Democratic Republic of São Tomé and Príncipe

São Tomé and Príncipe is an island country in the Gulf of Guinea, the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands of São Tomé and Príncipe, about 150 km (93.21 mi) apart and about 250 and 225 km (155 and 140 mi) off the northwestern coast of Gabon. With a population of c. 235,000, and a land area of 964 km2 São Tomé and Príncipe is the second-smallest and second-least populous African sovereign state after Seychelles.

The islands are part of the Cameroon volcanic mountain line, which also includes the islands of Annobón to the southwest, Bioko to the northeast (both part of Equatorial Guinea), and Mount Cameroon on the coast of Gulf of Guinea. São Tomé is 50km long and 30km wide and the more mountainous of the two islands. Its peaks reach 6,640 feet at Pico de São Tomé. Príncipe is about 30km long and 6km wide. Its peaks reach 3,110 feet at Pico de Príncipe. Swift streams radiating down the mountains through lush forest and cropland to the sea cross both islands. The Equator lies immediately south of São Tomé Island, passing through the islet Ilhéu das Rolas.

The climate of São Tomé and Príncipe is essentially conditioned by its geographic location, subject to the seasonal translation of low equatorial pressures, the monsoon winds from the south and the warm Guinea Current. At sea level, the climate is tropical – hot and humid with average yearly temperatures of about 26 °C and little daily variation. The temperature rarely rises beyond 32 °C. At the interior’s higher elevations, the average yearly temperature is 20 °C and nights are generally cool. Annual rainfall varies from 7,000 mm in the highland cloud forests to 800 mm in the northern lowlands. The rainy season is from October to May.

The country’s territory is part of the São Tomé, Príncipe, and Annobón moist lowland forests ecoregion. It does not have a large number of native mammals (although the São Tomé shrew and several bat species are endemic). However, the islands are home to a larger number of endemic birds and plants, including the world’s smallest ibis and the world’s largest sunbird. The islands are also an important marine turtle-nesting site, including the Hawksbill Turtles Eretmochelys imbricata.

Birding Sāo Tomé & Principe

The Gulf of Guinea islands: Nestling in the armpit of Africa the four islands of Bioko, Príncipe, São Tomé and Annobón have been virtually ignored by birders and until very recently, have been the preserve of expeditions and the more ambitious bird-tour companies. This is surprising given that the islands offer some of Africa’s most spectacular scenery and, although you will not see hundreds of species, the number of endemics is truly impressive – 28 on São Tomé and Príncipe alone. These range from the incredible Giant Sunbird through to the São Tomé Short-tail, a bird unlike any other with its own genus. Several species, including the Dwarf Olive Ibis, São Tomé Fiscal Shrike and São Tomé Grosbeak have been seen by very few living birders! However, with a bit of adventure these species may be seen in the remote southwestern forests of São Tomé. Coupled with the birds the people are amongst the friendliest in Africa, the scenery is spectacular and the many beaches are wonderful. It is an ideal place to spend some time.

Geography and Biodiversity: These volcanic islands form a line of extinct volcanoes, starting with Annobón in the southwest and reaching up northeastwards to Mount Cameroon and beyond. The two middle islands in the chain, São Tomé and Príncipe, form the Democratic Republic of São Tomé and Príncipe. Bioko, the biggest island and the closest to mainland, and Annobón, the smallest and more inaccessible, are part of Equatorial Guinea.

Bioko is part of the continental shelf and was only isolated from the mainland 11,000 years ago. It has, therefore, a rich fauna and flora of continental origin, but low levels of bird endemism although for it size it has one of the highest diversity of primates in the world. Príncipe, São Tomé and Annobón are oceanic islands and have never been connected to mainland or to each other. Their fauna and flora having evolved independently is characterised by high levels of endemism. Even the extremely small Annobón (9×3 km) has two endemic land birds, the Annobón White-eye and the Annobón Paradise Flycatcher, shares the endemic Bronze-naped Pigeon with São Tomé and Príncipe, and hosts a sub-species of the African Scops Owl. São Tomé and Príncipe are undoubtedly the stars of the pack, with more than twice the number of endemic birds that could be predicted by area alone.

Access: All the islands can be visited, although access to Annobón is really only possible from mainland Equatorial Guinea or by private yacht charter from São Tomé. Access to São Tomé is via TAP Air Portugal flights, which depart from Lisbon, or with Air Gabon, which departs from Libreville. Libreville is connected to most African cities and to Europe, via Paris. Access to Príncipe is by air via São Tomé. Apart from two main local languages, Portuguese is widely spoken and French is the most spoken second language. English is spoken at hotels and by some guides.

Birding Sites: Most of the endemics on São Tomé and Príncipe are easy to see and can be seen around the main towns. (See Top Sites below for details of other sites).

When to visit: All the endemics in São Tomé and Príncipe can be seen at any time of year. However, access to the southwestern forests in São Tomé will be difficult in the rainy season. The periods June to August and December-January are the best as they are the two drier periods.

Accommodation:  Accommodation in São Tomé is varied but not necessarily cheap. It ranges from the up-market Marlin Beach Hotel and the Hotel Miramar to small pensions. In between there are several small, well-equipped establishments that cost half as much as the upmarket hotels including breakfast. For long stays, renting a place can be more economic. Accommodation in Príncipe is limited to the up-market Bom Bom Island Resort and a couple of pensions in town. Pensão Romar is recommended. It has a very special atmosphere, and friendly service. Its balcony bewitches most of those that have passed by. To top it all, Zôzô is an excellent cook (ask her for local dishes which she excels at).

Hazards: Malaria is the main health concern in the islands. Follow the prophylaxis regime recommended by your doctor and take care to avoid mosquito bites especially at dusk. The use of repellent and a mosquito net at night is strongly recommended. The golden rule is to consider any difference in your physical well-being as a possible symptom of malaria, and go and get it checked it in a clinic or hospital. The only other major hazard in the forest is black cobras. Initially introduced to reduce rat populations in the plantations, these snakes have spread into the forest. They generally get out of your way and there have been no reported cases of birders having problems. However, take care crossing fallen logs and dry streambeds where they like to bask in the early morning. Contact your doctor if you require advice on snakebites. As in any tropical area care should be taken with water consumption. When in towns drink bottled water or use sterilising tablets or drops of iodine to be safe. Water direct from rivers in the southwest is probably safe.

Birding and which field guides to use: Despite being virtually unknown by birders, RDSTP and Bioko have their own field guides. The Christy & Clarke guide is the most up to date and the Sargeant bird-finding guide, although fairly old, still holds good. Abbé René de Naurois volumes cover both islands and are a summary of his 20+ years research on the island’s birds.

Further information, NGOs & Links: By far and away the best resource for those interested in the different groups of plants and animals is the Gulf of Guinea Conservation Group. Here you can find information about the different islands, species lists and a whole host of information about living and working in the Gulf of Guinea. This web site is maintained from São Tomé and there is also an informal e-mail discussion list that can be joined. The travel agency Mistral Voyages mvoyages@cstome.net with an office in São Tomé, can help you organise your trip.

  • Príncipe Ilhas Tinhosas

    Satellite View
    The seabird islets 20 km south of Príncipe, the Ilhas Tinhosas, are well worth a visit and boats can be hired through the Bom Bom Island resort. Sooty Terns, Black and Brown Noddies and Brown Boobies breed in many thousands in these tiny rocks. Do not land on the islets: besides being extremely dangerous it causes great disturbance to the birds.
  • Príncipe Southern Forests

    Satellite View
    On Príncipe, all the endemics (6 in all) can be seen on roads around the town, although a visit to the southern forests is recommended to see the Príncipe Thrush - a sub-species of the São Tomé Thrush that may be split in the future. The southern forests are also the strongholds of the African Grey Parrot breeding population, and its shores are the best place to see the Príncipe Seed-eater. Most of Príncipe can be explored on day-walks, but spending one night in the southern coast, bordering the rainforest is recommended: a small owl described by local people has still to be found by outsiders, and it is a good bet to try to spot the seldom seen Príncipe Olive Ibis…
  • São Tomé peak

    Satellite View
    For the pure scenery pleasure a two-day walk to the São Tomé peak (2,024 m); crossing different forest types, is a must. For the more intrepid, a visit to the southwestern forests is essential to see species such as the Dwarf Olive Ibis, the fiscal shrike, the short-tail and the grosbeak. Here, where it rains almost everyday even in the dry season, it will probably be necessary to spend 1-2 nights camping in the forest to ensure that all the endemics are seen.

    The natural park was established in 2006 and is the country's only protected area at the national level. The park is known internationally amongst conservationists for its biologically rich dense virgin rainforests. It is also characterized by a wide range of biotopes, from lowland and mountain forests, to mangroves and savanna area, which contribute to its unique ecosystem. The park includes virgin Atlantic high altitude rainforest and secondary rainforest (known to locals as capoeira) which contains abandoned plantations. In 1988, scientists classified the forests of São Tomé and Príncipe as the second most important in terms of biological interest out of 75 forests of Africa; most of the species found in the islands are found in the national park. Birds include the São Toméan grosbeak (Crithagra concolor), São Toméan ibis (Bostrychia bocagei), São Toméan shorttail (Amaurocichlia bocagei), the Giant sunbird (Dreptes thomensis), São Tomé fiscal (Lanius newtoni), São Tomé oriole (Oriolus crassirostris) and São Tomé thrush (Turdus olivaceofuscus).
