    Few people know bears as intimately as Else Poulsen. She has raised bears, comforted bears, taught bears, learned from bears, had bears communicate their needs to her, and nursed bears back to health. This remarkable book reveals the many insights about bears and their lives that she has gained through her work with them. In the eighties, Poulsen became a zookeeper in Calgary, where she rehabilitated bears in crisis. She has shared in the joy of a polar bear discovering soil under her paws for the first time in twenty years, felt the pride of a cub learning to crack nuts with her molars, and grieved at the horror of captivity for Asian black bears in China.Smiling Bears provides an enlightening and moving portrait of bears in all their richness and complexity and of Poulsen's exhilarating work with them.

    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.

    When one of his release sites was raided by a golden eagle, he managed to save a peregrine chick, and decided to make an improbable two-thousand-mile trip with the surviving young falcon, Dolly. From the Canadian border to the Gulf of Mexico, following the autumnal migration of waterfowl, O'Brien taught her to hunt as a wild falcon would, in the hopes of releasing her into the natural world. The Rites of Autumn is the riveting account of their incredible journey. (51/2 X 81/4, 208 pages, map)

    What took place as an astonished public came upon these snowballs -- each weighing about a ton -- is captured in spontaneous and evocative pictures taken by photographers working around the clock.Here, then, is the story of Goldsworthy's largest ephemeral work to date. Made in one century (the 20th) and unwrapped to melt very slowly in the next, this is four-dimensional sculpture in which the lifespan and history of the snowballs are as important as their appearance at any moment. As Judith Collins explains in her introduction, and Goldsworthy in his diaries, this is a natural progression from his previous work with snow. Goldsworthy presents a unique confrontation between the wilderness and the city -- snowballs made in the Scottish winter brought to the streets of London in the summertime.

    Drawing deep from personal experience, cutting-edge science, and colorful history, he spins captivating stories about the birds in our midst and reveals the startlingly intimate coexistence of birds and humans.
