KEY POINTS

1 Check the North Bay for passing gulls on their way to Scalby Mills, and look out for porpoises and dolphins. 2 The castle grounds have a rich history of turning up rarities from spring to autumn.

3 Low-nesting Kittiwakes offer great views along the Marine Drive. Also a great Peregrine site.

4 The harbour is worth a look at any time but winter is a great time to find tame Turnstone and anything from divers to grebes.

5 South Bay is yet another location to look for sea ducks, divers and gulls.
