S3E28 This week Steve is joined in a Derbyshire churchyard by Jon Russ who is an expert on bat echolocation calls. They discuss how Jon got into studying bat calls, his latest book on the subject and his passion for Nathusius’ pipistrelle bats. Jon's latest book "Bat Calls of Britain and Europe" is available from Pelagic Publishing and is aimed at anyone interested in bat echolocation. It contains introductory chapters to the subject as well as more advanced topics such as sound analysis. As Jon says in this episode if you want to get into learning about bat calls the best place to start is to get hold of a bat detector. Your local bat group are likely to be able to lend you a detector and you can learn more about them on our website here. Jon's other passion is Nathusius' pipistrelles and he runs the website dedicated to this species containing distribution maps, identification tips and other information about their ecology.  Listen to our earlier episode about Nathusius' pipistrelles with Dan Hargreaves here.Bat Calls of Britain and Europe Bat Detector InfoNathusius' pipistrelle websitePlease leave us a review if you can, it helps us to reach a wider audience so that we can spread the word about how great bats are.Join the conversation on social media using #BatChatProducer: Steve Roe @SteveRoeBatManSupport the showPlease leave us a review or star rating if your podcast app allows it because it helps us to reach a wider audience so that we can spread the word about how great bats are.
