General characteristics

This Indonesian EBA includes Peleng and the Banggai Islands in Sulawesi Tengah province, and the Sula Islands (Taliabu, Mangole and Sanana) in western Maluku province. The islands are hilly, but the only significant area of land above 800

Restricted-range species

Until recently, the habitat requirements and conservation status of the restricted-range species were very poorly understood, but surveys of Taliabu (Davidson et al. 1995) and Peleng and the Banggai Islands (Indrawan et al. 1993) have added considerably to what is known. However, Indrawan et al. (1993) did not record Corvus unicolor (known by just two specimens believed to be from the island of Banggai; but see Collar et al. 1994) or Gymnocrex rosenbergii (known in this EBA by three specimens collected on Peleng). Tyto nigrobrunnea is only known from Taliabu by a single specimen collected in 1938 and a sighting in 1991 (Davidson et al. 1995).

All the other species are recorded from lowland forest, and some are also found in montane forest on Taliabu; one species, Rhipidura teysmanni, is much more common in montane than in lowland forest. Most of these birds can persist in secondary habitats, and some in all but the most degraded areas, including Coracina schistacea and C. sula (Davidson et al. 1995). Of the eight species confined to this EBA, four occur throughout, three are Sula Island endemics, and Corvus unicolor is known only from Banggai.

Sula Pitta Pitta dohertyi, which is confined to this EBA, was treated as a full species by Sibley and Monroe (1990, 1993), but is here considered to be a form of the more widespread Red-bellied Pitta P.

Threat and conservation

Most of Taliabu retains forest cover, but large-scale logging of lowland forest has taken place, and some areas have been clear-felled for industrial timber production. Most forest below 800
