Dr. Doug Wechsler, a wildlife biologist, ornithologist, and photographer, has written this wonderful series on birds of prey. Each book includes an introduction to a bird: its size, color, and habitat; its hunting, eating, and migration habits; how and where it builds its nest, and its survival strategies. Clear, accessible, and often humorous text is combined with spectacular photography from VIREO, the Visual Resources for Ornithology, and The Academy of Natural Sciences of Philadelphia, to create books that will delight and inform your students.There's no doubt about it: vultures are unsavory. As Doug Wechsler writes, "Thinking about what vultures eat is enough to make you want to throw up." This humorous and informative book presents a balanced picture of these birds that, despite their lack of social graces, perform a vital role in their ecosystem by acting as garbage collectors.
