Gyrfalcon [PDF ebook] 

WINNER OF THE WILDLIFE SOCIETY’S ‘BEST SCIENCE BOOK 2006′ AWARDThis book is the first monograph on one of the most beautiful and admired birds in the world. The Gyrfalcon is the world’s largest and most powerful falcon — a truly awe-inspiring bird which inhabits the ferociously inhospitable Arctic taiga, from Greenland and Iceland right across Siberia and northern Canada. Its plumage varies from a dark mottled grey to pure white — the white birds in particular are coveted by birders and falconers. Like other titles in the series, it covers all aspects of the species’ biology, taxonomy, distribution, status and historical associations with mankind. The result is an exhaustively researched and enthrallingly readable biography of a spectacular bird, illustrated throughout with photographs and line drawings.
