The Incidence, Functions and Ecological Significance of Petrel Stomach Oils

چکیده
Recent research into the origins and compositions of the stomach oils unique to sea~birds of the order Procellariifonnes is reviewed. The sources of these oils, most of which contain mainly wax esters and/or trigIycerides, is discussed in relation to the presence of such compounds in the marine environment. A number of functions are proposed as the ecological roles of the oils, including their use as slowIy~mobilisable energy and water reserves for adults and chicks and as defensive weaponry for surface-nesting species. Suggestions are made for further research, particularly into physiological and nutritional aspects.
