Book Description
In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics.

Book Description
The northeastern seaboard of Canada and the United States, extending from Labrador to Cape Cod, was the first region of North America to suffer from human exploitation. Farley Mowat informs extensive historical and biological research with his direct experience living in and observing this region. When it was first published more than 20 years ago, Sea of Slaughter served as a catalyst for environment reform, raising awareness of the decline and destruction of marine and coastal species. Today, it remains a prescient environmental classic, serving, now as ever, as a haunting reminder of the impact of human interest on the natural world.

Book Description
An authoritative overview of the biology of the Kittiwake, Rissa tridactyla. 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.

Book Description
Birds as Monitors of Environmental Change looks at how bird populations are affected by pollutants, water quality, and other physical changes and how this scientific knowledge can help in predicting the effects of pollutants and other physical changes in the environment.

Book Description
Seabirds are attracted to large offshore structures such as oil drilling platforms. This report presents a review of the literature on seabird attraction to offshore platforms and of the scientific feasibility of monitoring fluctuations in the spatial & temporal distributions & abundances of seabirds from support vessels. Sections of the review cover the following: seabird distribution in the north-west Atlantic; influences on seabird attraction to offshore platforms, and recommendations for surveys of avian associations with offshore platforms and for quantifying seabird mortality due to offshore platforms; and seabird monitoring from ships, including seabird counting methods, experimental design, and research design. Finally, considerations relating to assessment of seabird vulnerability to oil pollution are discussed.
