Six GoodGymers went on a bar survey! Did you know that t and r are side by side on the key board? This time though, it was a bat survey, not a bar survey!

We met Ken and Philip with the London Bat Group who guided us on our survey along the River Thames counting bat passes with our bat monitors tuned into various frequencies. The bat monitors amplified the echolocation calls of the bats into the audible range of human hearing. We counted several 100 bats in the night with all the data recorded for a scientific study that Ken started in 2008 with the UK Bat Conservation Trust. And luckily half of the group finished the bat survey along the Thames at a pub to conduct a bar survey!
