    Purple Swamphen (Porphyrio porphyrio) is larger with a bright purple front and all red bill and shield. 

    Eurasian Coot (Fulica atra) is recognised by its snowy white bill and forehead shield.

    Black-tailed Native-hen (Tribonyx ventralis) is a large, stout, dark, fleet-footed rail with an erect narrow black tail which is held folded. The bird is mainly brownish-grey, with white spots on the flanks. The bill and frontal shield is green, with an orange-red lower mandible ('jaw'). Legs and feet are bright pink. The eye is bright yellow. They are seen in pairs, parties and sometimes large groups.

    Tasmanian Native Hen (Tribonyx mortierii)is a large, heavy bodied, flightless bird found only in Tasmania. It is similar in shape to the Black-tailed Native-hen Tribonyx ventralia but is larger. The Tasmanian Native-hen has a large yellow bill, a red eye, brown head, back and wings and is slate grey on its underparts. The contrasting black tail is long and narrow and is flattened along the mid-line of the bird . The legs are powerful and grey in colour. Juvenile birds are similar to adults but duller.

    Bush-hen (Amaurornis moluccana) belongs to the same family as crakes and rails. It has brown back and wings and grey throat and chest with rusty tan coloured rear and under the tail. The bill and legs are greenish. It is not often seen as it spends most of the time in dense vegetation near water. It is a good swimmer and also wades in shallow water. 

    Spotless Crake (Porzana tabuensis) is a cryptic water bird found in the Philippines, SW Polynesia, Australia, and New Zealand.
