David W. Steadman, Two new species of rails (Aves: Rallidae) from Mangaia, southern Cook Islands Pacific Science 40 (1986): 38-54 Full text article here: scholarspace.manoa.hawaii.edu/bitstream/10125/1002/1/v40-27-43.pdf There is something intringuing data cited on the article: "Only one of the three species of rails known from Mangaia survives there today, and this very likely is Porzana tabuensis, although no modern specimens exist to document its occurrence. According to the Mangaians, a small, black rail exists on their island. This elusive bird is known as the "mo'o mo'o." Many Mangaians told me ofseeing or hearing the "mo'o mo'o " on rare occasions in the taro swamps on the inner side of the makatea. These persons generally said that the bird has become rarer during their own lifetimes. As noted in Steadman (1985), the capture of a modern specimen of"mo'o mo'o" is a goal of future fieldwork on Mangaia. It would seem at first that the "mo' o mo'o" will prove to be P. tabuensis, particularly because some Mangaians claim that it can fly, although weakly and not for long distances, and because one would presume that a volant or bare ly volant species would persist longer than a flightless species such as Porzana rua. Nevertheless, when confronted with Plate 9 of duPont (1976), in which both P. tabuensis and P. atra are illustrated in color, the Mangaians invariably pointed to P. atra as being their "mo' o mo'o ," noting the totally black body and the bright red iris and tarsus. Until a specimen is procured, it is uncertain whether Mangaia's rare but surviving "mo'o mo'o" might be P. rua rather than P. tabuensis." |
