Quick answer
Vankalai Sanctuary, on the mainland shore opposite Mannar Island, is a Ramsar wetland of roughly 4,800 hectares and one of the best places in Sri Lanka for migrant waterbirds. From roughly November to March it holds greater flamingos, thousands of waders such as sandpipers, plovers and stints, and ducks, terns and gulls. Mannar is roughly three hours from Anuradhapura and two from Jaffna by road, and nearby Giant's Tank and the island's salt flats add to the birding.

What Vankalai Sanctuary is
Vankalai Sanctuary lies on the mainland side of the Mannar causeway, in the Mannar district of north-western Sri Lanka. It was declared a sanctuary in 2008 and designated a Ramsar wetland in 2010. It protects shallow lagoons, mudflats, salt marsh, seagrass beds and thorny scrub along the coast.
Mannar sits at the end of the Central Asian Flyway, one of the main routes migratory birds use to travel between their northern breeding grounds and South Asia. When they arrive after the long flight, the shallow, food-rich waters of Mannar are among the first places they rest and feed.
Birds of Vankalai and Mannar
Vankalai's headline birds are greater flamingos, which can gather in hundreds or more in the shallow lagoons in some seasons. They are joined by thousands of migrant waders, including sandpipers, stints, plovers, godwits, curlews and redshanks, along with terns, gulls and ducks.
Resident birds include painted storks, spoonbills, herons, egrets and pelicans, and the scrub has larks, bee-eaters and the occasional raptor. Numbers and species vary from year to year, depending on water levels and rainfall.

Birding around Mannar
Mannar Island and the surrounding mainland offer several birding sites besides Vankalai. Giant's Tank, an ancient reservoir south-east of Mannar, holds large numbers of ducks, cormorants and waterbirds. The salt flats and lagoons on Mannar Island near Talaimannar attract waders and flamingos, and the coastal scrub has larks and bee-eaters.
The island also has the famous baobab tree, said to have been planted by Arab traders centuries ago, and the Adam's Bridge sandbanks stretching towards India, which can be seen from Talaimannar.
- →Giant's Tank: ducks and waterbirds.
- →Talaimannar salt flats: waders and flamingos.
- →Mannar's baobab: a curiosity on the island.
When to visit
The best time to visit Vankalai Sanctuary is roughly November to March, when migrant birds are present in their greatest numbers. December to February is often the peak. From roughly April, migrants leave for their northern breeding grounds, and numbers fall sharply.
The north-east monsoon, roughly November to January, brings rain to the north, so there can be wet days early in the season. Mornings are best for birding and photography, as the light is soft and the heat builds by midday.
- →November to March: migrant season.
- →December to February: often the peak.
- →April to October: residents only, far fewer birds.

Who Mannar suits
