Abendlich aufsteigende Mückenschwärme sind hier schnell "weggeputzt" wir können bis in die Nacht gemütlich im Garten und auf der Terasse sitzen.....
How do Citizen Scientists help?
This is where you come in! Humans are absolutely fantastic at hearing and seeing the difference between a bat and a non-bat call, the different types of calls and what sequence a call belongs in. We need your help going through our recordings to pick out the different calls. The ultimate goal is to use your classifications to make a new automatic programme that researchers all over the world can use to extract information out of their recordings, making it really easy to track populations of bats. This will make understanding how bat populations are being effected by global change much easier.
Each region of the world has different bats, the areas with the most bats or ‘bat hotspots’ are places like northern South America with over 200 species in an area! Bat Detective aims to develop these new automatic programmes for bats all over the world but we are starting our journey in Europe, where we know a lot about the bats already. Over the course of the project we will release data from more areas from around the world. In Europe, there are over 40 species of bats, they all use echolocation to eat insects. Most species hibernate to escape the food shortage in insects during the winter. Some other bat species migrate to other parts of Europe during winter, but we know very little about which species do this. In the summer, most species split into separate female and male roosts (in buildings, tree cavities, under bridges, caves), where the males just chill out whilst the females busily gather insects to raise their baby. During the autumn the males and females come back together again to mate and then don’t emerge again until the next spring. Check out the Bats page to see some examples of European bats whose calls you might see and hear in our recordings!
