Pale-vented Bush-hen Amaurornis moluccana

Very secretive medium-sized rail that inhabits dense vegetation around wetland habitats in northern and northeastern Australia. Rarely seen away from cover. Dull gray-blue body, brown wings and tail, with reddish-brown undertail, yellow-green bill with small shield, and long yellow legs. Gives a variety of calls, usually a loud, repeated, squawky "wark-wark-wark" or an agitated "wark-woop, wark-woop, wark-woop."
