At Pulborough Brooks on Saturday morning I watched some flocks of Greylags coming into land on the North Brooks, and I noticed that as they all were coming in to land, many or most of the individual birds would momentarily flip over so that they are for-all-intents-and-purposes flying upside down for a second.
It does look quite odd, especially when they're coming in a direction towards you! But I was wondering if anyone knows what they're doing when they do this? Is it a signal to the others saying "ok chaps, time to land for tiffin!", or is it a way of slowing down as I did notice that that action does seem to slow the individual down?
Thanks
