Water rail
The nest is made from whatever wetland vegetation is available and built mostly by the male, usually in a single day. It is raised or more above the level of the marsh, and is sometimes constructed on clumps of roots, tree stumps or similar support. It may be built up higher if the marsh waters start to rise. The nest is across and about high. It is well hidden and approached by narrow tracks.
