Enduringly popular, Puffins are perhaps our most iconic species of bird, and are the most immediately identifiable of seabirds with their decorative bills and clown-like gait. Yet when they take to the air they wheel and turn with great agility and underwater these stocky little birds use short specially adapted wings to propel themselves through the water in pursuit of small fish. Surprisingly little was known about Puffin ecology until recently thanks to their preferred breeding habitat being underground on remote islands or hard-to-reach coastlines. Now Euan Dunn discloses all we have learnt about them as a result of 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. Each Spotlight title is carefully designed to introduce readers to the lives and behaviour of our favourite birds and mammals.
