In this newly revised edition, chapters have been rewritten to accommodate the impact of computer technology and the Internet, not only on the acquisition and analysis of data, but also on its organization and presentation. Alternatives to the use of radiation have been expanded, and figures and illustrations have been redrawn to reflect changes in laboratory equipment and procedures.

    

    Since that time he has answered thousands of questions about birds, both at his store and while walking down the aisles of the supermarket. The questions have ranged from inquiries about individual species ("Are flamingos really real?") to what and when to feed birds ("Should I bring in my feeders for the summer?") to the down-and-dirty specifics of backyard birding ("Why are the birds dropping poop in my pool?"). Answering the questions has been easy; keeping a straight face has been hard.Why Don't Woodpeckers Get Headaches? is the solution for the beginning birder who already has a book that explains the slight variation between Common Ground-Doves and Ruddy Ground-Doves but who is really much more interested in why birds sing at 4:30 A.M. instead of 7:00 A.M., or whether it's okay to feed bread to birds, or how birds rediscover your feeders so quickly when you've just filled them after a long vacation. Or, for that matter, whether flamingos are really real.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean. A leading advocate for the responsible collection and care of wild-caught specimens, Fenner starts with the basics -- "What is a fish?" -- and proceeds to give the reader the scientific background and expert-level secrets to being a smarter consumer, better steward, and more successful marine aquarium keeper.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.
