Tongatapu rail
The Tongatapu rail is an extinct species of bird in the family Rallidae. It was apparently native to the island of Tongatapu in the Kingdom of Tonga, in Polynesia in the south-west Pacific Ocean. It is known only from brief descriptions of a specimen, now lost, collected from Tongatapu in 1777 in the course of James Cook's third voyage to the Pacific, and from a contemporary illustration by Georg Forster.
