I walked along the river as usual this morning. The sky was clear so it was very comfortable day. At that time, I heard the heron’s shriek. I sensed something with unusual voice. The marten just bit the heron on its body. I was terribly shocked with what had happened. I didn’t know what to do. I can’t help the bird. I felt really sad. My friends(photographer) ran to help. Mr W went to the river and he went to sandbank. And then he took the bird. “This bird is still alive but it will soon die, sorry.” I understood the food chain, but that bird was so poor!
