Kanjirankulam Bird Sanctuary

Set amid the flat thorn-scrub farmland of inland Ramanathapuram district, Kanjirankulam Bird Sanctuary is one of the small tank-fed reserves that make this corner of Tamil Nadu a quiet joy for birdwatchers.

• It protects a shallow irrigation tank ringed by babul and Prosopis scrub near the town of Mudukulathur, about 40 km — an hour's drive — west of Ramanathapuram town, and roughly 100 km, or two to two and a half hours, from Rameswaram island.
• Notified as a bird sanctuary in 1989 and listed as a Ramsar Wetland of International Importance in 2022 alongside Chitrangudi and several other Tamil Nadu tank sanctuaries, its roughly 1.04 sq km of water and low canopy comes alive after the northeast monsoon, when the tank fills and thousands of waterbirds gather to feed and breed.
• It is a modest, unshowy place — no gates, ticket counters or crowds — where the reward is patience, a pair of binoculars and the slow theatre of a nesting colony.
• The breeding season is the reason to come.
• Painted storks build their untidy stick nests in the scrub trees, several to a crown, their pink-tinged wings unmistakable against the dry-country sky.
• Sharing the colony are black-headed ibises, Eurasian spoonbills sieving the shallows with their spatula bills, and a shifting cast of grey and purple herons, egrets, open-billed storks, cormorants and darters; winter also brings migratory ducks, teals and waders to the open water.
• As at other Tamil Nadu tank sanctuaries, the surrounding farming villages have generally lived alongside the colonies rather than driving them off — nutrient-rich runoff from the roosts is valued on the fields.
• Walk the earthen tank bund slowly at dawn or in the golden hour before dusk, stay well back from the nesting trees, and let the birds settle rather than flushing them for a photograph.
• The sanctuary pairs naturally with the nearby Chitrangudi tank sanctuary, and the two together make an easy inland detour for anyone wanting to trade temple corridors and coastline for open sky.
• Facilities are minimal — no interpretation centre, no real watchtower, no shops — so carry water, a hat, sun protection and your own food, and budget the better part of a day of driving if you are setting out from Rameswaram.
• For meals, plan to eat in Ramanathapuram town or Mudukulathur; there is nothing at the tank itself.
• Ramanathapuram's bazaar streets have small, unbranded South Indian 'meals' hotels that serve unlimited banana-leaf thalis at lunch and idli, dosa, pongal, vadai and filter coffee from early morning, while simple tiffin stalls in Mudukulathur cover breakfast and evening snacks.
• This is a coastal district where fishing is a mainstay and many kitchens are mixed, so the safest habit is to look for an explicitly pure-vegetarian board at the door and confirm at the counter before you order.
• Sweet shops, tiffin stalls and 'meals' hotels that advertise pure veg are the dependable options, and a packed picnic is wiser still if you plan a long morning among the birds.
