Discovering Birds
de Prof Paul Lawrence Farber(Ed. Johns Hopkins University Press) Isbn : 0801855373
19.49 €
In Discovering Birds, Paul Lawrence Farber rejects the view that eighteenth-century natural history disappeared with the rise of nineteenth-century biology. In this penetrating case study of the history of ornithology, Farber demonstrates interesting continuities: as natural history evolved into individual sciences (botany, geology, and zoology) and specialties (entomology and ichthyology), the study of birds emerged as a distinct scientific discipline that remained observational and taxonomic. Ornithologists continued to see one of their primary tasks as classification, and they found no need to alter their approach. Their efforts were greatly aided at the end of the eighteenth century as colonization and exploration brought new dataa plethora of exotic and previously unknown birds. By th...

The Lung-Air Sac System of Birds: Development, Structure And Function
de John N. Maina(Ed. Springer-Verlag Berlin and Heidelberg GmbH Co. K) Isbn : 3540255958
100.05 €
In biology, few organs have been as elusive as the lung-air sac system of birds. Considerable progress has recently been made to fill the gaps in the knowledge. While summarizing and building on earlier observations and ideas, this book provides cutting-edge details on the development, structure, function, and the evolutionary design of the avian respiratory system. Outlining the mechanisms and principles through which biological complexity and functional novelty have been crafted in a unique gas exchanger, this account will provoke further inquiries on the many still uncertain issues. The specific goal here was to highlight the uniqueness of the design of the avian respiratory system and the factors that obligated it.

The Grail Bird: Hot on the Trail of the Ivory-billed Woodpecker
de Tim Gallagher(Ed. Houghton Mifflin Harcourt) Isbn : 0618456937
23.76 €
In April 2005, a startling announcement burst into the national and international news--a bird long feared extinct, a bird so distinctive that it has been referred to as the "Lord God bird," had been rediscovered. Not only had various noted ornithologists sighted the bird, but one researcher had also managed to get a few seconds on videotape of the bird in flight. The ivory-billed woodpecker, the largest of its kind in North America, was back from the dead. Gallagher, currently editor in chief of Cornell University Laboratory of Ornithology's journal Living Bird, was one of the first two qualified observers to see the bird in February 2004. This set off a massive, organized search, and with several other sightings, the scientists felt it was safe to report that the ivory-bill was not extin...

The Life History of a Texas Birdwatcher: Connie Hagar of Rockport
de Karen Harden McCracken(Ed. Texas A M University Press) Isbn : 1585441449
28.46 €
In any other context, saying that someone was«for the birds»would hardly be polite. But applied to Connie Hagar, it would be high praise. The diminutive birdwatcher nicknamed Connie was reared as Martha Conger Neblett in early twentieth-century Texas, where she led a genteel life of tea parties and music lessons. But at middle age she became fascinated with birds and resolved to learn everything she could about them. In 1935, she and her husband, Jack, moved to Rockport, on the Coastal Bend of...

Evolutionary Ecology Across Three Trophic Levels: Goldenrods, Gallmakers, and Natural Enemies
de Warren G. Abrahamson, Arthur E. Weis(Ed. Princeton University Press) Isbn : 0691037337
93.32 €
In a work that will interest researchers in ecology, genetics, botany, entomology, and parasitology, Warren Abrahamson and Arthur Weis present the results of more than twenty-five years of studying plant-insect interactions. Their study centers on the ecology and evolution of interactions among a host plant, the parasitic insect that attacks it, and the suite of insects and birds that are the natural enemies of the parasite. Because this system provides a model that can be subjected to experimental manipulations, it has allowed the authors to address specific theories and concepts that have guided biological research for more than two decades and to engage general problems in evolutionary biology.The specific subjects of research are the host plant goldenrod (Solidago), the parasitic insec...

And this dedicated population continues to grow each year.Now, National Geographic offers novice to advanced birders and photographers a sturdy, easy-to-carry guide packed with the information they will need to take their best wild bird photographs. Author Rulon Simmons, a 30-year birder and award-winning photographer, joins Bates Littlehales, a 40-year National Geographic photographer specializing in birds, to offer specifics on finding and photographing birds, whether in the backyard or in the nation's stunning national parks. Includes comprehensive information with full-color images on the right films and lenses to use ; ...

Sibling Species of Titmice in the Parus Inornatus Complex (Avesâ€'Paridae)
de Carla Cicero(Ed. University of California Press) Isbn : 0520098080
30.66 €
In a comprehensive investigation of macrogeographic variation in the Plain Titmouse (Parus inornatus) complex in western North America, the author assessed population-level patterns of differentiation in morphometric, colorimetric, allozymic, mtDNA, and vocal characters. These suites of traits showed broad geographic concordance, distinguishing Pacific slope from interior populations. These two groups of populations are treated as sibling species.

Life List: A Birder's Spiritual Awakening
de Chris Dunford(Ed. Editions Novalis) Isbn : 2895077134
16.4 €
In 1998, Chris Dunford flew from California to Winnipeg. He then took the train north to Churchill and Hudson's Bay. He spent a week adding new sightings to his "life list" of birds. During the course of that week, he encountered a wide array of birds from Canada's North and discovered that he was coming to terms with a whole series of much deeper questions about his place inthe created world and his relationship to God. This is a unique book about birding that this as much about spirituality as it is about the fanatical interest that some people have in birds.
