Bhubaneswar: Authorities are on their toes to keep poachers away from Chilika lake as lakhs of migratory birds have started arriving at the Asia's largest brackish water lake.

Chilika divisional forest officer Bikash Ranjan Das said more than two lakh birds have already arrived to spend the winter in the famous lagoon. He said that his department was doing everything possible to play perfect host to the winged guests and ensure their safety.

"We have set up 19 anti-poaching camps to keep an eye on bird hunters," said Das, adding that stepped up vigil was already paying dividends. No cases of poaching have been reported so far from the lake this season.

Ten anti-poaching camps have been set up at Tangi, while vigil has also been stepped up at Mangalajodi and Bhushandpur. The forest department has sought to strengthen the lake's security by deploying around 10 country boats and two powerboats to patrol its waters. Police assistance will also be sought.

Last year, the authorities had set up 18 anti-poaching camps in the lake. However, several cases of poaching were still reported. In November last year, forest officials had caught four poachers from various parts of the lake.

Tangi in Khurda district is considered one of the most poaching-prone areas. Sorana and Mangalajodi are also counted sensitive areas.

On the other hand, steps are afoot to make places such as Mangalajodi attractive for visitors who flock to the area in large numbers to watch birds. An upgraded interpretation centre will shortly be opened at Mangalajodi. The watchtower in the area will also be renovated by spending Rs 23.50 lakh.

During the last census in January this year, more than nine lakh birds belonging to 176 species had been counted in the lake. Wildlife authorities hope the number will go up in the next census.
