Population justification: This species has no extant population.

Trend justification: This species is known to be extinct. The species persisted alongside humans and introduced predators for almost two centuries (Hume 2017). The primary cause of its eventual extinction is thought to be deforestation (Hume 2017). The last specimen was taken in 1826 (Hume 2017), and the last account of the species was given in 1832, which stated that the species still persisted in remote intact forest (Desjardins 1832). The species possibly survived until 1837 (Hume 2017).
