    Maybe better to state that it is beyond my level of expertise. Niels

    Turdidae

    The below snip is from a 2007 paper by Voelker et al. according to which it could be done. Whether their statements are correct is beyond me. Niels

    Turdidae

    Interesting that the recommendation is "no" because of lack of published data Niels

    Turdidae

    I am not sure I follow you here. How would reverting to an older type species be upsetting as long as both are members of the genus as currently defined? It would become upsetting at the moment that a split moved the two apart but not before. Niels

    If you take the above maps and only show December, both forms are seen in CR during that month. Whether those determinations are correctly identified observations is unknown to me. Niels

    I believe I have a couple of photos which eventually needs to be looked at in more detail ... Niels

    Both forms are defined as ebird groups. Here are the maps: https://ebird.org/map/swathr1?neg=true&env.minX=&env.minY=&env.maxX=&env.maxY=&zh=false&gp=false&ev=Z&mr=1-12&bmo=1&emo=12&yr=all&byr=1900&eyr=2019...

    I probably would have gone with Pan-Tepui instead of the single word version (Pantepui). I realize that sounds weird coming from someone Danish; we are known for combining words! Niels

    Turdidae

    But the remarks state that they went with Pantepui over Tepui as common name ... Niels

    Turdidae

    I have especially looked at discussions for the Americas. Where 10 years ago you might get away with using only mitochondrial DNA as indicator of species status, currently you will have to include nuclear areas before the evidence will be taken seriously. Niels

    Turdidae

    So too strong conclusions from a relatively weak dataset? You would never get a species split based on only mitochondrial DNA, so why should you get lumping from only that? Niels
