Tahiti ‘Goose’ (Porphyrio sp.)

There is a nearly unknown contemporaneous account from the 18th century by James Morrison, boatswain’s mate on board on the infamous ‘Bounty’ who mentiones a enigmatic bird.:

“… the mountains produce birds of different kinds unknown to us, among which are a large bird nearly the size of a goose, which is good food;  they are never observed near the sea nor in the low lands.“

This mysterious, nearly goose-sized bird very likely was a rail, perhaps from the genus Porphyrio, which is known to have produced a radiation of numerous species all over Oceania.
