Unusual bird call, Provence (1 Viewer)

[Racmort]

Hello
I’m a birdsong enthusiast, and have joined this especially to try and identify an unusual song here in Provence, France. I’ve attached a recording clip, but I describe it as a repeated three note call, rising perfect fourth which immediately drops an octave. Eg G-(high)C-(low)C.
Please can someone put me out of my misery and identify it?!
Thanks.

Ah, thanks. Good point. I can't work out how to do it via my phone (only offers adding documents). I'll try again in a sec.
