In these 12 vividly illustrated lessons, biologist and bird expert Professor Bruce E.
Fleury takes you on a journey through the amazing world of birds-their evolution, their lives in the wild, and the science that underlies their behaviors.
Whether you’re an experienced birder or a newcomer to the bird world, you’ll gain a deeper appreciation for the beauty and diversity of our feathered friends.
Begin by contemplating the integral connections between birds and dinosaurs. Examine mounting evidence that birds not only evolved directly from dinosaurs, but also that they are themselves dinosaurs. Consider how bipedal reptiles gained the ability to fly, becoming birds, and how the cursorial (from the ground) and arboreal (gliding) theories of the origin of flight may intersect.
Delve into the fascinating aerodynamics of bird flight. Grasp how a bird's wings operate as an airfoil; study the forces of lift, weight, thrust, and drag; and how birds take off, land, and glide. Then explore the astonishing properties of bird feathers, as they control speed, altitude, and direction. Learn about the structure, the types, and the many roles of feathers in bird behavior.
Discover the remarkable physiological features of birds that undergird flight. First, note how and why feathers evolved. Then, investigate the high metabolism of birds - they must burn energy at an astounding rate. See how birds are adapted for flight by many weight-reducing factors, and how their respiratory, circulatory, and excretory systems, as well as heightened senses, keep them airborne.
Take account of the miraculous feats of navigation performed by birds, as they migrate huge distances with amazing accuracy. Uncover the ways in which birds use visual landmarks, magnetic fields, Sun position, and the position of constellations in their migratory travels. Consider why birds migrate, the diversity of their migration patterns and habits, and the perils of these epic journeys.
Humans have tended to underestimate the intelligence of birds. Examine the structure of the avian brain and the extraordinary forms of intelligence birds show, such as memory, complex spatial mapping, and ingenious strategies in food foraging. Observe the role of instinct in bird behavior, their astonishing use of tools, and how bird behavior is correlated with the seasons.
Track the behavior of birds when they form flocks or colonies. Grasp the diverse benefits of group foraging, and how birds form mixed-species foraging flocks. Investigate group roosting and breeding behavior, and study fossil evidence that suggests some dinosaurs nested just like modern wading birds. Assess why birds form colonies and investigate the advantages and disadvantages of the colonies.
