How do we find out about the migration routes and winter quarters of these birds; how do the birds know the right time to leave on migration, what their destination is, and how to find their route; and how do they manage to survive the journey of thousands of kilometres and the crossing of deserts and oceans? These, and many other questions, have occupied natural scientists for centuries. arl von Linné (1707-1778), in its neck, provided an indication of 120 million ringed birds), we have his Migrationies Avium pub- where it had spent the winter, as did reasonably good information on the Clished in 1757, still assumed the first ringing of White Storks and migration behaviour of many species that migrant birds hibernated at Woodcocks in the 19th century with (see pp. 16–19). the bottom of water bodies.
