RY31120 Redwing
First Year 19/11/2018 Billinge Hill, Billinge, Merseyside.
Found dead 17/11/2019 Oil Rig Snorre B, Tampen, North Sea. 938km NNE
It wasn't freshly dead when found but is still likely to have reached the rig the same autumn as I wouldn't have thought a the body of a small thrush like a Redwing would last long on an exposed rig or remain unfound for very long either.
