An Indian spot-billed duck (Anas poecilorhyncha) with pale plumage was sighted at Manickapuram tank in Tiruppur district recently.
Birders who observed the duck said the individual got the pale feathers due to leucism, a condition that prevents melanin and other pigments from being deposited in its feathers.
S. Nandagopal, a member of the Nature Society of Tirupur (NST), spotted the rare leucistic duck when he went to Manickapuram tank near Mudalipalayam SIDCO for birding on September 16.
