Rare flight of Antarctic’s Light-mantled Albatross to Tamil Nadu
- Rameswaram and adjoining islets of Gulf of Mannar Marine National Park grabbed attention of international researchers as Asia’s first sighting of Light-mantled Albatross (Phoebetria palpebrate), a species native to the Antarctic seas, was recorded here.
- Fulf of Mannar area is known for unique marine ecosystem.
- The sighting was published in Journal of Threatened Taxa
- It has been regarded as surprising transcontinental tour of the Antarctic seabird.
- This finding directs researchers to look for bird migration away from established routes and sites.
Reason for being sighted in Tamil nadu
- Change in atmospheric pressure can be the reason for Albatross to land on an Indian shore.
- Changes in wind pattern triggered by global warming.
- Birds like albatross use wind and save their energy during flights.
- Slight changes in temperature can cause drastic changes in wind pattern and birds could land in far-away places that are not familiar to them.
