Social calls of the Common pipistrelle (Pipistrellus pipistrellus)
We start this year with type C social calls. A few that are lower in frequency (fishhook-shaped) than the regular echolocation calls of the common pipistrelle and a few that are higher in frequency. These social calls were recorded in the vacinity of a roost where numerous individuals were present, possibly housing a maternity group. The echolocation calls of a Nathusius' pipistrelle are also present in the recording.
A few more high frequency type C social calls that were emitted whilst two common pipistrelles were interacting with each other. The echolocation calls of a third common pipistrelle is present as well in the recording.

The following recording does not contain social calls, but these are the most oddly-shaped echolocation calls I have seen from a common pipistrelle.
