Birdfinding.info ⇒ The last substantiated observation of Amaui was the collection of two specimens in Nu’uanu Valley on May 14, 1825. At that time, during the voyage of the HMS Blonde, it was reportedly common on Oahu, but it was not observed during the next major biological research expedition, which was in 1837, and there have been no reports thereafter.

Notes
Monotypic species. Traditionally considered conspecific with the Kama’o (M. myadestinus), Oloma’o (M. lanaiensis), and Oma’o (M. obscurus), collectively known as the Hawaiian Thrush (M. obscurus), but recognized as separate species since 1982. Sometimes also considered conspecific with just the Oloma’o, but genetic analyses of relatedness reportedly support treatment as a separate species.
IUCN Red List Status: Extinct.
