Monogamy: Mating Strategies and Partnerships in Birds, Humans and Other Mammals

Why do males of some species live with a single mate when they are capable of fertilizing more than one female's eggs? Why do some females pair only with one male, and not with several partners? Why do birds usually live in pairs and feed chicks together whilst mammals often live in larger groups with females rearing their young without male help? These questions form the central theme of this book. Social monogamy is a complex, multi-faceted phenomenon that does not always correspond with reproductive monogamy, so a paired male may not necessarily be raising his own offspring. Exploring the variables influencing and maintaining the fascinating diversity of social, sexual and reproductive monogamous partnerships in birds, mammals and humans, this book provides clues to the biological roots of monogamy for students and researchers in behavioural ecology, evolutionary anthropology, primatology, zoology and ornithology.
