Soprano pipistrelle

[2] It is possible that these two species diverged from one another in the Mediterranean, resulting in the Soprano pipistrelle having the ability to thermoregulate at temperatures as high as 40 degrees Celsius.

One study, by Lourneco and Palmeirim, suggested that the reason for a preference for rooftops was because of the available thermal differences throughout a roof.

In a study done by Nicholls and Racey, the area frequented by a soprano pipistrelle was found to be small, around 487 ha.

The idea behind this alternative roosting could in fact be because of the torpor used by the Pipistrellus pygmaeus and the desire of the bat to be around 40 degrees C at certain times of its life, such as when in maternity colonies.

The Soprano pipistrelle only uses a small portion of its home range in order to forage and it is generally close to its day roost.

(Davidson-Watts and Jones) During the maternity colony times for the Soprano pipistrelle, there is an increased amount of wetlands within 2 km.

The majority of bats in a colony used one roosting site throughout the time of April to October most likely due to the need to be close to wetland habitats to acquire their specialized diet.

The frequencies used by this bat species for echolocation lie between 53 and 86 kHz, have most energy at 55 kHz and have an average duration of 5.8 ms.[4][5] [6] Dick, A. and Roche, N. 2017 Google Earth and Google Street View reveal differences in Pipistrellus pipstrellus and Pipistrellus pygmaeus roadside habitat use in Ireland.
