In truth it is a night-time ramble at which bats are present. We had these fascinating little devices called bat-detectors which pick up the frequencies of the bats passing by. Every bat makes a different sound, but they are not perceivable to the human ear. This machine picks up the clicking slapping sounds they make in order to form an echo-location picture (we like to call this a bat-signal. Another Batman joke!). In a group you can hear the clicks build up faintly from one end to another as a bat whizzes over head. We actually saw a lot, but mostly pipistrelles. There were other bats around but they move so incredibly fast that it was often more of a black smear passing by.
We did this at the London Wetland Centre and they do them every Thursday so I would seriously recommend it. There's a talk on bats first, followed by a lovely post-sunset early evening walk around lakes with a guide and the use of bat-detectors. It's also rather romantic if you are looking for an unusual date. I would quite like to go to the London Wetland Centre again some time when it is day time and explore the whole thing. We did however have a little bat-picnic before our bat-walk. I am sorry that I don't actually have any pictures of bats from the evening. I would have had to have brought a tripod and have some incredible skills to capture the kind of photos I was imagining. I do have a few pictures of the area and my outfit as the sun was setting though.
