The three birds, Amur Falcon, Naga and Pangti, were tagged by researchers in Nagaland on 6, November. These birds were tagged with an antenna and solar panel on their back, which weighs five grams.

Out of the three birds, two were tracked flying over the Arabian Sea by the team of scientists. Scientists said that these birds ware tracked after covering long route from Bangladesh, the Bay of Bengal, Andhra Pradesh, Karnataka and Maharashtra towards their final destination in South Africa.

The third falcon was tracked in, Wokha, flying over the Bay of Bengal. M. Lokeswara Rao, Principal Chief Conservator of Forests and head of the Forest Force, Nagaland, said that they started the tracking process just after these birds were released.

The arrival of Amur falcons in Nagaland is still a mystery for the scientist. They are confused on how these birds migrated from Mongolia to South Africa, which is such a long distance.

Scientists in Hungary had noted the route of all the three falcons by tracking the satellite tagged on their back. They had done this by filtering the satellite data with the help of a dedicated website. Out of the three falcons, Naga was the male falcon and Amur and Pangti were females.
