In 2007, World Migratory Bird Day was celebrated in more than 58 countries and with more than 100 different events all across the planet on 12-13 May. The theme “Migratory birds in a changing climate” helped to focus the world’s attention on the plight migratory birds are facing due to global warming. WMBD activities highlighted the effects that increasing temperatures, altered rainfall and vacillating weather conditions have on migratory birds.
