We still don’t know what this chat is all about – maybe a sort of contact call of ‘I’m here, it’s me’. These social calls are not as high-pitched as those they use to ‘echolocate’ and find their way around. They’re lower, quieter and sort of a warble.
There are a lot of questions to be answered about this chattering, but perhaps with Springwatch cameras inside a roost and local experts on the case too, we may discover more.
Watch this space, or warble!
