location: Chidambaram in Cuddalore District, Tamil Nadu, in South India
The area is about 1100 Hectare and is separated from the sea by a sand bar.
The Pichavaram mangrove biotope, consisting of rare species like Avicennia and Rhizophora presents a special attraction, with its peculiar topography and environmental condition. It supports the existence of many rare varieties of economically important shell and finfishes.
The Pichavaram mangroves attract an appreciable bird population of residents, local migrants and true migrants. Amongst others, one can view birds like snipes, cormorants, egrets, storks, herons, spoonbills and pelicans. At the mangroves, so far, 177 species of birds belonging to 15 orders and 41 families have been recorded. The season for birds is from September to April every year. Peak population of birds could be seen from November to January. This is due to high productive nature (in terms of prey organisms) of the ecosystem and coincidence of the time of arrival of true migrants from foreign countries and local migrants from their breeding grounds across India. The availability of different habitat types such as channels, creeks, gullies, mud flats and sand flats and adjacent sea shore offers ideal habitat for difference species of birds and animals.
