By Peter M. Bennett,Ian P. F. Owens

Why do albatrosses hold up replica for the 1st 12 years in their lifestyles whereas zebra finches breed of their first yr? Why are fairy-wrens so sexually promiscuous whereas swans exhibit lifelong monogamy? Why are over 1 / 4 of parrot species threatened with worldwide extinction whereas woodpeckers and cuckoos stay safe? a few of these issues are vintage difficulties in ordinary and sexual choice, whereas others have arisen within the final decade, similar to version in genetic mating structures or extinction hazard. Birds provide a special chance for investigating those questions simply because they're enormously well-studied within the wild. by way of utilizing phylogenetic comparative tools and a database of as much as 3,000 species, the authors determine the ecological and evolutionary foundation of a lot of those interesting questions. in addition they spotlight final puzzles and establish a chain of demanding situations for destiny research. this is often the main entire reappraisal of avian variety in view that David Lack's vintage "Ecological Adaptions for Breeding in Birds". it's also the main huge program of contemporary comparative tools but undertaken. This novel process demonstrates how an evolutionary standpoint can exhibit the overall ecological methods that underpin modern avian range on an international scale.
