We have just had notification of a ringing recovery for a Cormorant which apparently beats the oldest previous record by 4 years:-
Ringed on St Margarets Island on 27th June 1992 as a chick it has just been found dead at Pointe du Moustoir, Morbihan, France on 22nd January 2017.
We used to get many records from this area (usually caught in fishing nets) but almost none in recent years so this bird was 24 years and almost 7 months old compared with the 21yrs, 6months and 21 days previous oldest which was set in 1984.
The only caveat is that the finder reported a dead bird with no idea how long it had been dead!!
