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?

Chinese BlackbirdTurdus mandarinussowerbyi/mandarinusChinese Blackbird T. mandarinus including sowerbyi, but not intermedius, is split from Common/Eurasian Blackbird (Rasmussen & Anderton 2005; Collar 2005; Robson 2008; Nylander et al. 2008; H&M 4).
Tibetan BlackbirdTurdus maximusTurdus maximus is split from T. merula (Rasmussen & Anderton 2005; Collar 2005; Nylander et al. 2008).
Indian BlackbirdTurdus simillimusnigropileus/simillimus/bourdilloni/kinnisiiTurdus simillimus is split from T. merula (Rasmussen & Anderton 2005; Collar 2005; Nylander et al. 2008).

This is from IOC - Looks like a catching up proposal

I don't think there's a tibetanus?

How do they know it was not a falconry bird flown by its owner? Legs are not clearly visible. This would explain why such a huge bird appeared and disappeared again without trace.
Falconers in the US use native species almost exclusively, and there are records of every bird kept by all falconers anyway.
There is a Steller's Sea Eagle at the Fort Worth Texas Zoo.

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."
