Today we delved a little deeper into using the bat sensors. There are 3 categories of sensor, the more high tech of which record sonograms of the bat calls. These can then be plugged into computer programmes which produce a sonogram (graph) of the call.
The finely tuned ear of a bat lab scientist can identify the species from the graph as you can determine with great accuracy the frequency of the call and it’s duration.
There are even programmes which have some of the bat species sonograms already inputted and the new call is immediately identified .
We also learned a great deal about wind farms and their impact on bats-much of the data relates to migratory bats but Irish bats don’t seem to act in this way. So Una is collecting data investigating the impact of Wind farms on Irish bats.
Collecting bats for identification is a huge part of bat lab research and we had a chance to put up the mesh trap and the Harp trap.
