The first complete monograph on these birds for 110 years. It describes and illustrates 22 species, distributed over Australia, Papua New Guinea, Indonesia, The Philippines, and some southwest Pacific islands. These birds are known for incubating their eggs in mounds, burrows or sand, with the young emerging fully able to care for themselves. As well as full species descriptions, there are general chapters on biology, feeding, breeding, evolutionary relationships and conservation. Information on range, status and distribution is also given. The colour plates show adults and juveniles.
