Early radar ornithology mainly focused, due to limitations of the equipment, on the seasonality, timing, intensity, and direction of flocks of birds in migration. Modern weather radars can detect the wing area of the flying, the speed of flight, the frequency of wing beat, the direction, distance and altitude. [3]
The common pipistrelle (Pipistrellus pipistrellus) is a small pipistrelle microbat whose very large range extends across most of Europe, North Africa, South Asia, and may extend into Korea. [2] It is one of the most common bat species in the British Isles. In Europe, the northernmost confirmed records are from southern Finland near 60°N. [3]
Some early bat detectors used ex-Navy low frequency radio sets, simply replacing the aerial with a microphone and pre-amplifier. It is also possible to modify a portable Long Wave radio to be a bat detector by adjusting the tuning frequencies and replacing the ferrite rod aerial with a microphone and pre-amplifier.
Nathusius' pipistrelle (Pipistrellus nathusii) is a small bat in the genus Pipistrellus. It is very similar to the common pipistrelle and has been overlooked in many areas until recently but it is widely distributed across Europe .
A 2021 study attempted to resolve the systematic relationships among the pipistrelle-like bats of sub-Saharan Africa and Madagascar, with systematic inferences based on genetic and morphological analyses of more than 400 individuals across all named genera and the majority of described African pipistrelle-like bat species, with a focus on ...
Bat detectors are the most common way to identify the species of flying bats. There are distinct types of call which can indicate the genus, and variations in pattern and frequency which indicate the species. For readers not familiar with the different types of bat detector, there is further information below and elsewhere.

Savi's pipistrelle is a small species of bat with a head and body length of between 1.75 and 2 inches (44 and 51 mm) and a forearm (elbow to wrist) length between 1.25 and 1.5 inches (32 and 38 mm). It weighs between 0.26 and 0.35 ounces (7.4 and 9.9 g).
