World Migratory Bird Day 2011 observed 14-15 May in over 50 countries
The theme for World Migratory Bird Day 2011, celebrated around the world on 14-15 May, is ' Land use changes from a bird's-eye view ' and it highlights the negative effects human activities are having on migratory birds, their habitats and the planet's natural environment. World Migratory Bird Day is being organized by the Convention on Migratory Species (CMS) and the African-Eurasian Migratory Waterbird Agreement (AEWA) - two intergovernmental wildlife treaties administered by the UN Environment Programme (UNEP). BirdLife International, Wetlands International and the Secretariat of the Partnership for the East Asian - Australasian Flyway (EAAFP) are also main partners of the global campaign.
