Birdlife: hornbills, sea eagles and swiftlets

Summary

Koh Samui's forests, gardens and coasts hold tropical birdlife including oriental pied hornbills, white-bellied sea eagles and the swiftlets whose nests are harvested on the Five Islands.

Details

For a developed island, Samui still offers rewarding casual birdwatching. Local nature guides list the oriental pied hornbill as common in the forested interior and along canopy edges - a large black-and-white bird with a huge yellow-and-black bill, usually seen in pairs in the morning. White-bellied sea eagles patrol the coasts and are sometimes seen even over busy beaches like Bophut. Gardens and flowering trees attract sunbirds and other small nectar feeders, and red-whiskered bulbuls are so popular locally that bird-singing competitions are held on the island. Offshore, the Five Islands (Koh Si Koh Ha) host large nesting colonies of swiftlets; their nests are harvested under private concessions for bird's nest soup and are guarded, which is why landing there is restricted. Ang Thong Marine Park has its own island ecosystem with sea eagles, kingfishers and other coastal species, making a boat day trip there doubly interesting for birdwatchers. Best times are early morning and late afternoon; bring binoculars for sea-watching.

Safety and ethics

Watch birds without disturbing them; never approach nests; do not use recorded bird calls near nesting areas; respect the protected swiftlet concessions on the Five Islands (no landing, no drones).

Frequently asked questions

Can you see hornbills on Koh Samui?

Yes, local guides report oriental pied hornbills as common in the island's forested interior. Early morning is the best time.

What birds can I see without leaving the beach?

White-bellied sea eagles are sometimes seen over beaches such as Bophut, plus kingfishers, herons and garden birds like sunbirds.

Why can't I visit the bird islands off Taling Ngam?

The Five Islands are private swiftlet-nest concessions. The nests are valuable (used for bird's nest soup) and are guarded, so landing is restricted to protect the birds and the harvest.
