From the Reise der österreichischen Fregatte Novara [...] Zoologischer Theil, A. Pelzeln, "Vögel":

"A specimen captured by B. Wullerstorf on 2 January in Manukai Forest at Whau Road 13 miles west of Auckland. Iris blue-red, beak shiny black, legs dark lead coloured bluish, markings of same brownish. Total length 9/", flight distance 15". This bird is not uncommon in primeval forests and very often emits its deep whistle tuitui, from which it got its name from the natives. The song is similar to that of our starlings2 (p. 57)
