Some extraordinary stories. Nice pictures. ( ) I love it when even an older book can teach me something! Even though I've read other, newer books on bird intelligence and behavior, I didn't know that some types of jays and crows have nest helpers. These are usually offspring from previous years who come back to their parents. They are there primarily to learn how to select nest sites, build nests, raise chicks, find food and other parental duties. Eventually they help feed the nestlings. Some birds do this for 3-4 years before setting up their own households. Studies have shown that birds who do this are better and more successful parents than birds who don't. A note about the photography - it's great to see film again. It has a particular quality of contrast, grain and color separation that digital, for all it's precision and high-resolution just doesn't have. A lot of the shots were taken in low light and have slower shutter speeds and so have some motion-blur. Just lovely. An absolutely beautiful book! The photographs alone make it worth picking this one up. Candace Savage takes the reader through the latest research on corvids -- crows, ravens, magpies and jays. She takes us through what is known and not known about how these birds think. These birds are so fascinating -- they use tools, they form complex social relationships and seem to have memory and the ability to reason. As the author says, calling someone a bird brain may be a compliment. A beautiful photographic essay text that tells of the intelligence of birds in the corvid or crow family. Stunning close-up photographs of various corvids fill the pages and the author tells the story of corvids with supporting research. The text has a conversational tone and at times is humorous. The author titles one of the chapters "Bread and Butter Issues" and proceeds to discuss the many ways corvids obtain food. This was a great book to have in the classroom for a study of bird identification and animal intelligence. I personally will never look at a crow the same as I used to just knowing how intelligent they really are after reading this book. A thoroughly engaging look at members of the crow/jay families of birds. There are enough references to scientific studies to give credence to the author's suppositions, but not so much to bog it down with scientific jargon. Oh, and the photographs are gorgeous. Though I've been birding for half a century, I came across some information with which I was unfamiliar. Nice read. sem resenhas | adicionar uma resenha
Internationally celebrated nature writer Candace Savage presents the Corvid family-- surprisingly bright, brassy, and colorful birds--in a remarkable collection of full-color, close-up photographs by some of the world's best wildlife photographers. Birds have long been viewed as the archetypal featherbrains--beautiful but dumb. But according to naturalist Candace Savage, "bird brain," as a pejorative expression, should be rendered obsolete by new research on the family of corvids: crows and their close relations. The ancients who regarded these remarkable birds as oracles, bringers of wisdom, or agents of vengeance were on the right track, for corvids appear to have powers of abstraction, memory, and creativity that put them on a par with many mammals, even higher primates. Bird Brains presents these bright, brassy, and surprisingly colorful birds in a remarkable collection of full-color, close-up photographs by some two dozen of the world's best wildlife photographers. Savage's lively, authoritative text describes the life and behavior of sixteen representative corvid species that inhabit North America and Europe. Drawing on recent research, she describes birds that recognize each other as individuals, call one another by "name," remember and relocate thousands of hidden food caches, engage in true teamwork and purposeful play, and generally exhibit an extraordinary degree of sophistication.
