Abstract

The islands of Sangihe, Siau and Talaud were visited between 24 August and 31 October 1995 and a total of 126 species recorded. This paper provides details of all species recorded, including those new to the islands, additional information is provided on the five endemic species: Eos histrio, Loriculus catamene. Halcyon enigma, Eutrichomyias rowleyi and Aethopyga duyvenhodei. Further details are provided of records made between 1986 and 1995 during visits to the islands by four individual birdwatchers. Four of the endemic species were shown to be more common than previously thought, whilst details of the third record of Eutrichomyias rowleyi are presented. The conservation status of the islands is discussed and recommendations made for future research.

Abstract

The Satanic Nightjar Eurostopodus diabolicus a little-known, putatively threatened species endemic to Sulawesi, Indonesia was recently observed in two protected areas in North Sulawesi. Presently classified as Vulnerable to extinction, these new records suggest a more widespread geographical distribution and greater tolerance of disturbed habitats than was previously thought. Consequently, we recommend that this species be downgraded to Near Threatened. Descriptions of plumage characters (which differ from the type specimen in some respects), nesting, and behaviour are presented. Morphological and ecological evidence suggests E. diabolicus is most closely related to the Archbold's Nightjar E. archboldi and Papuan Nightjar E. papuensis, both endemic to New Guinea.

Abstract

Panua Nature Reserve is the second largest terrestrial conservation area in North Sulawesi, located on the south coast of Sulawesi's north peninsula. We conducted surveys of the reserve between February and June 2000, including 241 km of line transect censuses, primarily in the dominant lowland evergreen rainforest. A total of 124 bird species were recorded, including 48 Sulawesi endemics, and l3 species (all but two endemic) that are considered by most authorities as Threatened or Near Threatened. In this paper we describe the habitats of the reserve and summarize observations of all l3 threatened species, as well as six other species for which our surveys clarify distribution or status within Sulawesi.
