Oriental Pratincole (Glareola maldivarum) is a truly remarkable migrant that breeds in the Indian Subcontinent and Southeast Asia and migrates all the way to Australia for the winter!
This phenomenon was discovered only in 2019 when an Oriental Pratincole that was Satellite tagged in Australia flew through Thailand and Orissa to finally settle down and breed in northern Karnataka. Some birds appear to spend the winter in India as well. Other species that make migratory flights from India to Australia are White-throated Needletail and Curlew Sandpiper.
