Wight and/or Brighton could be the home of the wanderers. Close enough to both. Now, Sea Eagles? Isle of Wight? Shall keep eyes peeled. Seen some in the past; mainly en-route somewhere at high altitude. Once, decades ago in Norway on hols came past some rocks on edge of Fjord and there was this chap only 6ft away, just sat there. Tried to ignore me, failed and lazily pounded off over the water.
