Sorry to give you a video but it's rather small in snaps.
As I said yesterday, the long eyebrow stripe and light colour make it a Whinchat for me as well.
I've just checked our observations in SW France & last year the first Whinchat was 7 April & none seen so far this year. So unlikely to be an early arriver. It could be an odd one that didn't migrate, as happens sometimes.
EDIT : Sorry mods clicked on spam instead of EDIT by mistake (well it's you that put them next to each other! LOL)
