The Dwarf Olive Ibis, Bostrychia bocagei, is listed as ‘CRITICALLY ENDANGERED’ on the IUCN Red List of Threatened Species™. Found only on the island of São Tomé, it may now number fewer than 250 individuals.

The Dwarf Olive Ibis was known only from historical records and anecdotal evidence until its rediscovery in 1990. The clearance of much of São Tomé’s forest for sugar cane and cocoa plantations is thought to have had a serious effect on the species, and, although this has now largely ceased, forest is still being cleared for small farms. Predation by introduced mammals such as the Mona Monkey, African Civet and Weasel is also a problem. However, the most serious threat to the Dwarf Olive Ibis is currently hunting by humans.

Measures to protect the Dwarf Olive Ibis’s habitat have been proposed, but have yet to be implemented. Research, monitoring programmes and an awareness-raising campaign are underway, but enforced legal protection for the species, and effective protection of remaining forest, will be needed if the species is to survive.
