The BTO Website (www,bto.org.uk) gives a list of longevity records for all British ringed birds.
The group has three species which qualify.
Bittern
A nestling ringed at Leighton Moss on 8th May 2000 is still being sighted at Leighton Moss making it 7 years 8 months 23 days old at the last sighting.
Great Tit
A nestling ringed in a nest box in Eaves Wood on May 23 1976 was found dead 13 years 11 months and 5 days later. It was quite an adventurous bird for it had travelled 45 km NE to reach Appleby in Cumbria. Great tits rarely move more than 5 km
Bearded Tit
The BTO list gives the record for this reed bed species as 6years 4 months and 24 days. But looking through our data I was found an older bird. This was ringed on May 5th 2000 at Leighton Moss and finally retrapped 7 years 8 months and 23 days later- still at Leighton Moss!
