Enduringly popular, the puffin is perhaps our most iconic species of bird, with their decorative bills and clown-like gait. In the air they are known for their energetic, beetling flight, while underwater these stocky little seabirds use specially adapted wings to propel themselves through the water in pursuit of fish. Until recently, surprisingly little was known about puffin ecology, thanks to their chosen breeding habitat being underground on remote islands or hard-to-reach coastlines. Now, Euan Dunn discloses all we have learnt about them through technological advances and provides a revealing account of their life cycle, behaviour and breeding, what they eat, how they interact in their busy colonies and where they migrate to in winter. Euan also exposes the mounting threats puffins face and offers advice on the best places to see them. The RSPB Spotlight series introduces readers to the lives and behaviors of our favourite animals, with eye-catching colour photography and informative expert text.
