Guam Reed-Warbler (Acrocephalus luscinius)

Year Last Seen:

1969

Comments:

This species qualifies as Extinct. It is likely that the introduced Brown Tree Snake Boiga irregularis delivered the final blow to the species following significant habitat loss from wetland drainage and increased frequency in fires, potential impacts from pesticides and impacts of a variety of additional introduced species (Reichel et al. 1992, Kennerley and Pearson 2010).

Habitat:

Acrocephalus luscinius was almost exclusively found in freshwater wetland and wetland edge vegetation (Engbring et al. 1982, Reichel et al. 1992, USFWS 1998).

Causes:

The species was exterminated as a result of predation by the introduced Brown Tree Snake (Boiga irregularis). Several other factors are likely to have also contributed, including wetland destruction and drainage, pesticide-use, major fires and additional introduced species (Hume 2017).

Distribution:

This species is historically known from Guam (to USA).
