We share the earth with a wide variety of animal species, each of which brings something special to the diversity of the planet. By knowing more about how animals behave and live, we gain a greater understanding of how life evolved and the importance of biodiversity. This volume provides a complete guide to those birds that have evolved a trait that would seem to harm their ability to survive - flightlessness. Flight has its advantages - why would some birds be flightless?Flightless Birds covers the loss of flight in birds, both permanently after years of evolution, and temporarily as a result of unusual molting behavior, and those species that are in various stages of losing their flight.
