Thepotential responses of birds to climate change have come increasinglyto the fore, and are of particular interest to the ornithologicalcommunity. Are birds sensitive to climate change and how will theyreact to a world of global warming? These are the key issues to beexplored in this book, with particular reference to Western Palearcticbirds. Climate changes that have affected the region in the last two millionyears will be explored, drawing on published data on fossil birds. Amajor part of the book will be devoted to the distribution of WesternPalearctic birds in relation to bioclimate.
