The International Ornithological Congress (IOC) leaving South Haven, Skokholm. The IOC had held their international scientific meeting in Oxford, with about 350 people from around the world attending. The week long Congress traditionally concluded with a 'long excursion', the British organizing committee chose Skokholm, the Pembrokeshire bird-island. The Navy provided two destroyers to travel between Tenby and Skokholm.
