Iô Grande is a renowned bird-watching hotspot in the southern part of São Tomé island. This area, consisting of mangroves, river estuaries, and coastal forests, attracts an exceptional diversity of birds. It is particularly known for its waterbirds, herons, and kingfishers. Birdwatchers here can spot many of the island's endemic species, including the São Tomé paradise flycatcher and the São Tomé weaver. The mangroves of Iô Grande are not only important for birds but also serve as nurseries for fish and crustaceans and protect the coast from erosion. Guided tours with local experts are essential for finding and identifying the birds and understanding the complex ecological relationships. The protection of such areas is crucial for the conservation of São Tomé's unique avifauna.

📋 Practical info
Best season
The best months for birdwatching at Iô Grande are from July to December, when many migratory and endemic birds are active. During the rainy season (March-May) trails are tough, but bird diversity remains high.
Best time of day
Bird activity peaks in the early morning hours after sunrise, when birds are foraging. Late afternoon before sunset also features good chances to see many species.
Etiquette
Stay on marked trails to avoid disturbing vegetation and bird habitats. Avoid loud conversations and do not use bird calls, as they may stress the animals.
What to bring
A binocular with good magnification is important to spot birds in the trees and undergrowth. Lightweight, breathable clothing and sturdy hiking shoes are recommended as the terrain can be uneven.
Getting there
The bird watching site lies on the banks of the Rio Iô Grande in the Caué district. It is reachable by car from the capital São Tomé; the last kilometers are unpaved, so a four-wheel-drive vehicle is recommended.
What to expect
Birds can be well hidden - do not expect to see many species immediately. Take your time, sit quietly and wait; often birds appear on their own after a while.
