At the 13th Session of the Conference of the Parties (COP13) to the Convention on Migratory Species (CMS) held in Gandhinagar in February this year, Costa Rica, supported by Argentina, Bolivia, Paraguay, Peru and Uruguay, successfully proposed the listing of the Jaguar (Panthera onca) on both Appendices of the Convention.  Therefore, CMS welcomes the designation of 29 November as International Jaguar Day and the efforts being made to establish a coordinated regional mechanism to promote Jaguar conservation and create a network of connected sites across Central and South America.
