“Birds Connect Our World” was the theme for WMBD 2020. Connectivity is essential for migratory species, and important for a wide variety of ecological functions. It describes the natural and necessary movement of species and the flow of natural processes that sustain life on Earth. With 1 million species facing the risk of extinction within our generation, connectivity has become a central topic for biodiversity and sustainability. Migratory species move across the globe, running, swimming, flying, connecting countries, people and continents through their migration routes. This migration can only be accomplished when animals are able to access the different sites and habitats that they rely upon along their pathways.
