Populations of turtle dove, nightingale, cuckoo, wood warbler and other long-distance migratory birds are declining so rapidly in the UK and Europe that the RSPB, BirdLife International and BirdLife partners from other European and African countries will be lobbying this week for their plight to be addressed at a conservation gathering focused on conserving the world’s migratory species. The decline of these birds, which are shared between Europe, the Middle East and Africa, is so severe that conservationists believe the only way to save them is through concerted international action.
