Hi Herring,
Try the Harthope Valley in the Cheviots: Goshawk, Peregrine, Red Grouse, Common Sandpiper, Tree Pipit, Dipper, Redstart, Whinchat, Wheatear, Ring Ouzel, Wood Warbler, Pied Flycatcher, etc. Grid ref NT975250 and southwestward from there.
The Farnes are always good, though it is a little early for many terns to be in yet.
