Went to Ranganathittu Bird Sanctuary in mid september 2013 for about an hour in the evening, as an unscheduled detour from the bangalore - mysore highway. This place was a pleasant surprise - lush greenery, beautiful birds and majestic crocodiles, well maintained gardens and a wonderful boat ride on the lake. Very affordable - i paid all of one hundred and thirty rupees for entry, boat ride and car parking. The boat guide explained that it was not the normal migratory season in september and there was only one species, the oriental white ibis, at the sanctuary. We saw several hundredbirds of the species and some really huge crocodiles basking on rocks in the middle of the lake. Loved the place - a must visit.
