Kalai Lake is a sweet-water lake in Valsad district. During winter many ducks arrived here. When there is prey there come the hunters. Here you can see Peregrine Falcon, Western Marsh Harrier, Osprey etc. made this place their hunting ground. We are lucky to see them in action. First, they separate single duck from a group. Then attacked prey within water. Once it killed, they pick it up and leave the place. Here both raptors, Peregrine Falcon and Western Marsh Harrier try their best to get prey. But in the end, the Peregrine Falcone won the chase and got the trophy.
