Snow goose on my life list

Hi
Is my sighting of aSnow Goose at Blenheim Palace a valid sighting or Should this be regarded as a captive bird?
Cheers
Ian

Hi Ian - I think most birders would not consider this a wild bird

Best wishes

Not quite as simple as that because the species is on both Categories A and C of the British List so also countable on an official list if it is part of a self-sustaining population? The Blenheim population was mentioned in the 2005 Ibis paper but at that stage, it was not self-sustaining. Not sure what has happened in the 12 years since?

All the best

Paul

Thanks both
I’ve deleted it to be on the safe side.
down to 130 now though so will have to take it a bit more seriously this year!
Thanks again
