About World Migratory Bird Day

• It is an annual awareness-raising campaign highlighting the need for the conservation of migratory birds and their habitats. 
• It has a global outreach and is an effective tool to help raise global awareness of the threats faced by migratory birds, their ecological importance, and the need for international cooperation to conserve them.

The campaign is organized by two international wildlife treaties administered by the United Nations Environment Programme (UNEP).

• Convention on the Conservation of Migratory Species of Wild Animals (CMS)
• African-Eurasian Migratory Waterbird Agreement (AEWA) – together with Environment for the Americas (EFTA).

About Convention on the Conservation of Migratory Species of Wild Animals (CMS)

• It is an environmental treaty under the aegis of the United Nations Environment Programme that provides a global platform for the conservation and sustainable use of migratory animals and their habitats.
• Also referred to as the Bonn Convention, it provides a global platform for the conservation and sustainable use of migratory animals and their habitats and brings together the States through which migratory animals pass, the Range States, and lays the legal foundation for internationally coordinated conservation measures throughout a migratory range.
• Classification of species: Under this convention, migratory species threatened with extinction are listed on Appendix I and Parties strive towards strictly protecting these animals, conserving or restoring the places where they live, mitigating obstacles to migration and controlling other factors that might endanger them.
• Migratory species that need or would significantly benefit from international co-operation are listed in Appendix II of the Convention.
• CMS is the only global and UN-based intergovernmental organization established exclusively for conservation and management of terrestrial, aquatic and avian migratory species throughout their range.
