As a first-of-its-kind exercise in the state, the forest department is expected to soon give its go ahead to the study of migration system of lesser flamingos, the smallest species of the bird, and a regular visitor to mudflats in Sewri-Mahul areas and Thane creek.

Where do you fly to? The study will involve capturing birds and attaching to their bodies a transmitter, which will provide information on their migration patterns. PIC/THINKSTOCK
