The Okhla Bird Sanctuary, which has been in the news since the beginning of the year due to a plea for restricting construction activity in the surrounding areas, has started receiving winter migratory ducks much earlier than anticipated.

According to environmentalist and ecologist T.K. Roy, who has been monitoring the movement of migratory birds across the country, smaller flocks of winter migratory birds have arrived at the bird sanctuary this year.

Most of them have descended right at the middle of the wetland habitat, where disturbance from the surroundings is minimal.

Dr. Roy said the birds that have already arrived include the northern shoveler, common pochard, tufted duck, Eurasian wigeon, common teal and Gadwall.

Northern shoveler: This migratory duck breeds in northern Europe and North Asia. During winter, it migrates to southern Europe, Africa, North America and South Asia, including India. A flock of 40 such birds has arrived at the Okhla sanctuary.

Common pochard: This diving duck breeds in northern Europe and North Asia. It migrates to southern and western Europe and the north part of Southeast and East Asia and South Asia during winter.
