If the birds were floating in water that would be pretty frictionless...the same water they dip into maybe.. . Sorry, just trying to confuse the issue.

Yes, gravity is involved... but I've already mentioned that and it appears to have gone sailing way above raaaaaaaids head some where, probably next to that 'UFO' in the video..

Anyway I now know more about bloody dippy birds than is healthy.. I'm off to annoy somebody in an FM/DM thread... At least the laws of physics apply over there.
