The process of bird speciation, or how one bird species turns into another, has fascinated biologists and bird watchers ever since Charles Darwin put forth on The Origin of Species in 1859. In Speciation in Birds, Trevor Price, a University of Chicago professor and leading expert in the field, has written the most authoritative and modern synthesis on the topic. In clear and engaging prose and through beautiful illustrations, Price shows us why the field is as exciting and vibrant as ever. The book will appeal to scientists of all stripes and bird enthusiasts who care about the science behind their passion.
