Characteristics A separate window opensReferences

These are the waters in the vicinity of the mouths of the Mu and Saru rivers. These river mouths are important habitats for birds, with relatively large numbers of species and individual specimens during the migration seasons of spring and fall. Species recorded in the river-mouth tidal mud flats include the black-winged stilt, Far Eastern curlew, and Latham's snipe (Ministry of the Environment, 2001). Both these rivers also see Spirinchus lanceolatus migrating upstream to spawn.
