There is (or at least was) a Delhi e-mail group, though I don't remember the access details. There is (or again at least was) a fairly bird-productive stretch of river down near Noida.
Personally, I think Delhi is close to being one of the worst places on earth, just about beaten by Karachi, which truly is grim - think Delhi with worst squalor, worst weather (especially pre-monsoon) and with a significant safety risk.
