Returning to its breeding sites in the spring after a winter spent far out at sea, the Kittiwake is a familiar sight around the coasts of Britain and Europe. A pale, medium-sized gull with a 'gentle' expression and bright yellow bill, the Kittiwake has been the subject of behavioural research since the late 1950s - one of the longest running studies in the world. In this Poyser Monograph, John Coulson summarises these decades of research, revealing amazing insights into the life of these gulls, with wider implications for the behavioural ecology of all colonial birds. There are sections on life at sea, nest-site selection, breeding biology, feeding ecology, colony dynamics, moult, survivorship and conservation. This book is essential for academics working on colonial species, and is also of great interest to birders who want to learn more about these elegant cliff-dwelling birds.
