Abstract Echolocation behaviour and the structure of calls of Pipistrellus pygmaeus and Pipistrellus pipistrellus were studied by using a time expansion bat detector.

For each of the species, multivariate analysis of variance (MANOVA) indicated significant differences in calls produced inside the experimental room and in the open. Paired t ‐tests and MANOVA were also used to reveal influences of interindividual contacts in each of the cryptic species on the spectral patterns of call variables. Differences were found in the spectral variables of echolocation calls of an individual flying in the room alone and in a group of conspecifics.

We found that bats flying in a group modify the parameters of their echolocation signals according to the presence of other individuals of the same species. These differences can indicate jamming avoidance and recognition of own echoes. However, they did not change the parameters if individuals of another species were present.
