Kosrae crake
The Kosrae crake or Kusaie Island crake (''Porzana monasa''), sometimes also stated as Kittlitz's rail, is an extinct bird from the family Rallidae. It occurred on the island of Kosrae and perhaps on Ponape in the south-western Pacific which belong both to the Caroline Islands. Its preferred habitat were coastal swamps and marshland covered with taro plants (''Colocasia esculenta'').
== Description ==
It was discovered in 1827 by Heinrich von Kittlitz. Von Kittlitz described its plumage as general black with bluish gloss. The quills were more brownish. The chin and the middle of the throat were brown. The surface of its tail were brownish-black. The undertail coverts exhibit white spots. The inner wing coverts were brownish and were spotted with white. The outer edged of the first primary was dull brown. Eyes, legs and feet had a reddish hue. The bill was black. Its size was about 18 cm.
Controversial data exist according its ability to fly. X-ray measurements of the Carpometacarpii lead to the assumption that it was flightless. However its native name ''nay-tay-mai-not'' which means "the one who lands in the taro plot" might imply that the ability to fly was present.〔David Day (1981).
