In 2012 the World Migratory Bird Day theme focused on the cultural relationship between birds and people. Throughout time and across cultures humans have relied on birds, be it to supply food, to deliver messages, or to serve as symbols of power and prestige. Amazingly more than 250 events were registered in 81 countries around the world on May 12th and 13th, showing an increase of 25 % from 2011 and an expansion of three-fold since its inception in 2006!
