Hosszúlábú álfakusz
    Xenicus longipes (Gmelin, 1789)

    A hosszúlábú álfakusz (Xenicus longipes (Gmelin, 1789)) talán még ma is él a zord, tenger szabdalta Fiordland vidékén, bár ezt az egykor nagy elterjedésű fajt ma általában kipusztultnak tekintik. Három alfaja élt: a Xenicus longipes longipes a Déli-szigeten, a Xenicus longipes stokesi az Északi-szigeten és a Xenicus longipes variabilis a Stewart-szigeten. Az Északi-szigeten élt alfaja mindig is ritkának számított. Múzeumi gyűjteményben is csupán a típuspéldányai találhatók, melyekről a fajt eredetileg leírták. Utoljára az 1950-es években került szem elé. Ugyanebben az időben tűnt el a Stewart-szigetről a Xenicus longipes variabilis is, de ez az alfaj még egy ideig tartotta magát a közeli Big South Cape szigeten. A behurcolt patkányok pecsételték meg sorsát.

    The Bush Wren was first collected by the naturalist on board Captain Cook's second voyage to the area in 1773. This was the first time that the bird was seen by Europeans.

    Like many other birds of New Zealand, the Bush Wren usually nested on, or just above, ground level. This meant that it was exposed to the attacks of the cats, rats, pigs and stoats introduced by the Europeans.

    The North Island race was the first to disappear. Described in 1850, it only lived in a small area of the South-east of the island. By 1900, the race was extinct.

    The next to go was the Stewart's Island race. Although it was safe until 1963, the accidental introduction of rats onto the island at around this time spelled disaster. Unlike other races, these birds nested in the burrows of petrels on the island and its islets. This made them easy prey for the rats, which quickly wiped out the population. By 1965, the Stewart Island Bush Wren no longer existed.

    Last of the group to disappear was the South Island Bush Wren. This race managed to survive until the mid 1970s. It has been suggested that the South Island Bush Wren may still occur in the forests of Fiordland, although this suggestion has not been confirmed.
