Bundala Wildlife: What You Will Actually See

Bundala is the shorebird park, and it is the reason serious birders come to the south coast at all. A Ramsar wetland of brackish lagoons, salt pans and thorn scrub, it takes the migrant waders that have crossed most of Asia to get here, and between September and March the lagoon margins carry numbers you will not see anywhere else on the island.

Greater flamingos are the birds people photograph, standing in the shallow pans in loose pink lines. Behind them sit the ones worth knowing about: the crab-plover, a strange black and white wader with a bill built for the job its name describes, and the great thick-knee on the dry margins with an eye like a headlamp.

Bundala is also a reptile park that nobody markets as one. Mugger crocodiles hold the lagoon channels, star tortoises walk the scrub after rain, and the coastal sand at Palatupana carries Bahir’s fan-throated lizard, an endangered endemic that lives on a thin strip of shore and almost nowhere else. Five sea turtle species use this coast, and the leatherback is on the list because it does come ashore here, not because you will meet one.

Planning

September to March is the window, because that is when the migrants are in. Early morning for the light on the pans and for the waders before the heat moves them. Bring a scope or accept that a lot of this is distant: these are open lagoons and the birds are out on them. The scrub between the lagoons is where the reptiles are, and it is worth walking the track edges rather than driving past them. Bundala sits immediately west of the busiest stretch of the south coast and its water levels are managed rather than natural, so numbers swing between years. Take the salt pans seriously in the heat, because there is no shade at all.

Frequently asked questions

What birds can you see at Bundala?

Greater flamingo, spot-billed pelican, Eurasian spoonbill, black-headed ibis, crab-plover and great thick-knee are the headline waterbirds, with cotton pygmy goose and bronze-winged jacana on the fresher lagoons and pallid harrier over the scrub.

When is the best time to visit Bundala?

September to March, when the migrant waders are in. Outside that window the resident waterbirds and the reptiles carry the park, which is a quieter and much less crowded trip.

Can you see flamingos in Sri Lanka?

Yes. Bundala is the most reliable southern site, with birds on the salt pans through the northern winter. Mannar and the Jaffna lagoons in the north hold larger numbers.

Is Bundala worth visiting if you are not a birder?

It is a thinner trip than Yala if you want big mammals, and a better one if you want reptiles and landscape. Mugger crocodile, star tortoise, monitor lizards and the coastal fan-throated lizard are all here, and the park is far quieter.
