The volumes in the Birds of Ontario series summarize life history requirements of bird species that are normally part of the ecology of Ontario. The first volume dealt with waterfowl through cranes; this volume deals with shorebirds through woodpeckers and completes the treatment of the nonpasserines. Information on habitat, limiting factors, and status are dealt with for the three main bird seasons: breeding, migration, and winter. It is an essential reference for biologists, planners, environmental consultants, and other resource professionals involved in environmental issues and management pertaining to birds. It is also a valuable reference for serious birders.

Описание:
Rising from sandbars on the Platte River with clarion calls, the sandhill crane (Grus canadensis) feels the urgency of spring migration. Elegant, noble, and spiritual, the sandhill crane is one of the most ancient of all birds. More than a half-million strong, flying in squadrons, these majestic creatures point northward to their Arctic and sub-Arctic breeding ranges. Theirs is an epic story of endurance through the ages.
With 153 stunning color photographs, On Ancient Wings presents sandhill cranes in their wild but increasingly compromised habitats today. Over the course of five years, Michael Forsberg documented the tall gray birds in habitats ranging from the Alaskan tundra, to the arid High Plains, from Cuban nature preserves to suburban backyards. With an eye for beauty and an uncommon persistence, the author documents the cranes’ challenges to adapt and survive in a rapidly changing natural world. Forsberg argues that humankind, for its own sake, should secure the cranes’ place in the future. On Ancient Wings intertwines the lives of cranes, people, and their common places to tell an ancient story at a time when sandhill cranes and their wetland and grassland habitats face daunting prospects.
Описание: The vast literature on the history of birds is continually growing, but rarely has this information been compiled so that it is readily available in one reference work. Birds of Ontario is such a work, providing a comprehensive summary of the life history requirements of bird species in the province.
