I ordered a Bat Detector from the RSPB. It was a gift for Paul's birthday at the end of this month but he knew about it so there was no reason not to try it out.
It has a dial for different frequencies of sound and those frequencies can tell you what kind of bats are overhead. We have seen bats swooping over the garden especially on warmer nights when there are lots of insects about but weren't sure what they were.
We stood in the garden about 11p.m. and listened, pointing the detector in different directions then suddenly we heard the 'chitter-chatter' above and saw one bat swooping over the trees. The frequency told us that it was most probably a Long Eared Bat.
I expect we will be using this more over the next few weeks especially on warmer nights.
How exciting... I wonder what other species you will hear
