White-winged Flufftail Sarothrura ayresi

Very rare, small rail of montane marshes. Extremely shy and elusive bird that is unlikely to be seen unless expressly looking for it. Dark on the back with a white belly. Male has a rufous hood. Both sexes show large white wing patches in flight. Known from a handful of shallow high-elevation marshes. May be migratory, though its habits are poorly understood. Call is a series of deep, hollow, two-part hoots.
