What is a flyway?
- A flyway is a flight path used in bird migration. Flyways generally span over continents and often oceans.
- The migration routes often follow a north-south axis covering more than 30 countries.
- They are seasonal in the sense that they move to milder climates at lower latitudes during their non-breeding season.
- Birldlife International has designated migratory routes as 8 flyways in the world.
Flyways in India :
- India is an integral part of 3 flyways.About 370 species of migratory birds visit the Indian subcontinent mostly the wetlands of India as staging sites.
1. Central Asian Flyway
- The Central Asian Flyway (CAF) covers a large continental area of Eurasia between the Arctic and Indian Oceans and the associated island chains.
- The Flyway comprises several important migration routes of waterbirds, most of which extend 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 the British Indian Ocean Territory.
2. East Asian-Australasian Flyway
- Encompasses 22 countries extending from Arctic Circle, through East and South-east Asia including eastern India and Andaman and Nicobar Islands., to Australia and New Zealand.
- About 178 waterbird species use this migration path every year.
3. Asian East African Flyway
- It is a group of well-established routes by which many species of birds migrate annually between mid-Palearctic breeding grounds in Asia and non-breeding sites in eastern and southern Africa.
