For an authentic scientific study of their behaviour, tigers in the Sunderbans, the world's only mangrove eco-system which has big cats, will be fitted with radio collars, forest officials said.
"Last week a tigress which had strayed into Gosaba area in South 24 Parganas district was fitted with a radio collar. We have to radio collar a few more tigers which will provide information about their behaviour in Sunderbans," Sunderban Biosphere Reserve (SBR) director Pradeep Vyas told PTI.
There was no scientific study on the behaviour of the big cats in the Sunderbans and all information was based solely on observation, he said.
"So, an authentic scientific study is needed and radio collars will provide us exact information about the behaviour of tigers," Vyas said.
It was found that it was the same tigress which had entered the locality for a second time in the past six months.
Experts from the Wildlife Institute of India had last week fitted the tigress with a radio collar after it was tranquilised.
Vyas said as per signals received from the radio collar, the tigress was roaming within a three-km area at Chorkhali in Netidhopani where it was released.
