Impatient to get on to the boat for a closer look at flamingos at the newly opened Airoli sanctuary? You'll have to wait for at least a month, since the most important part of the deal – the boat – is yet to arrive. "After the larger boat arrives next week, we will complete the process of registration. By the end of the month, visitors should be able to take a ride to see the flamingos," said N Vasudevan, Chief Conservator of Forest, Mangroves Cell.
