Re 'Proposal 2021-C-5: Treat Eurasian Blackbird Turdus merula as four species', presumably tibetanus, simillimus & mandarinus would attain full species status? Are the allotted subspecies specified?
At a big name AZA zoo like that, a bird of prey escapes would have made the news. I'm not sure they still have the bird, anyway, that photo is from 2016. I think there is no way that this sea eagle, if real, was anything but a natural vagrant.
2021-C-15 Add Common Wood-Pigeon Columba palumbus to the Main List.
Pyle et al. (2020) mentioned a May 1935 record by Alan Brooks off Newfoundland on board a ship crossing the Atlantic in a westerly direction (Gosselin 1992). The position of the ship when the bird was recorded is not known. "...tomorrow at noon we will be within sight of Cape Race." https://collections.mun.ca/digital/collection/osprey/id/4435 .
