Explanation
Each October–November, Amur falcons breeding in Mongolia, Siberia and northern China stop over at the Doyang reservoir in Nagaland on their way to southern Africa. After mass hunting was exposed in 2012, villages such as Pangti turned protectors, and the birds' return showcases community conservation, so statement 1 is correct. Satellite tags only track the birds and do not guide them (2), and the falcons are passage migrants, not permanent residents (3).
