Answer & explanation

Answer: (a) 1 only

Amur Falcons stop over in the Doyang area of Wokha district for about a month each October–November on their long migration to southern Africa. Mass hunting in 2012 gave way to protection by villagers, churches, youth groups and the forest department, which is why the roost now thrives. Satellite tags only record their routes; they do not guide the birds, and the falcons do not stay in India.

  • ✓ 1. After the 2012 slaughter, local communities around Pangti and Doyang turned protectors, enforcing hunting bans; the safe roost is the product of that sustained community effort.
  • ✗ 2. Satellite tagging (from 2013) was used to study the falcons' routes; migratory birds navigate on their own, and tags play no part in guiding them back.
  • ✗ 3. The falcons are passage migrants: they spend about a month in Nagaland and then continue to southern Africa, so they have not become permanent residents.

Remember · Amur Falcon: breeds in Siberia–China–Mongolia, stops over in Nagaland (Pangti, Doyang, Wokha) in Oct–Nov, winters in southern Africa; a community-conservation success after 2012.
