We are thrilled to announce that the Dwarf Olive Ibis (Bostrychia bocagei) has been officially submitted as a candidate for the prestigious Indianapolis Zoo Uproar Conservation Challenge. This global initiative by the Indianapolis Zoo and the IUCN Species Survival Commission (SSC) shines a spotlight on lesser-known, highly vulnerable species to mobilize public action and direct vital funding toward their survival. We highly hope and anticipate that our unique ibis will be selected as one of the 64 final species to advance to the interactive head-to-head voting rounds!
About the Species and Extinction Threats
The Dwarf Olive Ibis (also known as the São Tomé Ibis) holds the title of the world’s smallest ibis and is classified as Critically Endangered on the IUCN Red List. Endemic entirely to the small island nation of São Tomé and Príncipe off the coast of Central Africa, its remaining population is precariously small, estimated at just a few hundred mature individuals surviving in highly restricted patches of primary lowland forest.
The species is facing an imminent risk of extinction due to severe overlapping threats:
-
- Habitat Loss & Fragmentation: Rapid agricultural expansion (such as oil palm plantations) and logging continue to clear the dense tropical forests that the ibis relies on for foraging and nesting.
- Severe Hunting Pressure: Exhibiting classic “island tameness,” these birds forage on the forest floor and display very little fear of humans, making them exceptionally vulnerable to local hunters.
- Invasive Predators: Introduced non-native mammalian predators heavily disrupt their breeding cycles by preying on nests high up in the tree canopies.
Active In Situ Conservation Work
Safeguarding the future of this fragile waterbird requires direct, on-the-ground action. Dedicated members of the IUCN SSC Stork, Ibis and Spoonbill Specialist Group are currently on the ground in São Tomé, executing crucial in situ conservation work. Our experts are actively studying the species’ distribution and breeding ecology while working in close partnership with local stakeholders to develop tailored management solutions, curb illegal hunting, and safeguard vital forest habitats from further destruction.
Being selected for the Uproar Conservation Challenge would provide a monumental boost to these ongoing field efforts. If selected for the main bracket, the Dwarf Olive Ibis stands a chance to secure up to $10,000 in direct conservation funding. Stay tuned for further updates on the selection process, and get ready to roar for the Dwarf Olive Ibis!
