دانلود کتاب RSPB Seabirds

Seabirds are the living links between land, air and sea. They enjoy a freedom that even humans, with all our technological assistance, can barely imagine. Many species travel mind-boggling distances across the length and breadth of our planet before returning to land to breed in large, deafening and confusingly crowded colonies. Yet within this commotion each mated pair forms a bond of extreme closeness and tenderness that survives separation each winter and may persist for decades.The long and geologically varied coastline of the British Isles provides homes for internationally important numbers of breeding seabirds. Visiting their colonies is always unforgettable, whether they are cliff-faces packed with Guillemots, islands white-capped by clustered Gannets on their nests, flat beaches crowded with screaming Arctic Terns or seaside rooftops overlaid with a second townscape of nesting gulls. The changing fortunes of these seabird cities reveal to us the health of the vast, unseen but incredibly rich marine world that surrounds us.RSPB Seabirds showcases some of our most exciting and enigmatic bird species as vital and living components of one of our greatest natural assets: our coastline. The author presents detailed biographies of all the seabird species that breed in and around the British Isles, and also looks at the many species that breed elsewhere but which, regularly or occasionally, visit British waters. Every page of this sumptuous book features beautiful photographs of wild seabirds engaged in their daily work of hunting, traveling, protecting themselves and their territories, and courting and raising a family.
