No red tape on right leg band so that would be Lucius ... Lucius is presumably the younger of the two - at banding he was just a bit more fuzzy than his brother. Interestingly, Lucius was the one who slid/slipped his way off the corner of the nestbox onto the ledge first. He was the one who was sitting on the edge of the new Police HQ a few days ago which is how we spotted the boys - Pericles was tucked behind a communications unit for most of our visit - if it hadn't been for Lucius on the railing, we'd have had to be very lucky to catch sight of Pericles!
