Social calls from two adjacent populations differed in their peak frequencies, and possible hypotheses for this variation are given. The structure of P. kuhlii social calls was compared with those of the 45 and 55 kHz P. pipistrellus phonic types. Kuhl's pipistrelle calls lasted longer and showed lower values of minimum and peak frequencies.

Pipistrellus pipistrellus decreased the rate of social calls in response to the broadcast of songs of P. nathusii, yet they tended to increase the rate in response to the playback of their own Abstract. The advertisement calls of Nathusius' pipistrelle (Pipistrellus nathusii) show an unified structure: three main motifs which can be supplemented with additional two motifs especially during mating season. In May and June, a continuous social vocalization of quite unusual structure and composition was recorded apart from these standard calls. Echolocation calls of Nathusius’ pipistrelle are similar to those of the other pipistrelles. The peak intensity of the call is lower than the other two species, however, at about 38kHz (between 36 and 40kHz).

They find a nice mating roost and then sit at the entrance and 'sing' - they produce a specific type of social call known as an adveritsement call and the calls attract females to the mating roost. During a long-term study of advertising behaviour of Nathusius' pipistrelle in Southern Bohemia, social calls of a quite different structure and modified écholocation calls among typical social calls of this species were recorded during May and June 2006. The aim of this report is to describe this type of unusual social calls. Pipistrellus bats - social calls (pitched recording) by FFH Monitor published on 2017-03-09T20:56:08Z.

The bats were identiﬁed by using morphometric measurements and analysis of time-expanded echolocation and social calls.

The centred line in the middle of each bar shows the mean value and the shaded areas of each bar show the 80% confidence limites, that is, 80% of recorded calls fall into the shaded area. Pipistrellus nathusii(Keyserling and Blasius, 1839) is found from the Iberian Peninsula and British Isles to Asia Minor and Transcaucasia (Bogdanowicz, 1999; Russ et al.,2001). Although considered as a rare species in most European countries, it is thought that this could be merely the consequence of inappropriate sampling population of a migratory species, Pipistrellus nathusii, well known for its complex vocal advertising by males during the mating season.

We describe the most westerly known maternity colony of Nathusius’ pipistrelle bats (Pipistrellus nathusii). The bats were identiﬁed by using morphometric measurements and analysis of time-expanded echolocation and social calls. The roost, containing approximately 150 individuals, was located in a mid 19th century

The structure of P. kuhlii social calls was compared with those of the 45 and 55 kHz variation in the song of male Nathusius' pipistrelles (Pipistrellus nathusii).

The colour of the pelage is different depending on the season, in the winter time the fur is dark or greyish brown and in the summer time the colour is reddish.
