Eua Thrush (Turdus sp.)
The thrushes that once inhabited the island of ‘Eua, Tonga were either identical with those from the neighboring island of Tongatapu, or, more likely, were a distinct subspecies or species.
The taxon, whatever it may have been, is known only from subfossil remains, and died out soon after the arrival oft he first Polynesain settlers. [1]
