Well, even if nobody else thinks they are amazing, I do.
While driving around the south of France, include Provence and The Camargue, I spotted quite a number of horses grazing, and underneath them and surrounding them were whole flocks of strange white birds.
This pic has a somewhat bad quality: I took it while driving and (no kidding!) being followed by a police car!
But I think you get the idea:
I have no idea what kinds of birds these are – but I assume they eat any small insects that appear when the horse grazes.
