Social call pipistrellus nathusii

The social organization of the pipistrelle bat (Pipistrellus pipistrellus) was studied by means of bat boxes in southern Sweden. The males set up territories around a roosting site in the beginning of the summer at the same time as the females formed nursing colonies. After breeding, the females joined the single males in their day roosts establishing transient mating harems. Subsequently Sequences of the advertisement calls produced by male Nathusius’ pipistrelles (Pipistrellus nathusii) during the autumn mating period were recorded from individuals at two separate sites in Antrim, Northern Ireland, in August 2004.

These vocalisations are called social calls and are emitted by both common and soprano pipistrelle males during prolonged song-flights. However, Barlow & Jones concluded that these social calls were used in food defence when insects are scarce rather than in social displays .

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.
