Auritus is distinctive and unusual compared to other European temperate zone swarming species (Furmankiewicz 2004b; Furmankiewicz et al. 2013). A strong male-biased sex ratio in spring may explain the intense bat vocalizations, both in terms of the high number and greater diversity of the social calls. Vocal activity was lower in autumn, probably due to a higher number of females visiting swarming sites and a lower male-biased sex ratio. The low number of females present at swarming sites in spring increases competition among swarming males.

Auritus emitted calls mainly in flight, but bats perched on a rock wall, tree trunk, or tree branch also produced social calls. Social calls were emitted near the entrances of the mines, as well as inside and outside the mines, although subterranean vocalizations were detected only at Skałki Stoleckie, where vocalizations were more intense inside than outside (Furmankiewicz 2004b). 2 The Social Organization and Behavior of the Brown Long-Eared … 33 Five basic types of calls at the swarming sites were distinguished: single, double, multiple (long and rapid series of single calls), undulating, and V-shaped (Fig.
