In this book, fourteen classic studies of bird behaviour are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Often there is a battle of the sexes, as individual birds behave in the way that serves their best interests. Introductory and concluding chapters review the latest thinking on this fascinating subject. - ;Some birds mate for life, while others have many partners. In this book, fourteen studies are brought together to compare different partnership patterns from ecological and evolutionary perspectives. The subjects have been chosen to include the same species living in different habitats (Sparrowhawks) and at different population densities (Great Tits). There are comparisons between closely related species (Mute Swans and Bewick's Swans). The studies span the globe and the behavioural gradient, from Iceland's strictly monogamous Whooper Swans to Australia's sexually promiscuous Splendid Fairy-wrens. In all cases, sexual and social relationships strongly influence a bird's survival and breeding success. -
