I saw a flock of swans flying south high in the sky this afternoon and am struggling for a firm ID.
Whooper Swan is the main wintering species in Hokkaido but normally don't arrive this early. Bewicks Swan occur on passage only (they winter further south).
So which ones are these? Very heavily cropped (100% or more) but I hope enough detail remains.
I'm thinking (hoping) they might be Bewicks but am not sure, any help appreciated........
They seem to have less yellow than black, of course it's impossible to see where the nostril is on the bill at this resolution...........and of course the individuals have somewhat variable bill patterns anyway.
