Roadrunner at the water bowl: Possessed by an alien? #Video

This roadrunner stopped by for a drink on a hot August afternoon and - perhaps overwhelmed by how good the water tasted - had a brief shuddering attack.

No doubt he (or she) was just doing a feather re-fluff, but in slow motion you can see his normally sleek plumage clump up and stand on end. It looks very odd. Was he possessed? Or did he perhaps have a toe in a light socket?
