The Nanjarayan Tank, a bio-diversity hotspot, has just been announced as the 17th bird sanctuary of Tamil Nadu.
The Nanjarayan Tank also known as Sarkar Periyapalayam Reservoir, is located on the outskirts of Tirupur city near Koolipalayam, about 60 kilometres from Coimbatore.
The tank, built by the then local King Nanjarayan as a source for irrigation, is a haven for migratory birds.
