Blackbirds

On Sat 9th, we retrapped a Blackbird that was first ringed in September 2001. This happens to be the third "oldest" for the Group and at Priory. For the record, here are the "top ten" survivors of the last 20 years. They are all Priory birds!

420 Blackbirds were ringed in the park between 1991 & 2003. Only 1 in 35 of ringed Blackbirds reaches its 5th birthday; that probably means about 1% of all fledglings! [The above shows 1 in 52 reaching its 5th year but doesn't allow for emigration, mostly young females]
