Aguijan Reed-Warbler (Acrocephalus nijoi)

Year Last Seen:

1995

Comments:

There have been no records of the species since the mid-1990s despite extensive surveys in 2000, 2001, 2008 and 2009, its disappearance likely primarily due to large-scale vegetation clearance. It is therefore classified as Extinct.

Habitat:

It inhabited formerly disturbed areas vegetated by groves of trees and thickets (Engbring et al. 1982, Reichel et al. 1992, USFWS 1998).

Causes:

Habitat destruction as a result of intensive farming is likely responsible for this species' disappearance (Reichel et al. 1992). Goats (Capra hircus) introduced in the 1950s may have also been a contributing factor (Hume 2017).

Distribution:

This species is historically known only from Aguijan in the Northern Mariana Islands (to USA).
