One of the most unforgettable experiences of my holidays in Mallorca was the close encounters with shags. They sat on the rocks near the beach preening or drying their wings, or just standing still, upright like dark statues. Often people would sit on the rocks or swim by them and they would take no notice most of the time. While I was snorkelling, I saw a young one take to the water and followed it, and it allowed me to watch its diving prowess at close range, as it swam to the sea floor looking for food. Absolutely magic!
