Population justification
This species is extinct.
Zosterops conspicillatus was formerly found on Guam, last recorded in 1983 and is now extinct (del Hoyo et al. 2008). The introduction of the Brown Tree Snake Boiga irregularis is the most likely cause (van Balen 2016, Hume 2017).
Similar to the extant Z. saypani the species is thought to have been found in a wide range of habitats from native limestone forest to scrubby secondary growth of disturbed habitats and even urban areas.
The species' demise is thought to be due to the invasive Brown Tree Snake Boiga irregularis (van Balen 2016). In 1976 its habitat was also devastated by super-typhoon Pamela (Hume 2017).
