Bar-winged Rail
(Gallirallus poecilopterus)

 
syn. Eulabeornis poecilopterus, Nesoclopeus poeciloptera, Nesoclopeus poecilopterus, Rallina poecilopterus, Rallus poecilopterus

 
distribution:

Fiji: Ovalau (?), Taveuni (?), Viti Levu

 
local name:

Saca (Fijian)

 
size: 33 - 35,5 cm

extinction date: last seen in 1890 (unconfirmed sighting in 1973)

 
The Bar-winged Rail is said to have been flightless, but as it seems to have been found on several islands, it must have been able to some sort of week flight.

Introduced feral cats and, above all, mongooses from India (Herpestes javanicus) are said to be the main reasons for the extinction of this species.

In the year 1973 the ornithologist D. T. Holyoak, who worked on intensive field studies on Fiji's main island Viti Levu, made the last sighting of a living Bar-winged Rail, but this sighting must be counted as unconfirmed because no irrefragable evidence exists.

~~~~~~~~~~~~~~~~~~~~~

In inserting this species into the genus Gallirallus I follow David W. Steadman's test results, according to which the two genera Gallirallus and Nesoclopeus cannot be seperated, neither osteological nor at the molecular level.
