a panoramic view of approx 40-50 Redshank on the prom. Back to Westgate with a vengeance. These are 2 legged unlike the the small fling which return every year with only 1 leg. A few of these are also ringed but I am unable to get a close up of these, can anyone work out from these pics the rings? How close do you need to get and do you need to see numbers etc to be any good. Does colour help for return of ID?
