Information about the Bird Sao Tome Ibis

The So Tom ibis (Bostrychia bocagei), also known as the dwarf olive ibis, is a critically endangered bird that is endemic to So Tom off the western coast of Central Africa. Once thought to be a subspecies of the larger olive ibis, it is now classified as a distinct species.

The So Tom ibis's measurements include: wings 248mm; bill 73mm; tarsus 52mm; and tail 95mm. The head is dull olive with black surrounding the eyes and base of the bill. The wing-coverts and mantle are slightly bronzed.
It is silent most of the time, but when disturbed it gives various coughed grunts, and a harsh honking when going to roost. Its call could also be described as a stressed kh-gh kh-gh.
It is found in primary forest below 450m altitude. It forages for food on the forest floor with sparse undergrowth, especially where the ground has been disturbed by wild pigs, and in swampy areas bordering watercourses.
The extremely small population of So Tom ibises contains only around 50 to 249 individuals. Due to this, it is listed as Critically Endangered on the IUCN Red List.
Introduced species could negatively affect the numbers of these birds. Habitat loss is another threat, and road development has increased access to previously remote areas. They also may be hunted. A national park and the protection of threatened species in So Tom have been proposed, but currently the forests are unprotected.
