Status
The São Tomé fiscal is a very rare bird. There were records of sightings in 1888 and again in 1928. Another individual was sighted in 1990 near the source of the Rio Xufexufe, and a number of birds have been spotted since then. All sightings have been in primary forest with rocky areas but little undergrowth, sometimes on low ridges or beside watercourses, and always below . This type of habitat is decreasing as forests are cut to create coffee and cocoa plantations, and the building of new hydropower plants are another possible threat, even though it is a protected area (Parque Natural Obô de São Tomé
