    I think it's more clear in the Clements update file: The Malay Peninsula populations previously treated as a subspecies of Sunda Scops-Owl (Otus lempiji) are hereby moved to Collared Scops-Owl (Otus lettia), restricting that species to Indonesia, Borneo, and Con Son Island, Vietnam and...

    Doesn't the paper say that all domestic birds are from livia?

    But Bubo as defined now is very unlikely to be wrong. There's at most 8 species in Ketupa that might change genus when new studies come out. If you lump everything in Bubo now, you need to change 15 species later...

    These are now all included in Ketupa, which seems wrong: African Eagle Owls (Nyctaetus): lacteus, shelleyi, leucosticta & poensi South Asian Eagle Owls (Ptiloskelos): nipalensis, sumatrana Fishing Owls (true Ketupa) - unknown if coromandus & philippensis belong here Also, Scotopelia is...

    In my opinion, Ketupa is still overlumped, there are some very different birds in there A split between Ciccaba & Strix should be between the old world & new world groups... which seem rather alike?

    Has the WGAC published a list?

    I noticed this on the last entry in IOC updates: WGAC must have a proposal system in place. I hope the proposals will (eventually) be public, as SACC does. Always very interesting to see the reasoning behind a decision.
