This is geeky OCD at its finest: a meticulous Indian birding guide. It has lovely pictures, extensive trip notes and even some on historical notes on bird-watching in India. (A fascinating example: Ustad Mansur, a painter employed by Emperor Jehangir, painted the Dodo.)
Finally, a country that has "13% of the world's bird species" gets a birding guide it deserves.
Update: Ludwig pointed me to another very cool bird site, India Birds. (The site resizes the browser window and requires QT plug-in to play birdsongs.)
