Seawatching

I'll be at SeaWatch SW for the first few days of August, hoping to add a couple of shearwaters to my British list if my identification skills are up to it. I haven't been to Cornwall for years, except to catch the Bay of Biscay pelagic in 2006, which did provide my only record of Balearic Shearwater, as well as Great Shearwater, Sabine's Gull and Storm Petrel.
