    Time calibration and Linnean ranks in birds

    I've also seen 'spangled plovers'.

    Antpitta

    Also, is the 'Dancing' Antpitta from Cali still undescribed? (Paper "coming soon" 5 years ago) https://www.birdguides.com/news/antpitta-discovered-in-colombia-is-new-to-science/#:~:text=The%20bird%20does%20not%20yet,dance')%20in%20this%20fashion.

    Phylogeny of birds

    No, they don't name it (or if they do, I can't find the info). Are there any reasons we should favour this phylogeny over previous ones? Some of the 'loose ends' seem to be conveniently tied up - e.g. grebes/flamingos, pigeons/cuckoos, hoatzin - and I'd like to trust that ...but the...

    Corvoidea

    Agree we need more data before anything official happens but I enjoy the speculation :) Plumage-wise, if we ignore chrysoptera, there is a pattern which also makes biogeographical sense. Western black-capped group Eastern white-headed group Northern (Papuan/Queensland) striated group...

    Corvoidea

    It would be good to have Neosittidae with Neositta in it, that's for sure - but only c. 5 million years of separation. Extra support for paraphyly of D. chrysoptera more noteworthy for me - and ancient divergence within Alaeadryas, Cinclosoma ajax, Pachycephala soror & Melanorectes. Interesting...

    Nectariniidae

    How is it accessible please? I can't see anything like that on the article page

    Nectariniidae

    So where is this tree? It's not in the paper and there don't seem to be supplements. Very anticlimactic!

    Taxonomy in-flux updates

    To maintain Lava Heron, 3 NW spp must be recognised (as Lava is closer to virescens than either is to striata). TiF treatment seems highly premature. We don't know what is going on with migratory and sedentary forms in eastern Asia and some of the island sspp are interesting and morphologically...

    Ardeidae

    Division amongst sampled OW sspp seems to be African/Indian Ocean v's Asian/Australasian and I have allocated sspp to follow this. However, there are some distinctive sspp on the Maldives & the Chagros Is and elsewhere which are not considered in this paper. A more thorough analyses would...

    Ardeidae

    The only explicit recommendation is for 3 species in the New World and this is sibling to a diverse Old World group.

    Mendales (2023) Ultraconserved elements resolve the phylogeny of a globally distributed genus, Butorides (Masters thesis) https://scholarworks.calstate.edu/concern/theses/hd76s649j Supports idea that NW & OW forms represent separate lineages; also that sundevalli is most closely related to...
