Chennai: Bird watchers are thrilled with the recent sightings of ruddy shell duck at the Pallikarnai marsh. Though the bird is found in large wetlands, rivers with mud flats, their movement is mostly restricted to north India and their sightings displays the biodiversity of Pallikarnai, said K.V.R.K Thirunaranan, founder, The Nature Trust.
They are usually in found in large congregation on lakes and reservoirs across north India but it is rare to sight them in the swamps of south India. There have been several earlier recordings of these birds and after very long time, they are now sighted in the marsh, he said.

The recent intervention by the state government to restore the Pallikarnai marshland has started yielding results and the sighting of migratory birds has improved in the past few months.
Rare birds like Comb Duck was recently spotted and to spot comb duck one earlier had to go all the way to Kunthankulam bird sanctuary in Tirunelveli and last month even flamingoes frequented the marsh, said N. Balaji, an avid bird watcher and a software professional.
The real estate pressure and urbanisation has eaten in to the buffer areas of the marsh, but still Pallikarnai proves to be an ideal habitat for migratory and wading birds.
