サトイモ
The Kosrae crake or Kusaie Island crake ("Zapornia 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").
