It isn’t very easy to hear as it’s shot from a mobile phone and the bird was being very quiet. But if you turn the volume up you should hear some faint bird chatter. That was coming from this male.
I fully expected when I bent down to find the source of the sound that it would stop, but he sat there very calmly. He didn’t flinch as I got my phone out to take this twenty second video either.
If I happen across him again I’ll just try for the sound recording as that may be clearer.
If anyone has a theory why he was, apparently, talking quietly to himself, I’d love to hear it.
