Introduction
Sao Tome Ibis
- Francisco Newton, a Portuguese collector
- Critically Endangered species
Habitat
(Western Africa)
Reproduction
It chooses to nest between 8m and 16m up in the trees in the forests. The nests were composed primarily of twigs and other biomass material, with leaves and feathers lining the inside. The nests had diameters of between 330 and 370 mm x 260–360 mm
Alimentation
Ibis Food (no perticular)
- great variety of prey
- terrestial or aquatique
- invertebrates, small vertebrates
- warms, insects
- fish, lezards
+couldn't find specific information for the dwarf ibis
Threats
A neighboring subspecies of the São Tomé ibis on the island of Príncipe became extinct in the last century, indicating that small habitats like São Tomé make ibises more vulnerable to threats and extinction.The São Tomé ibis is facing problems that are both environmental and anthropogenic that contribute to its status as critically endangered.
The extremely small population of São Tomé ibises contains between 50 and 249 individuals.
Due to this, it is listed as Critically Endangered on the IUCN Red List.

Way of living
- silent (exept when disturbed)
- high nests to avoid predators
- no running water to protect eggs
(rats, snakes, monkeys)

Human Threat
- ~75% native flora loss since 1500s
- São Tomé dwarf ibis endangerment
- Anthropogenic pressures: habitat loss, urbanization, overhunting
- Infrastructure development: roads, railways, dams
- Major deforestation driver: oil-palm concessions
- Additional plantations: cacao, coffee, quinine, cinnamon
- Population growth and rising resource demand
- Reduced habitat availability and breeding range
- High vulnerability due to ground-foraging behavior and island tameness
Humanitary Help
- under protection
- work with tourists and hunters, less studies, awareness
- 100 years - active for 40
- Bom Sucesso Botanical Garden/Obo Natural Park
- ECOFAC
- Species Conservation Funds
- International Organisation
- Fauna and Flora
Future Challenges
- Growing conservation efforts on São Tomé
- No dwarf ibis–specific protection
- Focus on general biodiversity and flora
- Overhunting and tourism pressure
- Cooperation with hunters and tourism sector
- Public awareness and outreach
- Extraction-focused local attitudes
- Need for cultural shift toward conservation
