Oh, another nice option if you're even remotely interested in sea birds is
The Isle of May , which has an astounding array of birds. (click the link for more info)
It's also got the added advantage of having the boat trip sail from Anstruther - home of Scotland's No.1 Fish and chip shop!
(and local to me!
)
Additionally, for your Raptor hunting, the
Falls of Clyde reserve is worth a visit. They've got a resident pair of peregrines there. It also has an added advantage of location. The falls themselves are stunning, as is the village of New Lanark. Always a good tourist stop. You could even manage to stop off for their regular Badger watch to see their badgers, if you're interested.
