Question

Ringing has proved that birds cover large distances. There is some evidence to believe that the woodcock on its winter movements flies from the Himalayas to the Nilgiris without a pause, a distance of 2,400km. The wild duck comes to our lakes from CentralAsia and Siberia flying 3,200 to 4,800 km over the Himalayas. The rosy pastor comes from Eastern Europe or Central Asia. The wagtail, about the size of a sparrow, comes from the Himalayan regions and CentralAsia to the plains. Smallest of all, the willow warbler, half the size of a sparrow, covers as many as 3,200 km to reach us every winter!
