen chicks are taken to a rescue centre and cared for until they can fly, per the district administration and Wikipedia. The same sources note the village does not celebrate Diwali with firecrackers, so the noise does not scare nesting birds away. The district site adds that people who disturb nests face the villagers’ own sanctions.
The relationship is practical as well as protective. In the dry summer months, after the birds leave, residents collect the accumulated guano (bird droppings) mixed with tank silt and use it as fertiliser on their fields, which ties the community’s livelihood to the health of the colony. Local conservationists, among them a resident long known as the village “bird man”, have helped sustain the tradition and the rescue work. Please treat the village as a living community, not a spectacle — keep your distance from homes and nests.
Best time to visit
The best time to visit Koonthankulam Bird Sanctuary is December to June, with January to March the peak for seeing active nests, eggs and chicks. Tamil Nadu Agricultural University’s forestry page lists the season as January to July; the Ramsar listing has migrants arriving around December and leaving by June or July. The sanctuary is quietest and least rewarding from roughly August to November, when most birds have dispersed and the tanks may be low. The table sums up the year for planning.
| Period | Conditions | Notes |
|---|---|---|
| December–March | Cool to warm, tanks full after the monsoon | Peak nesting; painted storks and pelicans on eggs and chicks. Best overall. |
| April–June | Hot and dry | Fledglings and late migrants still present; the colony thins as birds leave. Carry water and go early. |
| July | Very hot; birds dispersing | Tail end of the season; numbers falling as the young depart. |
| August–November | Northeast monsoon builds (Oct–Dec) | Low season; few breeding birds until the tanks refill and the cycle restarts. |
How to reach Koonthankulam Bird Sanctuary
The usual way to reach Koonthankulam is by road from Tirunelveli, about 35–38 km north, with the final stretch into the village by hired car or taxi. The Ramsar management plan locates the sanctuary on the Tirunelveli–Thisayanvilai road in Nanguneri taluk and gives the distance from Tirunelveli as about 35 km; the Tirunelveli district site and Incredible India say about 38 km. From the southern towns, travellers coming from Nagercoil or Kanyakumari drive up via Nanguneri; no source gives an exact Nagercoil distance, so plan for a longer road leg and use live routing.
The nearest railway station is Nanguneri, about 19 km away, per the Ramsar management plan, while Tirunelveli Junction is the main railhead for long-distance trains. For a wider south Tamil Nadu trip, our Tamil Nadu travel guide helps you slot the sanctuary into a route, and our Madurai travel guide covers the nearest large city and transport hub to the north. Buses run frequently to Moolakaraipatti on the highway, from where you hire a vehicle; direct buses into Koonthankulam village are limited.
| From | Mode | Approx. distance / note |
|---|---|---|
| Tirunelveli | Car / taxi via Tirunelveli–Thisayanvilai road | About 35–38 km (sources differ) |
| Nanguneri (nearest railway station) | Taxi / local transport | About 19 km (Ramsar management plan) |
| Nearest airport | Car | Thoothukudi (Tuticorin) cited at about 70 km by the management plan; Madurai and Thiruvananthapuram are the larger airports — use live routing |
| Moolakaraipatti (highway town) | Bus, then hired car | Frequent buses; village roads are narrow — hire a driver who knows the way |
Sources conflict on the nearest airport — the management plan gives Thoothukudi at about 70 km, while a Tamil Nadu forestry page cites a much shorter 25 km — so confirm distances with a maps app before booking flights.
Watchtower, entry and visit arrangements
You watch the birds from a watchtower and marked points near the tanks rather than walking among the nests, and the core visitor facilities are open through the year. The Ramsar listing and TNAU record an interpretation centre, a watchtower, a children’s park and a dormitory on site. There are no roads inside the sanctuary; because the area is small it is covered on foot, per the management plan, so plan to walk the tank bunds quietly.
No official entry fee or fixed timing was found on the Tamil Nadu Forest Department or Tirunelveli district pages consulted. A third-party travel listing quotes about ₹10 entry and ₹50 for a camera, but this is unofficial and may be out of date (indicative — reconfirm, as of October 2026). Because the sanctuary sits inside a working village and the colonies are sensitive, it is best to contact the District Forest Officer, Tirunelveli, or ask the local forest watcher on arrival about current access, any guide arrangement and whether a particular tank is nesting that week.
| Entry fee | No official figure found; a third-party listing quotes about ₹10 (indicative — reconfirm) |
|---|---|
| Camera charge | About ₹50 per an unofficial listing (indicative — reconfirm) |
| Viewing | From the watchtower and tank bunds, on foot; no roads inside |
| Facilities | Interpretation centre, watchtower, children’s park, dormitory (open year-round) |
| Permits | No ILP/PAP required; contact the District Forest Officer, Tirunelveli, for access queries |
Where to stay
Most visitors stay in Tirunelveli, about 35–38 km away, which has the fullest range of hotels and the best transport links, and make Koonthankulam a half-day or morning trip. Both TNAU and the district sources point to Tirunelveli and Thoothukudi for hotels and a government tourist house. On site, the sanctuary dormitory is a simple option for birders who want to be there at dawn, and should be checked and booked ahead through the Forest Department, as capacity is limited.
Indicative room bands for a double in Tirunelveli, as of October 2026 (reconfirm):
- Budget: simple lodges and hotels in Tirunelveli town, roughly ₹1,000–₹2,000 a night.
- Mid-range: business and better city hotels, roughly ₹2,500–₹5,000.
- Government / on-site: the sanctuary dormitory and Tamil Nadu tourist accommodation — book ahead; basic facilities.
Because the colonies are most active soon after sunrise, an early start from Tirunelveli, or a night in the dormitory, is the most useful plan in the breeding months.
Budget breakdown
A visit to Koonthankulam is inexpensive, because any entry charge is small and the trip is usually a morning’s outing from Tirunelveli. The figures below are planning estimates for two people travelling from Tirunelveli by hired car for a half-day; the entry and camera charges are unofficial and must be reconfirmed, and transport depends on your choices.
| Item | Estimated cost | Notes |
|---|---|---|
| Entry (2 people) | About ₹20 | Indicative; unofficial listing of ~₹10 each — reconfirm |
| Camera charge | About ₹50 | Unofficial; skip if using a phone |
| Car hire (round trip) | ₹1,500–₹2,800 | Tirunelveli to the village and back, with waiting time |
| Local guide (optional) | ₹300–₹800 | Ask the forest watcher or village; supports the effort |
| Food and water | ₹300–₹700 | Carry water; eat in Tirunelveli or at Moolakaraipatti |
As a rough total, a half-day trip for two by hired car costs around ₹2,000–₹4,000, excluding your Tirunelveli hotel. Travelling by bus to Moolakaraipatti and sharing a car for the last stretch brings it down further. Treat these as planning figures and confirm any charges on the day.
Rules and practical tips
The one rule that matters most at Koonthankulam is to stay quiet and never disturb the nests, because the colony’s survival depends on the birds not being frightened off their eggs and chicks. This is a village-protected breeding sanctuary, not a zoo, so behave as a guest in both the wetland and the village.
- Keep quiet and keep your distance: no loud voices, music or horns near the tanks; watch from the watchtower and bunds, not under the nesting trees.
- Do not disturb nests or birds: never climb trees, throw anything to make birds fly, or use flash at the colony. Disturbing nests is taken seriously by the villagers.
- Respect the village: ask before photographing people or homes, and do not litter in the village or on the bunds; carry your waste out.
- No plastic and no feeding: do not feed the birds or leave plastic behind; single-use plastic is discouraged.
- Drones: do not fly drones over the colony — they panic nesting birds; seek written permission from the Forest Department first.
- Carry cash: the village and small stalls are cash-first; ATMs and reliable UPI are back in Tirunelveli or Nanguneri.
- Essentials: binoculars (the birds are across water, not close), sun protection, water, and sturdy shoes for the tank bunds.
- Nearest facilities: Tirunelveli (about 35–38 km) has the nearest full hospitals, pharmacies and services; Nanguneri is closer for basics.
Solo and women travellers generally find a daytime visit manageable given the village setting, but public transport to the village itself is thin, so arranging a known driver from Tirunelveli and travelling in daylight is the simplest and safest plan.
Nearby places
Koonthankulam pairs well with the temple towns and waterfalls of southern Tamil Nadu, so it fits into a Tirunelveli–Kanyakumari loop rather than a trip on its own. The distances below are indicative — reconfirm, as of October 2026.
| Place | Rough distance | Why go |
|---|---|---|
| Tirunelveli | About 35–38 km | The district city; temples, the Thamiraparani river and the famous halwa, plus the main railhead and hotels |
| Nanguneri | About 19 km | The Vanamamalai (Thothadri) Vishnu temple and the nearest railway station |
| Courtallam (Kutralam) | About 60–70 km | The season’s waterfalls in the Western Ghats foothills |
| Kanyakumari | About 80–90 km | India’s southern tip, where three seas meet; sunrise and sunset points |
For the wider region and how to string these together, our Tamil Nadu travel guide sets Koonthankulam alongside the state’s temples, hills and coast.

It is built around the Koonthankulam and Kadankulam irrigation tanks. The nearest railway station is Nanguneri, about 19 km away, per the Ramsar management plan.
What is the best time to visit Koonthankulam Bird Sanctuary?
The best time is December to June, and especially January to March, when painted storks and pelicans are on their nests with eggs and chicks. Tamil Nadu Agricultural University lists the season as January to July. Visit soon after sunrise for the most active colonies. From August to November most birds have dispersed, so the wetland is quiet.
Which birds nest at Koonthankulam, and when?
Painted storks, spot-billed pelicans, ibises, herons and other water birds nest here, among roughly 15 nesting species recorded by the Ramsar listing. A field study published in the Indian Forester (2021) found painted storks begin nest-building in mid-December, lay eggs in early January and fledge young by about mid-March, so breeding runs roughly December to March after the monsoon.
Why do the villagers protect the birds?
The Koonthankulam villagers protect the birds as a long tradition, regarding those that nest in their backyards as bringing good luck, according to the Tirunelveli district administration. They run a rescue centre for fallen chicks and avoid Diwali firecrackers so as not to scare the colony. In summer they collect guano and silt from the tanks to use as fertiliser.
Is there an entry fee or permit for Koonthankulam Bird Sanctuary?
No official entry fee or timing was found on the Forest Department or district pages, and no Inner Line or Protected Area Permit is needed. An unofficial travel listing quotes about ₹10 entry and ₹50 for a camera, which should be reconfirmed on arrival. For access and current nesting status, contact the District Forest Officer, Tirunelveli, or the local forest watcher.
How do I reach Koonthankulam from Tirunelveli?
Drive about 35–38 km south from Tirunelveli on the Tirunelveli–Thisayanvilai road, ideally by hired car or taxi, as direct buses into the village are limited.
