The Sun Village is well placed for the rice paddy's opposite the Marinha Dourada, Baga Hill, Baga Fields, Arpora Woods etc etc.
Try the Beira Mar hotel, a well known birders hang out, for an evening beer and to find a knowledgeable taxi driver/guide.Lots of the bird tours use it as a base. Not the best hotel but good bird watching and craic from their rear terrace.
We are off imminently and I'm looking forward to seeing Goa just after the rainy season. I have only been in February when everything was pretty dry.
Looking forward to the abundant Kingfishers too, not all will have feathers on either !!!!!!
