• Also found on Aiwa was a single bone of a " Porzana " rail.
• Due to the peculiar shape of the carpometacarpus Olson named this species " Porzana astrictocarpus ".
• ""'Porzana " "'is a disputed genus of birds in the crake and rail Venetian terms for small rails.
• Unlike other " Porzana " crakes, this species has strong sexual dimorphism : Adult males have mainly brown upperparts and blue-grey face and underparts.
• Among them are the Kosrae crake ( " Porzana monasa " ) and Kosrae starling ( " Aplonis corvina " ) which are known only from his specimens.
• Olson proceeded on the assumption that the Saint Helena crake was a derivative of the Baillon's crake ( " Porzana pusilla " ), which is widespread in Europe and Africa.
• The "'sora "'( " Porzana carolina " ) is a small waterbird of the family Rallidae, sometimes also referred to as the sora rail or sora crake.
• The genus name " Porzana " is derived from Venetian terms for small rails, and Carolina refers to the Carolina Colony . " Sora " is probably taken from a Native American language.
• Regardless, it seems to be reasonably close to the striped crake, formerly also in " Poliolimnas " ( or " Porzana " ) but subsequently separated as " Aenigmatolimnas ".
• While it does not seem to be part of " Porzana " proper but belong to the " Coturnicops "-" Laterallus " clade, its precise relationships are still insufficiently resolved.
• The "'Saint Helena crake "'( " Porzana astrictocarpus " ) is an extinct bird species from the island of Saint Helena in the rails which survived there until the early 16th century.
• Birds described from subfossil remains that became extinct as a consequence of human settlement of the island and the introduction of exotic mammals include the Mangaia rail ( " Gallirallus ripleyi " ) and the Mangaia crake ( " Porzana rua " ).
• However, molecular phylogenetic analyses have confirmed the suspicion, raised in the late 20th century in the first cladistic studies of morphology, that the " genus " " Porzana " is rather an evolutionary grade, consisting of an assemblage of unrelated plesiomorphic rails.
• The "'Great Oahu crake "'or "'Great Oahu rail "'( " Porzana ralphorum " ) is an extinct bird species rails that had survived on the island until the arrival of people in 200 C . E.
• The Ash-throated Crake, which was only tentatively placed in " Porzana ", has been united with the two former species of " Neocrex " in " Mustelirallus "; they are almost certainly closely related to " Pardirallus ".
• This was first described as " Ortygometra egregria " by Wilhelm Peters in 1854 from a specimen obtained in Mozambique, and has variously been placed in the genus " Porzana " or its own genus, " Crecopsis ", but is now more usually placed in " Crex ".
• The endangered Australasian bittern ( " Botaurus poiciloptilus " ) is found in the wetland with other endangered birds such as the banded rail ( " Rallus philipensis assimillis " ), marsh crake ( " Porzana pusilla affinis " ) and the North Island fernbird ( " Bowdleria punctata vealeae " ).
• Finally, there is " Porzana " proper, a group of a few fairly large species which seems close to the last common ancestor of coots and moorhens; the Spot-flanked Gallinule, presently placed in " Gallinula " or separated in a monotypic " Porphyriops ", may be a particularly close relative.
• On the Big Island, a smaller species of " Porzana " is now known from subfossil bones found on the southwestern slope of Mauna Kea, but this bird was only the size of a Laysan crake; it may have been the bird named " iao " or " iao ", which would place its extinction at a relatively recent date.
• Despite its visual similarities, it probably does not belong to the genus " Porzana "; like the Yellow-breasted crake, which was variously placed in " Hapalocrex, Micropygia, Poliolimnas " or " Porzana ", it seems to form a badly-resolved complex with the mainly Neotropical crakes of genera " Anurolimnas, Coturnicops " and " Laterallus ".
