Asian Open Bill or Asian Open Billed Stork

We first saw these birds at the Ranganathittu Bird Sanctuary, but on my recent trip to Tamilnadu, we saw this one in a rice field, somewhere between Mayiladudurai (Mayavaram) and Tarangambadi (Tranquebar)....



Would I be right in thinking that its the Cauvery which draws them? What do you think?

P.S. Posts on the blog will be erratic for a while because of some major renovation work in our house which has restricted my access to the computer. I will, however, be posting regular updates as well as photographs on Facebook, Twitter, and Instagram. Please follow me there to see what I am up to. Besides, I am off on another trip soon, so stay tuned for a lot more photos!!!
