Range Description

Zosterops albogularis is endemic to Norfolk Island (to Australia). It was reported as "very plentiful" by Hull (1909) and 12 specimens were taken in one week in 1926 by Correia. However, the population is thought to have fallen below 50 individuals by 1962 (Mees 1969), and by the 1970s it had become confined to weed-free indigenous forest in and around the Norfolk Island National Park. Although formal searches have failed to find any in the last three decades, there have been scattered sightings throughout this period (Schodde et al. 1983), including one in 1987, two in 1991, four in 1994 and one in 2000. Since then a number of unconfirmed reports have been logged from the Norfolk Island National Park, most recently in 2006 (B. Watson in litt. 2006, G. Dutson in litt. 2009, 2010). The remaining population, if any exists, is likely to be very small; a comprehensive three-week survey in November 2009 based on 353 point counts failed to find the species and concluded there was a 90% chance that it was functionally extinct (G. Dutson in litt. 2009, 2010, Dutson 2013).
