- The annual migration of birds from the Arctic to the Gulf of Mannar Marine Biosphere Reserve, has begun with an enormous flock seen swarming the Manoli Islands inside the park.
- The seasonal ritual of migration occurs every year over the Central Asian Flyway (CAF), comprising 29 countries including Iraq, Kuwait, Qatar, Kyrgyzstan, Nepal, India, Bhutan, Myanmar and Maldives.
- The Arctic birds begin their journey through India from the Bhitarkanika National Park, Odisha, and fly over to Kanniyakumari, the southern-most tip of coastal Tamil Nadu. The flocks again return in March on their way back.
