Almost 97% of the social calls of brown long-eared bats that were recorded during a research to social calls of brown long-eared bats conducted by Murphy (2012) fell into the type C category (Middleton et al., 2020).
Type C social calls of the brown long-eared bat are often emitted as a single call, in a group of two calls, in a group of three calls or in a long series of calls (Furmankiewicz, 2004 & 2016; Furmankiewicz and Jones, 2021).
The following type A, type B and type C social calls were recorded with a batlogger M that was placed underneath a maternity colony of brown long-eared bats whom were roosting in the roof of a barn.

The following recording was made outside with no known roost in the area. The look and the sound of the calls look almost identical to the type C social calls of the brown-long eared bat recorded by J. Furmankiewicz (Middleton et al., 2020) and are very similar to the social calls shown in the last snippit of the previous recordings. No other calls of this bat were recorded. In this recording, two groups of three calls are clearly visible. Later in the recording, groups of two calls are present too.

The following calls were emitted by a flying bat, recorded from a garden.
