Wetland habitats in Britain and other parts of western Europe have been severely depleted during the latter part of the Holocene owing principally to drainage and land reclamation. Changes in the distribution of a number of wetland bird species can be gauged from archaeological and geological site records of larger birds, whose remains are generally better preserved. Key species are discussed here, including a heron Nycticorax fenensis and a crane Grus primigenia, two extinct species named on possibly uncertain fossil evidence.
