About This Book
This work investigates the anatomy, mechanics, and diversity of avian flight, explaining wing structure, musculature, feathers, and air-sacs while comparing bird flight with that of bats and insects. It traces evolutionary origins and links form to function through variations in wing size and shape, and describes soaring, hovering, plunging, and silent muffled flight with attention to courtship displays and social migrations. Practical guidance is offered for identifying species on the wing by silhouette, wingbeat, and behavior. Illustrative species examples and natural-history observations illuminate how flight serves feeding, courtship, and escape.
