Balcary Heughs/Cliffs

Wild windy walk along Balcary Cliffs today Kittiwakes, Fulmars, LBBs 1 Black Guillemot, Razorbills everywhere but sadly not a single Guillemot and I sat for an hour hoping! I have never seen so many very noisy Herring gulls all the way from Balcary Point to Castlemuir Fort ! They were flying around but feeding in the sea too. Are there shoals of small fish around at present? Anna
