"Three Amur Falcon tagged in 2013 covered the distance of 6000 km from Nagaland to Mongolia in five days 10 hours to return last year," Javadekar told reporters here.
"Carrying a five gramme solar powered geo tag, the birds reached South Africa from Nagaland in a continuous flying mode," the minister said.
It is being planned to do the same thing again and tag more of the migratory birds at three or four roosting sites in Pangti and other villages of Nagaland, he said.
Javadekar said, "The birds will be named as per the villages as Amur Falcon conservation is a people's movement involving locals, NGOs, church and the forest department. People who used to kill these birds are now committed to its conservation".
