Many Little Terns have already migrated to Japan. Males were competing against other males for their partners. The technique of hunting is the best way to appeal them. The females watch them and decide which male is fit for. The drama could be observed in the Tama estuary in Japan. I do not use TRIPOD at all. I will trust my two arms from now on. Their movement is so incredible. Wildlife are the real genius living creatures. They teach us many things. Of course, if you watch them carefully.
