チャバラクイナ Amaurolimnas concolor

Larger than most crakes. Found in wet forests instead of marshes. Very difficult to see as it creeps through dense understory. Far more easily heard: a series of upslurred whistled notes. Look for a brown bird with richer rufous underparts, a dull greenish-yellowish bill, and reddish legs. Favors dense wet forest or thickets, often but not always near a swamp or stream.
