The only coot in the Hawaiian Islands. Similar in appearance to American Coot, but the frontal shield above the bill is larger and more bulbous. Shield may be white or dark reddish-brown. Distinguished from Common Gallinule by white frontal shield, gray feet and legs, and lobed toes. Occurs in wetlands, lakes, ponds, marshes, canals, and golf courses. Often grazes in grassy areas adjacent to wetlands.
