A request for help.
I saw this ringed Osprey in Banjul harbour, the Gambia last week. It was right at the edge of digi-scoping range, hence the poor image, but it was metal-ringed on the right leg (clipped ring, I think) and black colour-ringed on the left. I reckon it was '62' or possibly 'G2', and it may have had another letter at 90deg. to this.
Any help would be much appreciated.
