    Scolopaci

    Just re-checked the complicated circumstances by which names from Cuvier, 1800 became available. Seems I've overlooked an important detail. Well then, Calidris is from Anonymous [=Merrem], 1804.

    Scolopaci

    Calidris was first introduced in Cuvier, 1800, together with Psittacula, Regulus, Erithacus, Vidua and Chloris. Calidris and Vidua are usually attributed to later sources, but I have no idea why. If Calidris had to be taken from Anonymous [=Merrem], 1804, precedence between this name and...

    Scientific name of Common Bush Tanager

    Edward Dickinson sent me an email, saying Email to Van Remsen already sent!

    Scientific name of Common Bush Tanager

    Hi, does anybody know why the name of the Common Bush Tanager is Chlorospingus ophthalmicus (Du Bus de Gisignies, 1847) and not Chlorospingus flavopectus (Lafresnaye, 1840), despite the latter name having 7 years priority? Is it conceivable that this has escaped the attention of all previous...

    Corvus pumilis vs. Corvus pumilus

    Or an incorrect subsequent spelling, which is not the same, technically!

    Grafisia

    Quite unlikely. As said by others before, in "H. Graf", Graf is a surname. In "Johann Graf von Borcke" it is a title of nobility, placed after the first name, as usual in Germany since 1919.

    'Menorcan Shearwater'

    Names for PSC or ESC species will be the same as for subspecies, just becoming binominals instead of trinominals. No chaos at all! Rainer

    'Menorcan Shearwater'

    I sincerely doubt that. BirdLife will always have to draw a line between populations they think should be evaluated, and those which should not. Currently this line is the distinction between species and subspecies. Sometimes taxa flip from one side of the line to the other or back, but there...

    'Menorcan Shearwater'

    Well, fish taxonomists virtually don't use subspecies at all! There are at most 300 currently recognized subspecies of fishes compared to more than 30,000 species (don't have the source at hand, will look for it). And their number is declining... Subspecies in fishes now seem to be confined to a...

    IUCN Red List 2012

    It's not the purpose of these lists to literally predict extinctions, but to assess the extinction risks for those species, in order to develop effective conservation measures. Sort of a self-inhibiting prophecy, if it works! This effect must be taken into consideration.

    DO-G 144th Annual Meeting

    "We are checking if the splits within Carpodacus, as proposed by Rasmussen (2005), are justified..." but they don't tell us their results :(. However, they confirm the split of C. formosanus from C. vinaceus by Wu et al. (2011).

    Undescribed

    The holotype must be designated explicitly (article 16.4.1), i.e. a statement like "we designate the photographed specimen as holotype" would be required. So that door is closed, too!

    Anatidae

    When looking at the images, I must say I don't buy the results of the Fulton et al. study. Surely the morphological differences must have a genetical basis. I'd rather think of some kind of introgression. Maybe a small founder population of flyers was genetically swamped by resident non-flyers...

    All right, I missed that. Stotz's vote does not appear on the discussion page. Rainer.
