Living on the coast for most of her life, Marianne Taylor has spent a lot of time in the company of wild seabirds. Whether she's swimming in the sea, doing some coastal birding or looking out of her window at home, she is fascinated by the dynamic activity of seabirds on land, in the air and in the water.The UK hosts vast numbers of overwintering seabirds from home and further afield, and British seabird populations are of global significance thanks to the breeding colonies dotted around our coasts. But our coastal wildlife is under immense pressure through coastal development, pollution, over-exploitation of fisheries and the growing impact of climate change. Our seabirds have become bellwethers for any impending climate-related crises that loom off our coasts, and they face the additional threats of entanglement with discarded fishing gear, plastics ingestion and avian influenza outbreaks.For now, at least, visiting a breeding colony on one of our coasts is a spectacular and exhilarating wildlife experience. But these raucous, crowded cliff-side cities are only a tiny part of the seabirds' world. When she swims in the sea, Marianne can share the water with seabirds in the most natural and non-invasive way and experience the sea as they do.For her new narrative, Marianne will travel by public transport to visit Britain's hotspots and swim among seabirds to experience their day-to-day lives at sea level. She'll write about how sealife and sea-loving humans can interact and will relate the story of our seabirds from her unique perspective as a lifelong birdwatcher and year-round sea swimmer. Leading readers through the major and minor events that punctuate the seabird calendar, Marianne will unique insights into some of the most important seabird populations in the world. And she'll celebrate the diversity of seabirds we are lucky to witness around our coastlines.
