MIGRATION

        GLOBETROTTERS
        Waders and wildfowl are amazing travellers but so are some
        small, familiar birds. For example, Swallows from the United
        Kingdom travel to the far south of Africa in winter.Barnacle
        Geese fly north in spring to breed around the Arctic.Such
        birds that breed in the far north remain in the south till late
        in May,when the Arctic snows begin to melt.The map
        below shows three examples of long-distance migration.

                                          Fieldfares move south and west in
                                          winter to avoid cold weather. In

                                          cold or snow, but they return
                                          as soon as conditions improve.
