I think we should not consider killing wild birds, although many people would suggest this in the name of protecting human being. I think the problem is that these crane has been encourage to come to this place in large number in winter because people would feed them. In recent years, bird specialist has thought aboutb this problem, and have decided to reduce of the number crane in a single place. However the change in practice would need time for the crane to be adapted to it.
With the urgent outbreak this year, I think one should try to seperate the cranes into smaller group by more drastic actions. On the other hand, people living at the site should pay extra attention to personal hygiene so as to prevent infected by the virous. Panic action would not be helpful.
