25/08/2012 This morning we retrapped blue tit V415348, a female that we first caught (and ringed) five years ago, but not in the intervening period. Where has she been? While unusual, this is by no means a record. Our oldest retrapped blue tit was 7.5 years (between ringing and recapture). Quite impressive for a small songbird with a typical lifespan (for a bird reaching maturit of only) 3 years. The maximum recorded age of a blue tit in the UK record is 9 years and 9 months - see BTO Birdfacts.
Today's totals (ringed and retraps) were:
