Book excerpt: When studying the effects of parasites on natural populations, the avian haematozoa fulfills many of the specifications of an ideal model. Featuring a multitude of tables and illustrations, Avian Malaria Parasites and Other Haemosporidia summarizes more than a century of research on bird haemosporidians. For a long time, bird blood parasites served as important models in studying human diseases. Although now largely replaced, the wealth of data and research remain. With chapters addressing life cycles and morphology, pathogenicity, ultrastructure, geographical distribution, and illustrated keys to all known species of the parasites, this book is a masterful assessment of the biology of bird haemosporidian parasites.
