A flyway is a geographical region within which a single or a group of migratory species completes its annual cycle – breeding, moulting, staging and non-breeding. Central Asian Flyway (CAF) covers a large area of Eurasia between the Arctic and Indian Oceans. It is one of the nine most important flyways of migratory birds around the world.
Including India, there are 30 countries under the Central Asian Flyway. It extends from the northernmost breeding grounds in the Russian Federation (Siberia) to the southernmost non-breeding (wintering) grounds in West and South Asia, the Maldives and British Indian Ocean Territory.
