Which of the following statements with regard to the arrival of Amur Falcons at Doyang Lake in Nagaland each year from Mongolia is/are correct ? 1. It showcases how sustained local conservation efforts can contribute to the arrival and protection of international migratory birds. 2. It reflects the global success of advanced tracking technologies that guide migratory birds back to their stopover sites. 3. It confirms that Amur Falcons have adapted to permanent residency in India due to favourable habitat changes.

Amur Falcons migrate annually from breeding grounds in southeastern Siberia/northern China/Mongolia to Africa, with Doyang Lake in Nagaland being a major stopover roosting site. Statement 1 is correct: the Pangti village community in Nagaland has transformed from hunters to protectors of Amur Falcons, demonstrating how sustained local conservation efforts protect international migratory birds. Statement 2 is incorrect: migratory birds navigate using their innate biological mechanisms (sun, stars, magnetic field), not tracking technologies — tracking technologies monitor birds but do not guide them. Statement 3 is incorrect: Amur Falcons are migratory, only stopping over in India for a few weeks before continuing to Africa; they have not adapted to permanent residency.
