Range Description

Otus beccarii is endemic to the twin islands of Biak-Supiori in Geelvink Bay, Papua (formerly Irian Jaya), Indonesia (Mayr and Meyer de Schauensee 1939, Marshall 1978, Konig et al. 1999, Marks et al. 1999). Its status is uncertain, as it is a nocturnal species with poorly-known calls and only recently considered to be a separate species. A survey of the island in 1973 found only one pair (S. D. Ripley in litt. to Clark and Mikkola 1989), and it was not recorded during three visits to Biak in the 1990s (Gibbs 1993, Poulsen and Frolander 1994, Eastwood 1996b). One was heard in and around Biak-Utara Reserve in 1997 (B. Beehler and S. van Balen in litt. 2000), and two were heard one morning in 1995 (M. Van Beirs in litt. 2000). However, more recently, the species has been encountered regularly in remnant forest patches in southern Biak (K. D. Bishop in litt. 2012). Subsequently, it has been suggested that this species is widespread in forested habitats around Biak and Supiori (B. Beehler in litt. 2012, G. Dutson in litt. 2013).
