I think the calf was hit by a truck or bus. That explains the aggressive behaviour displayed by the mom. It happens very often in that road. I would be happy if that road had barricades (you find all kinds of barricades raised by the police on the road displaying advertisements of Nalli saris and others) in cities like Mysore, Bangalore etc where it is not required.

I won't mind if the road passing through Bandipur and Mudumalai is not well maintained. Atleast, that would stop people from driving fast.

People need to be educated about throwing rubbish and honking. The forest guard can tell people driving past the check gate.
