Hello.
We live next to some woodland and are lucky enough to have a wide variety of birds - blackcaps, great tits, blue tits, blackbirds, garden warblers and more. I should point out that I'm in Eastern France. Recently I've been hearing this incessant call which can go on for 5 - 10 mins at time. It's new this spring and I think I've heard most of the other recognisable birds singing at the same time, so I'm bamboozled...
Thanks for your help!
