Re Bob 'n' Annie's post, those will have been the greylags that had flown over Carew Cheriton a few minutes earlier. See also my posts of 13 and 23 October. The numbers have been building over October, we are alerted by the sound and always rush out to see them. Yesterday there were more than ever, passing over in skeins and chevrons. 180 even more than I thought, but I can't see them all at once because of the trees. It's a daily occurrence: often they fly over early (I assume they've adjusted their clocks) but sometimes a load of them fly back quite soon, so geese seem to be coming and going all day.
There is a vantage point up the hill towards the Ridgeway where one has an overview of the whole area and could see where they're going - cf Rich C's identifying where the 23 glossy ibis were feeding in this way in January 2012. But I'm not sure I could stand up there for hours.
PS 15.30 2 V's of Canadas have just flown over Carew Cheriton, heading SSE, followed by more greylags. Clearly a major goose destination somewhere to the SE.
