Just east of Old Goa, the lily-covered Carambolin Lake has an enormous amount of waterfowl, many Egrets and Heron, Bronze-Winged, Pheasant-Tailed Jacana and thousands of exotic species such as Comb Duck and Cotton Pygmy-Goose.
Close to Carambolim is the Ciba-Geigy Chemical-Works, which
has created a pleasant nature reserve. Here one may sight Open-billed
Storks, Purple and Grey Heron, Little Cormorant and Marsh Harriers.
