Bravo! Quality birds Capers, and seem to be tougher than they used to be, great to hear you scored. Hopefully it'll follow the frequent pattern that a much dipped bird, once seen, suddenly becomes a lot easier to find again.
Hope the rest of the trip is a success.
A few days to bird at leisure round North Norfolk in winter is one of the finest things to do on the UK Birding circuit. I am quite jealous, and I wish you the best of luck. Enjoy the battered Koi in the chippy!
