Hello. We have been trying to work out what bird is making this high pitched noise for a while now. Cannot see it, but it is always somewhere in our willow/silver birch trees. I've just got relatively clear audio so attaching the wav file and also a screen shot of what the noise looks like on the birdnet app.
Many thanks for any suggestions as to what it could be!
