Explanation
  • Amur Falcons are long distance migratory raptors that travel annually from their breeding grounds in East Asia to wintering grounds in Southern Africa.
  • Doyang Lake in Nagaland serves as a crucial stopover site for millions of these birds, earning the state the title of Falcon Capital of the World.
  • A massive community led conservation effort successfully ended the local practice of hunting these birds, transforming the villagers into dedicated protectors.
Statement Analysis
  • Statement 1. It showcases how sustained local conservation efforts can contribute to the arrival and protection of international migratory birds: Correct. The transition of local communities around Doyang Lake from hunting to protecting the falcons is a globally recognized conservation success.
  • Statement 2. It reflects the global success of advanced tracking technologies that guide migratory birds back to their stopover sites: Incorrect. Advanced tracking technologies like satellite tags are used by researchers to map and study migration routes, but they do not guide the birds, which rely on natural navigation.
  • Statement 3. It confirms that Amur Falcons have adapted to permanent residency in India due to favourable habitat changes: Incorrect. Amur Falcons are strictly migratory and only visit India temporarily during their transit to Africa, not as permanent residents.
