Population justification: No extant population remains.
Trend justification: There has only been one record of the species in life, from 1672-73 (Dubois 1674). Nothing is known about the cause of its extinction, but it Dubois' (1674) account suggest it was hunted for consumption, and it was likely impacted by introduced predators, and went extinction sometime in the 1700s (Hume 2017).
