Many herons

 When it comes mid-September, as has been done in the past,

the drainage channel rubber weir for agriculture makes it goes down after the rice harvest. This September also was so.

Then, many herons that couldn't find this sight came to this drainage channel to take small fish for food.

However, as the water in the channel is so turbidity, the herons can not see any fish.

As a result, they were in leaving.

The targets I have been focused on are hunting Goshawk that aim at herons.
