We recently found a bat skeleton with ring in a mine passage that was blocked in 1970, so it probably died then. The ring (2110 SPS) was placed on a female greater horseshoe bat on 26th February 1966.  It was caught in Canyon Cave, Cheddar Gorge in its first winter. It would have been born in the summer of 1965.

  Peter Bird of UBSS ringed 12 bats in Goatchurch on 4th March 1950.  He also found 2 bats he had ringed previously

  See UBSS log book No 5 on their website

  John Hooper, the father of Alison Moody was probably ringing bats earlier than 1965

The bat I mentioned earlier was found 5 miles NW of where it was rung.

Bristol Uni started ringing bats in 1949:
