Shorebirds are model organisms for illustrating the principles of ecology and excellent subjects for research. Their mating systems are as diverse as any avian group, their migrations push the limits of endurance, and their foraging is easily studied in the open habitats of estuaries and freshwater wetlands. This comprehensive text explores the ecology, conservation, and management of these fascinating birds. Beginning chapters examine phylogenetic relationships between shorebirds and other birds, and cover shorebird morphology, anatomy, and physiology. A section on breeding biology looks in detail at their reproductive biology. Because shorebirds spend much of their time away from breeding areas, a substantial section on non-breeding biology covers migration, foraging ecology, and social behavior. The text also covers shorebird demography, population size, and management issues related to habitat, predators, and human disturbances. Throughout, it emphasizes applying scientific knowledge to the conservation of shorebird populations, many of which are unfortunately in decline.
