Bioacoustics resources

This is the "bible" of bat bioacoustics, if you want to know everything about bats and their calls:

Barataud, M. (2015): Acoustic ecology of European bats: Species identification, study of their habitats and foraging behaviour. - http://www.nhbs.com/title/199366/acoustic-ecology-of-european-bats --> not only for european bat friends, the bioacoustics & methods section is universal

There are many many nice websites on batcalls, here is a subjective choice:

If you live in the northern hemisphere, we are very near to the end of the bat season, before the bats go to their wintering grounds. But if you live in a city, it could be worth going outside when the sun goes down and try to detect the last bats of the mating season doing their courtship calls.
