Turdus sp. ‘Tongatapu’

Tongatapu Thrush (Turdus sp.)

This thrush from the island of Tongatapu, the largest island in the island kingdom of Tonga, is known only by subfossil remains. [1]

Most of the thrush populations that formerly were assigned to as subspecies of the so called ‚Island Thrush‘ (Turdus poliocephalus Latham) are now more or less generally accepted as being distinct species, thus I’d like to consider all of the Polynesian thrushes as being resp. having been distinct species restricted to single islands each.
