The Gialova Lagoon in the region of Messinia in the southwest Peloponnese isn't the country's largest wetland, but it might just be the most important one in Greece and the Balkans, as it constitutes Europe’s southernmost migratory station. Migratory birds traveling back and forth between Africa and Europe stop at this site, resting and feeding before or after their long flight over the Sahara and the Mediterranean Sea. Some birds stay for just a few hours before resuming their journeys north or south. Others rest up for a few days, while some species make Gialova their final destination. Herons, glossy ibises, ducks, flamingos and shorebirds find shelter here;seen from afar the flocks comprise an impressive mosaic.
