    Just to clarify, B. (rufinus / buteo) cirtensis is strictly resident, breeding in Africa north of the Sahara; B. r. rufinus is partially migrant, breeding SE Europe eastwards; the type locality of rufinus in Sudan / Ethiopia is in the wintering grounds, not the breeding area :t:

    Actually, you'd be surprised. On wiki commons, I've found (and dealt with, so they're not there any more) several Erithacus rubecula pics put in Category:Turdus migratorius, and vice-versa. And numerous other examples with other cases of incorrect vernacular name sorting. You might know enough...

    But they're not related to Pheucticus ;)

    They are a taxonomic unit, but not a complete one: calling them 'Scrub-jay' but not calling other Aphelocoma species 'Scrub-jay' as well, suggests that e.g. Mexican 'Non-scrub' Jay and Unicolored 'Non-scrub' Jay, are more closely related to e.g. Steller's 'Non-scrub' Jay, than they are to any of...

    Wow! I don't think it could cross the Pacific on its own, but I suspect that one could easily be carried across by a ship, fishing from the side of the ship and carried east without its realising. It need not be fed or handled by people on board, just catching natural food while using the ship...

    Though they missed a trick on the English name . . . since Haida Gwaii is rainforest, they should've just called it 'Saw Wet Owl' 8-P

    Common Kingfisher: fascinating record! Hope its identity gets verified satisfactorily. While dealing with it, perhaps the NACC could settle the correct scientific name for the species under ICZN rules? See posts 73, 75-6, 78-79 in this thread.

    Of Sarkidiornis, why not follow IOC and use Comb Duck (the New World species) and Knob-billed Duck (Old World)? Or is following IOC too strong a political anathema to NACC?

    What about the possibility that black bills evolved just once, in Europe, then a vagrant male (so no mtDNA input) black-billed bird crossed the Atlantic and settled in an orange-billed ancestral Cabot's Tern colony in N America? If black is dominant over orange, this could work? And the new...

    From the IOC web page, go to the drop-down from 'Updates' and select 'Proposed Splits/Lumps'. Or just click here to go direct; it's currently 16th down the list :t:

    AOU-NACC Proposals 2020

    The data used to support this split, also necessitates the split of Cabot's Tern from Sandwich Tern (accepted several years ago by IOC; still not yet by AOU). It would be odd, and very inconsistent, if AOU accepted this split, while still rejecting the Cabot's Tern split. Surely the two should...

    It's actually a hybrid Nahuatl-Spanish name; 'Ocote' / 'Ocotl' is Nahuatl for pine, 'ero' a Spanish word ending which can mean 'associated with'. So it effectively means 'Pine Bird'.
