    based on real world observations, pulverulentus should remain separate, as, Peters had it. But indicus, melanotus, poliocephalus could likely be re-lumped. I don't have personal experience beyond these

    possibly a reassessment of the work by Garcia-Ramirez and Trewick that led to this split

    Latest IOC Diary Updates

    Lumping the swamphens back to the Peters checklist state would make sense to me, given the very widespread hybridisation in many areas. Philippine P. pulverulentus is worth retaining separate as it seems to maintain some ecological differences and on the evidence so far to have limited if any...

    Yes, already split by Birdlife/Lynx. Still extant on Panay-Negros, but no recent records from elsewhere in the West Visayas.

    Yes. The south Philippine taxa may eventually get split from the nominate too.

    Columbiformes

    It is possible I don't fully understand what the trees of figs 3, 4, 5 represent, but it appears to me that arcanus is closest to melanospilus (of all the other Ptilinopus) in the diagrams.

    Columbiformes

    Please don't describe a new genus until the stats have been put under a microscope. The specimen has a lot of similarities with a juvenile Black-naped FD. See here for example ML609413533 - Black-naped Fruit-Dove - Macaulay Library and it does occur very close to this species in figs 3, 4, 5.

    Is this available anywhere beyond the abstract?

    Robins are flycatchers?

    Thanks. I only recalled a part of it correctly then :( The Philippine avifauna has yet to fully recover from the lumping bonanza of the 20th century.

    Robins are flycatchers?

    IIRC (I don't have the book with me just now) Delacour and Mayr lumped goodfellowi, albigularis and insignis as one species

    Robins are flycatchers?

    It is listed as being collected on Panay, so there is a very limited number of confusion species, none at all likely.
