Barra Best presents a natural history series revealing how endangered animals across the UK and Europe are being helped by conservationists. Barra reveals how a tiny pair of islands lying just outside Dublin Port have become the unlikely home for a conservation project helping one of Europe’s most endangered breeding birds. Scientists off the coast of Scotland attempt to place cameras on the world’s second largest fish, while in the small Swiss town of Bellinzona, ringing some simple changes have had a big benefit for a mysterious creature of the night. In Amsterdam, volunteers Thea and Gert explain how, as the city’s skyline undergoes changes, they’re providing a new home for a creature that spends nine months of the year in the air.
