Many thanks for sharing your observation with iNaturalist and the AfriBats project!
You can read more about slit-faced bats here: http://www.inaturalist.org/taxa/41184-Nycteris
In general, they are insectivorous bats, which use their huge ears to detect the rustling noises produced by their prey, which includes beetles, cockroaches, scorpions among other things.
If you have a large tree full of bats, it’s likely to be of a different species. Please take a picture and share it with the project, we’re happy to provide identifications and further background.
I will hack myself through the rain forest and check out the big tree and try to make pictures. As far as I remember those bats were larger than our little Barney.
Now I also need some advice. Barney and friends have found nice spots to hang inside all our island building but some spots I rather not have them – like above the dining table. How can i convince them to move to the room next door?
Would be wonderful if you could snap a picture of these bats – I’m sure they are of a different species.
Would you mind having the exclusion discussion at iNaturalist and posting your question as a comment next to your observation? This way, other project members would profit from it and can also chime in with suggestions!

Would you add your bat photo as a citizen-science observation to the AfriBats project on iNaturalist?:

AfriBats will use your observations to better understand bat distributions and help protect bats in Africa.
Please locate your picture on the map as precisely as possible to maximise the scientific value of your records.
Many thanks!
PS: it’s a slit-faced bat, Nycteris.

Dear Jacob,
Thanks you for the information about Barney. We have a humongous tree full of these little creatures. Are they fruit bats – in general terms?
I will upload the picture and give Barney more egards in our picture.
Nice day,
