Whilst not the greatest photos in the world, these images show nicely the damage to it's wing. Tee primaries on its left wing have been, presumably, removed by a shotgun blast. Close-up you can see the jagged edges. It doesn't seem to be harming its ability to fly or catch fish although whether it is this damage or the fact it is a juvenile which is causing it to remain around is open to conjecture.
Then finally we sat in the hide again all afternoon and it popped up again between 3 and 4, still not fishing but giving some really close-up views as it scanned the lake presumably looking for any fish near the surface. It seems happy and with the weather still quite mild it will be interesting to see how long it remains
