A pilotless aircraft will keep a vigil on the Kaziranga National Park where animals are in disarray after a large part of the world famous sanctuary was flooded, and also to help deal with poaching.

Secretary of the National Tiger Conservation Authority, Rajesh Gopal, said here on Tuesday the step has been taken after a team of the authority, which would fund the project, conducted an aerial survey last week and found that the situation was critical with nearly the entire park flooded.
