This Philippine island (344 km², and reaching 628 m; see map, p. 474) is a Secondary Area on account of one restricted-range species, Streak-breasted Bulbul Ixos siquijorensis, possibly numbering several thousand birds there (but classified as Endangered on account of its small and declining range); it also occurs on Romblon and Tablas (Secondary Area s095) and is extinct on Cebu (EBA 153). The widespread Rufous-lored Kingfisher Todirhamphus winchelli (Endangered) and Philippine Cockatoo Cacatua haematuropygia (Critical) are (or were) present on the island, but the kingfisher was very scarce and the cockatoo was down to one pair in 1991. Only four significant patches of forest remain, totalling less than 8 km², and, although all are in reserves, there are some signs of continuing degradation (Evans et al. 1993).
